Is your tranny feeling like this?
Send it to me and I will make it feel and perform like this!
If your tranny is feeling its age, grinding, and popping out of gear I have the solution for you! If you have checked the other, outside of the tranny causes for these symptoms and found them to be ok then your tranny may be in need of a rebuild.
Some outside of the tranny causes for some of your shifting woes:
-Shifter bushings along the shift rod
-Cone set screws
-Tranny cable adjustment, shifter adjustment
-Clutch, TO bearing, pressure plate
-Engine and tranny mounts
So, you have checked all of the above and it is still not working as it should. What do you do!?
Send it to me!
Repairs, modifications, conversions, you name it.
I am interested in getting your car shifting correctly and lasting a long time while providing you with the greatest value and service. If you have questions I would be happy to help you. If you want to take pics of your gear stack and get an opinion feel free to contact me. Do you want to bring it by and have me take it apart to diagnose it? I will gladly do this, and for free. I will diagnose any tranny for no charge.
I have a great stock of excellent used internal parts for much less than new with no loss in performance, as well as new, if you are interested. I have many different gear sets. I highly recommend all new main bearings; input shaft (x2), pinion shaft (x2) and differential (x2). I stock these bearing set at far less than retail.
For shipping instructions, PM me.
Any questions feel free to PM me

Here is also a link to an excellent thread by DNHunt on how to rebuild the tranny if you want a basic overview http://www.914world.com/bbs2/index.php?showtopic=40904&st=0
How to remove the stack from you tranny out of the car:
Step 1. Remove the shift console and the reverse switch with its pin
Step 2. Remove tail cone. Be ready for the reverse gear and its little bearings to fall out. You should now be looking at the business end of the tranny gear stack.
Step 3. Select 5th gear by taking a socket extension and pushing in the 4th/5th shift rod. Its ok to use a hammer, just dont beat the hell out of it
(4th and 5th Shift rod in neutral)
(5th gear selected)
You can now remove your gear stack by lifting at the intermediate plate.
***NOTE***
When you remove the intermediate plate you will have some gaskets between it and the case. These are of a particular thickness and need to be replaced with the same to keep the pinion shaft depth the same. Use a micrometer to measure the thickness of these (usually more than one) and keep that number handy. When you reinstall you need to measure the gaskets that come with the new kit and replace with ones that are of the same thickness.
Also, here is a link to Red-beards article on how to fix 1st with the tranny in the car. It can be used as a guide to how to remove the stack in the car.
http://home.san.rr.com/pb914/rebuild/
So, now you have recieved your rebuilt gear stack and you are very happy How do you reinstall it?
Like so:
Step 1. Select 5th gear on your gear stack.
Step 2. Place the correct thickness of gaskets on the tranny case rear.
Step 3. Place the case on blocks leaving extra room under the center for the drive shaft as it sticks out farther than the bell housing. Allign the stack, intermediate plate and drive shaft in the case and lower into position. Be careful of the output seal for the drive shaft. Make sure the drive shaft moves through it with out catching the lip and causing the spring inside it to come out.
Step 4. Once the stack is installed, reassemble the 1st/rev gear stuff (make sure the flat needle bearing is UNDER the gear on the intermediate plate side!). Now put the tail cone back on.
Step 5. It is now time to put the tranny back into the neutral. In the first pic you can see the shift rod notches are off center. Take a screwdriver and push the 5th/4th shift rod so it is centered. It should look like the second pic.
Step 6. Once in neutral, put the shift console back in. The shift console only gets the O-ring. The gasket that comes with the seal kit is for the plug of the tail shifter that goes there, not for the side shifter console so don't use it.
Step 7. Reinstall the reverse pin and switch.
Install the tranny and enjoy!
Next to come, how to allign your shifter.
that looks great...i just got my sideshift..now i gotta start saving again
do you have any need for used parts or a case or anything, i have a partially dissasembled tailshift...dunno if/what kind of used parts you might use
You may be able to use some of the parts for your own tranny. We shall see.
Mine might need a rebuild,
I also have a 901 that I got with a parts car,
Can you do anything with that?
Witch tranny is better?
Thanks John
rock on mike!
John, just PM me and we can talk about what you need.
I know what I want for Christmas! Of course the gear stack may not make it too you until February...
how much for a rebuild of a stock tranny and also install limited slip or Quaff? Have several Trans but not limited slip. Live near Cumberland, MD
Bill
Hey Bill,
PM me with exactly what you are lookng to do and I will see if I can get a time set aside for ya.
Thanks,
Mike
whats the best shipping from mid oklahoma for a full transmission?
i dunno whats wrong exactly, but cars not drivable.
driving it kind of hard (after a clutch disc pressureplate and thowout replacement) and i get this loud CRACK and now the car rumbles when in gear and has no power to the wheels.
Hey man, let me try to save you some money. If you have a "CRACK" and now nothing goes then your box may be done for as you may have just put a bunch of metal pieces through your diff. It may be in you rbest interest both money and shipping wise to pull the stack out as per my instrucitons and look at the teeth on your pinion and your differential. If they are gauled you would do better to have me get you a core tranny down here and rebuild it. A core would only run you about $75 over what shipping yours to me would cost. I have shipping instructions in teh first post. Coast to coast on GreyHound is about $70 so you should be a littl eless since you are closer. If you want to talk in more detail about this, feel free to PM or email me.
Dear Dr. evil,
I have a '74 914. It has a 2.0L motor and the trans keeps popping out of 2nd gear. I followed all your previous advice of things to try before calling you. I am desperate in need if a gear fix. Can you help me? I'm located in the panhandle of WV and can deliver the unit personally.
Steve
(304) 298-4216
Steve,
Yup, I can help you. The only thing is that I am booked until the end of the month. If you want to schedule a time in Sept to get this done then there will be no problem and a quick turn around.
Thanks for reading the whole post above and trying all the things I listed. I constantly have to refer people back to it and it takes time to do such. Youare already a step ahead
Dear Doctor,
I have a souped-up 3.0 SC engine mated to a side-shifter 901 with a ZF LSD. Now for the bad news:
- 2nd and 3rd grind if shifting occurs anywhere near top RPM's; oh, if I wait > 2 seconds they don't, but by then I'm doing 3 Mph
- 1st and reverse grind when engaging from idle after holding the clutch down for < 3 seconds; this one I can live with, and provide FYI
I'm a complete mechanical ignoramus, with no hope for reformation any time soon. Can you help me? What happens if surgery reveals terminal condition in there? Can you source parts, etc.? $500 all going well, really?
Cheers,
J.
J,
PM coming.
Doe Dr Evil do 915s?
T.C.
Yup, I do.
Hi,
If you do 915's...you must do the 930 as well...correct? I have a pretty fresh 930 box with less than 5000 miles. While setting up the cable shifter and clutch, I managed to burn the 3rd gear synchro a bit. It isn't terrible...but it is annoying when it grinds going into third. If all you do is replace the 3rd gear synchro...how much should that cost (assuming everything else is unmolested)?
Thanks,
Bill
I can do the 930, yes. The amount of work it takes to extract 3rd and change the teeth only is less than a full rebuild so I can charge less. I'll PM you and we can discuss it.
I have a transmission in a garage in Indianapolis, but I'm in Texas. How much would it cost for you to go to my house in Indianapolis, look at the two transmissions that are there, then pick the best one, take it home with you and then rebuild it, clean it, and make it work in my 3.2 project?
Well, I am almost a doctor so you would be paying 3/4 of the doctors fees + specialist fees + mileage + time + food and lodging + hookers + clean up....etc.
I figure $1,000,000 ought to cover it
sweet! count me in...I'll have my sister leave a check for you on the front porch. Just look under the mat!
Seriously, I'll be home for a few days in Sept. I'd love to send you a tranny to get super-sussed. I've got the original tail shifter from my 72 and an unknown side shifter that I got from Craig when I bought the car.
Sure man, let me know when
Dear Mr. Evil,
i have a 915 with flipped ring & pinon that needs to be checked out and i'd like to have a limited slip and the WEVO sideshift cover/conversion added ...
is this something your Evilness would be interested in?
Andy
Yes, I can do that, BUT, how fast do you want it?
Right on, send it to me when ever you are ready. If it weighs more than 100#, Greyhound may not take it, though Just strip all of the unnecessary parts off of it like the pully housing, throw out bearing, etc. This usually gets it to about 99#
I had a '75 914 2.0 when I was in college in the 80's. I loved it and periodically I think about getting another POS 914, I mean Porsche 914, again. It really was love-hate, with all it's maintenance. Anyway, I found you through Camp 914. My problem is not with a 914 but a BMW. I have a manual '98 528. The tranny is bad, but driveable. Do you, or do you know someone like yourself of good repute that can rebuild one of these? I'm looking at $2,500 for a BMW factory rebuilt, which is actually a very good price. Dealers are desparate and are discounting factory parts greater than before. But you rebuild a 914 tranny for $500 and you have a loyal following. So I thought I'd ask of whom I might inquire.
I wish I knew someone, but I am pretty specific to Porsche gear boxes. There is a possibility I could do it for you, but it would not be a quick job as I would need to do some research first to see how exotic the box is. If it is not very unique, and I can find internal parts for ya, it would not take too long. PM me if ya wanna talk about that option
Dr. Do you have a bell-crank rod (just the rod) that threads into my 914-6 intermediate plate?
T.C.
I'll see if I have one. You didnt have one with your box, did you? I would have removed it and taped it to the box if you had one.
I don't remember if it had one back then, it doesn't now. Thanks for checking for me.
T.C.
Nope, none here. I dont remember it having one, and if it did it would be in my spare parts bin as I dont use/need them. Sorry man.
Got any sources for them? Are they available at a Porsche Dealer or should I put a WTB ad on Pelican (I'm assuming the the rod is the same from a 911 to 914-6)
T.C.
They are not hard to get last I checked, but I made one when I needed one for my car. Long bolt, cut off the head and drilled a hole for a cotter pin
Hi Mike,
I just drove my newly minted 1974 914-6 (3.2) for the first time yesterday, and now I have to get the interior installed. I'd like to budget for a rebuild of my '74 901 side shifter. My question is can you change the gearing so that I can continue to use it as a 5 speed rather than as a 4 speed starting in 2nd gear? I am a parts collector, and recently bought a 914-6 5th gear that Captain Crusty had for sale, so if that was a good purchase I've got that on hand already.
BTW, the CV Joint bolt sets I bought from you sometime back were an easy install and look good.
Mike Knox
Hey Mike,
The 5th for the stock /6 is actually a smaller gear than the ZD in the /4 901 so you would be experiencing higher fwy RPM. The reason for the higher RPM is that the /6 needs more cooling. As for making your box a 5spd that has a taller 1st and changed 2nd, bring lots o money! You will need, at the minimum, a 904 shaft ($1800 or more) so I can install a different 2nd on it ($$). Very tall 1st gears dont really exist, but I can put the tallest one on and that would be $$$ for the parts. The most cost effective way to make a taller box for your car would be to use stock 2nd-4th (can mess with them a little if you really want) and put a flipped H gear in 5th (about $500 for the gears). I'll look over the gear chart and see what I can come up with.
Thanks I appreciate it. I know already it's going to be fun having that engine push me around , but I love the idea of having all 5 gears available. Having said that I don't know if a 904 shaft is in the realm of near-term possibility in this economy. Like I said I have that 5th gear set from John on hand, and you described the exact reason I bought it. So incorporating it into the rebuild is a must. Tell me what you think the most intelligent way to go is.
Thanks again!!
Mike
Dr.Evil,
What do you charge in addition to the $500 rebuild to install a LSD?
Thanks
Van
I'll send you a PM, Van
Mike, I still need to look at the gear chart. I was, er, busy last night and am recovering.
Hey Doc,
I wanted to see how busy you are as far as 901 rebuilds.
I am putting a subie 2.5Liter engine and wanted a transaxle that would shift great and stand up to 180hp and 180ft lbs torque.
I wanted to discuss changing gears first(not so low) maybe second? to take better advantage of the motor or maybe use a higher 5th gear?
Your the Doc. let me know what can be done.
I hear there is an inexpensive way to go for a limited slip diff??
Thanks
Gary
Hi Gary,
For the 180/180 set up you are shooting for a stock tranny should suit you fine. Have you driven a stock 914 for comparison? If not I would recommend it so you know where to start from as far as gear changing. For a water cooled engine the high RPM of 5th is a bit of a waste in power and gas so you may benefit from a higher 5th gear such as a flipped H gear or HB.
Now, if you are dead set on swapping gears around, which = $$$, then I need to know what the power band of your engine is going to be. The gears should be arranged in such a way as to utilize the power band the most. Unless you have $1800 or more, 2nd gear changing is not an option.
As for cheap LSDs, I would like to know where you heard this as I have no links to cheap LSDs. There are basically 2 options; the quaiffe which is a geared unit, and stock which uses clutch disks that need to be changed out when they wear. If you are not AXing, an LSD is pretty much overkill and not cheap at around $1800 last I recall.
I can build you up a respectable box that will shift perfectly and handle your engine as well as steer you away from spending needlessly on upgrades that you may not need
Hi DR.
I read all of your posts,
The last one in regards to installation of returned gearhead,
read;
installation alignment of shifter to come.
Did I miss it??
Gary
Hey Dan,
I need a pic to be able to tell you what is up. There are a few ways people can use zip ties to make do....all of them not a good idea.
This discussion would do better in the garage as it would get more hits
The most common parts that need replacing are 1st gear slider ($450), 3 synchro bands ($75 ea) and a seal kit ($40). If I have good used teeth and bands I can sell to you for less with no loss in performance. I may even have a good used 1st slider when you are ready, but those sell out fast and are 1st come 1st severed.
Hi DR.
I have a 215v8 engine in my 914, I am looking to get a trans rebuilt with a 5th gear change to a highest ratio for highway driving. I also would like to trade you some 901 transmissions to keep my cost down, if you are interested. I will be traveling down near Hersey, PA. In the next couple weeks. Please give me approximate cost, an address and a contact number. I am not in big hurry to get it back, in a month or two.
Take Care
Bill
Bill,
Unfortunately, I am getting out of the rebuild biz by June 2010 and as such I am trying to get rid of stock. I only need one core to satisfy orders I have so several cores will not be useful to me. However, I can give that info to my apprentice that will be taking over as he can use them. I can do your rebuild, though. I may even have an HB gear available for you to buy to make your 5th taller. I will be out of town starting Sept 11-21 as I will be teaching rebuild clinics in the PNW and SoCal areas.
Let me know how I can help you
Sorry to hear that Dr. Evil but it must be time; pass on all those secrets to your apprentice and we will put him to work. I (shortly) will be sending you mine with the bad fork problem. Perhaps you can massage an easy solution. Enjoy the post grad times : c ) I am premed and two decades as a Paramedic in the field, it is time to shift to the ER and teaching I think. I will be fast on your heels soon~ Good day- Jzn
Wow
I got to meet the Doc in person when I picked up my rebuilt Tranny.
Thanks Mike for all your hard work and very fair pricing. I appreciate the advice since I barely know which end of the car gets the rebuilt trans.
Again, it goes in horizontally, not vertically?
George O.
Wilmington,DEjava script:emoticon(':driving:',%20'smid_25')
Nice meeting you too, George. Keep us all posted on how your voltagewagen comes along.
Quick question regarding my 901 box. I sometimes get a grinding noise when shifting from 1st to 2nd. When I shift from 1st to 2nd, I usually pause briefly in neutral and then shift into 2nd to help eliminate this, but not completely. All the external checks you list have been done. Does this sound like it needs a rebuild? What does the full rebuild entail?
If I sent you the gear stack to have rebuilt per your 1st post, can it be put back in per your instructions, or is there an additional step of adjusting the shift forks?
Thanks.
With what you describe, I would bet the 2nd slider, teeth and band are poo. I can swap in good used and save you $$ without costing you miles. When you get the stack back, it will be ready to drop in per my instructions. All adjusted, inner bearings prelubed, etc. The good news is this, since you inquire about just a stack rebuild you will have to pull the stack anyway. At that point, we will know if it has crapped out parts as you can take pics and post them. Also, I can get a stack done faster than a whole box rebuild.
Here are pics of the 2nd gear dogteeth:
Here is the 2nd/3rd slider from the 3rd gear side:
Here is 1st gear:
I want to take the 4th/5th gear slider/syncros/dogteeth off one of my extra gear stacks. I'm not sure how to remove these two nuts.
Is this one just on real tight?
I'm not sure how you get a socket on this one. Does the speedo drive come off first? I don't want to break anything.
Here are a couple of shots of the 2nd gear side of the slider. The teeth look pretty sharp to my untrained eye.
Those look sharp. The only thing I can assume might be wrong besides adjustment would be internals of the synchro band. Send me the stack and I will inspect and adjust.
OK, I am back in the biz. I can not stay away, I like the work, the people, the income to finance my hobbies
What's the deal when the tranny sticks in gear? First time, it stuck in neutral. Then a friend took off the side cover and levered the selectors back in place. Gearbox shifted fine in place, but next time on the track, it stuck again, this time in gear. Did the same thing to unstick, but obviously something's wrong. Is this something simple like a bent shift fork or something, or does the trans need to be rebuilt? Best guess? Thanks.
Sticking in neutral (cant select ANY gears) and then in gear is a sign of external issues. Maybe a roll pin issue on the shift selector.
It is better to post questions like this in the garage so it doesnt take so long to get answered. There are many in the know there, many thanks to my clinics as well
Are you still building trannys mine does not like down shifting to 1st and 2nd is getting a little sloppy. Looking at a time frame of April or so after i return from my deployment. Wantig a stock rebuild nothing crazy.
I definitely do. One word of advise, you are NEVER supposed to down shift into 1st. They were not intended to have that done regularly and it is an unnecessary move that wears out the most expensive part in the box needlessly. Let me know when I can help with your transmission.
Semper Paratus
good to know about first gear, i only did it at a slow roll at traffic lights. But 2nd likes to zing a little going in gear.
Check the clutch cable adjust first. If it is good, then you sound like you need a rebuild.
Dr. Evil...)
1st Gear in the 914 has typically been a disaster.
I use the CA stop method. I slow down to check if the coast is clear then...
Depress the clutch & engage in 2nd.
Skipping 1st gear when-ever possible.
1) I am building a Big Bore 2.2 with all the goodies.
2) Can we make changes to the gear ratios..?
3) I would like gear ratios to match the new motor.
Let me know what is possible.
Call the office to discuss business & pricing.
Fed Ex shipping the whole thing over to you.

Never down shift into 1st to slow down. The boxes are not made for that. Gears can be changed, but for a 2.2 you do not need to if you plan to use it on the road.
What times are you available for calls? I am on the east coast and am pretty busy with my primary job so phone time is limited.
Hey Dr. Evil,
I sent you an email about a month ago. I guess you didn't receive it. I read that you were doing a tranny clinic up here in Canada, not far from Toronto. I have a 915 in need of having an internal WEVO gate shifter installed as well as the WEVO side shifter installed. Would you be able to include this as part of that clinic?
Also, I didn't see anything in the post on your clinic about pricing for participating in the clinic. Could you please let me know how much it would cost as well?
Thanks alot.
Best regards,
Dino
Toronto
Dino,
The 915 will not be covered at the clinic. If you have a 901 to build then I can help you out. If you want to bring you 915 to me, or ship it I can do the work for you.
My email is makemy914go at yahoo.
My transmission just landed at Dr. Evil's doorstep. Very excited to have yet another item on my car sorted out soon!
Dr. Evil, Do you have a schedule of when and where you will be doing rebuild clincs. Thanks.
I noticed the original post from 2006 shows shipping greyhound coast to coast for a complete trans was $50 So fast forwarding to 2014 and I'm wondering what your preferred carrier is nowadays? And any idea on the cost?
I ask because I'm 1,200 miles away from Virginia so I have a hunch it will be cheaper to ship you mine at a later date vs attend the Williamsburg Clinic for some hands-on action.
***EDIT***
So I got off my lazy and got a quote from greyhound. Coast-to-coastis now $112. FYI Website shows Max Weight is 100lbs (a trans doesn't way more than that does it?)
Thanks
Matt
Pull the gear stack and send that, not the whole trans. Saves a lot of weight. BTW, Doc is in Pa, my shop ( where the clinic is ) is in Va
i haxe 2 814's one is a v8 and dont think the gearing is right for it
? can you open it and ck it and recommend the right gear ratios for the v8? and change the gears? please message me back with the dost for this service. the tranny seems ti be working fine otherwise. you'll find out more when you open it up.
Frikkin love 914 WORLD!
Hi Dr. Evil. Hoping you are still helping out fellow 914ers trying to get their machines operating normally!
My teenager son and I are in the middle of a restoration of a 1971-4 that we purchased summer of last year. It was inoperable for the past 10 years sitting in a garage. We got the engine running, and of course the shifting was terrible. We rebuilt the pedal cluster, and replaced all of the shifting linkage bushings, balls. There were no bushings anywhere so I thought that would solve my problem.
We did the adjustments, and it shifted much better (actually got into 4th & 5th gears) but still some grinding from time to time on the downshift into 2nd and some trouble engaging 1st - possible we need to look at my clutch cable adjustment again, but we just dropped the engine to get to work on the gaskets/tin, etc.
We don't know the exact mileage so with engine and tranny out, plan to inspect the clutch, flywheel and thinking would be great to look at the gears. We have no experience with transmissions and thinking having an expert work the gears could save me both time and money.
If you are still working would love to connect with you. Please let me know.
Thanks. Steve (the dad)
Mike i believe i will be sending you my transmission, ring and pinion was beginning whine a bit, it also has LSD. i also have a 5,000 mile rebuilt transmission stack already pulled and ready to be used for parts i would probably be sending this along with the whole unit.
Dr. Mike
I have a Transmission for my 914 that no longer can get into 3rd gear.
1st and 5 th are fine.
It is a clutchless electric that you rebuilt while still a resident. I actually drove to you.
Bushing and stick adustment are optimum, can't even get it into 3 rd from under the car manually. All the other gears move fine.
Do I send the whole unit or remove the stack?
Please let me know about shipping since you are further away.
Many thanks
George Ozer, O.D. (thought it might jog your rmemory, however I have always been quite forgetable)
