Close.
It won't work with tailshift 914 boxes or 915 boxes.

My Rennshift is a bit elevated on 2-3 stacked washers because the linkage part rubbed. I recall I was not the only one who did this on install, but it was not "supposed" to be needed. Anywho, for what it's worth, make the piece as shallow and narrow as possible. I still get a minuscule rub shifting to 1st with the Rennshift.

Keep up the great work!

That looks great, Chris! How much reduction will the short shift option give?

So this will also work with a Rennshifter?

Zach

Good question

That's the plan.
I'll probably install the second prototype in a Rennshift prepared car.

Good.

I haven't calculated it yet. I just made the 2nd holes half an inch higher.

So in a car with a Renshifter, your firewall aft kit and shift console kit, what will this get me?

Will it improve shifting if I already have the shifter adjusted?
Zach

While it may shift well, it may also still run like shit....just saying

This mechanism will help one find the best adjustment quickly and easily.
Slight adjustments can be tested without fear of losing the baseline position.
It will only improve your shifting if your current adjustment isn't as good as it can be.

I redesigned the worm support block after the testing the first prototype.
The first unit had a support pin in the center of the worm but it was only held from the bottom, which created too much backlash.
Now it rides in a 3/8" dia. pocket just large enough for the worm to turn without noticeable free play.

Here's a pic of the second prototype installed under a Rennshift.

Installation only takes a few minutes but does require the shifter to be removed from the tunnel.
Adjustment was very easy even though the Rennshift adjuster opening is rather small.
After getting the lever fore-aft position set by sliding the gear on the shaft, I put it into 3rd gear and pulled it back out partway (onto the synchro) so I had good access to both the clamping bolt and the adjuster.
Then I loosened the clamping bolt and rotated the gear until the lever was exactly midway in the center plane, and re-tightened the bolt.
All 6 gears go in smoothly with equal spacing between the three planes.
I'll drive it to check the alignment in operation, and if a slight re-adjustment is needed it'll take about one minute.

No readjustment needed. Perfect the first time.

I have two prototypes available for further customer evaluation.
Price is $149, delivered.

PATENT THIS IMMEDIATELY. YOU'RE FUTURE IS SECURE! Good Luck. This should be on all cars. My tranny is shifting like silk now but at the next clutch I'll order one.

Chris I would be up for the trail but I am leaving for Afghanistan next week and would not be able to try it out for a while. Somebody else will be the lucky one but put me down for one when I get back. I finally got around to sending your tubes back. Sorry it took so long.

if my car was running I would jump on this trial. Gotta get'er fixed then I"ll see where you are. This really looks like a GREAT PRODUCT.

If nobody else is jumping on this, then I will take one.

Me three.

I would love to get one of the trial ones however I really do not think anybody wants my input.

Cars gotta be running first....just saying

Will you be seeing Dr. Evil any time soon?

If you have time to install the assembly right away and post your thoughts here then your opinion is valuable too.

I generally try to stay away from Dr. Evil. When he was working at my office, he corrupted my office staff. I had nice Mennonite girls working and now they are cussing, swearing and watching TV.

Just kidding, I do have to get over and see him. I would be happy to install it and give it a try. Where do I send the money and how much?

I hear Mennonitis is contagious.

HA! Not sure if I told you, but the girls were trying to get me to buy them booze. I felt like a wolf in a hen house....in a muzzle Stop being a stranger, Steve.

Look what showed up on my doorstep today

Steve, I haven't had time to start writing directions but it's pretty straightforward.
The basics are covered in post #62 above.

The ring gear fits pretty tightly but it will slide on the spline shaft with a bit of effort.
That ensures that it works as a repeatable stop for the fore-aft adjustment.

i decided that tonight would be the night that I would install Chris' new product. Like many of you, I have fought with adjusting my shifter for many years. I love working on my car. I have rebuilt most of my car at least once and iadjusting the shifter is by far one of my least favorite things to do.

Here is a summary of my experience with Chris' new product.

I do not have a center console so removing the shifter was done in a minute or 2. After removing the old shifter, I grabbed the shift rod with vise grips and slipped the nylon gear over the rod (tight fit however that is the point). After installing the new shift fork on the shifter, I installed the whole unit back onto the shift rod. Bolt the shifter housing to the floor and I was ready to try it out.

The adjustments were very precise and extremely easy. My initial emotion was anger. I thought back to all those times I spent pulling out my hair trying to adjust my shifter- no more of that now. The most difficulty that I had was finding my Allen wrench set. It's snowing here so I wasn't able to drive the car.

Total time spent installing- 12 minutes!!!

This thing is awesome. I am absolutely amazed. I see no problems whatsoever with this new shift fork. Everybody needs one of these!!!!!! The installation is extremely easy. I was able to adjust my shifter accurately in minutes.

I do not know Chris personally however I hope he makes a lot of money on this product. It is brilliant!!!!

Excellent, thanks for the review! I know what my next winter project is going to be....

Chris - any idea when these will be for sale?

Sounds like I may need to try one of these. The concept was sound, and now we have a trial

Too bad it snowed or I would have you bring it down or I would come up to try it

I'm working on custom tooling now so we can start cutting production parts in a couple of weeks.
I'll start taking orders once we have everything in place, and may be ready to begin shipping before Christmas.

Just sent in an order. Any new "tips" on doing the install ?
