I have a 75 914 and the transmission won't stay in 1st gear and is sometimes hard to shift into 2nd. If i replace the tranny with another one, is there a certian year I should buy? Can you convert the earlier year 914 or a 911 901 trans to fit the later 914's?

Check your clutch adjustment, unless its grinding really bad going into 1st and second, I would check your clutch first. As for the transmission, you would be able to bolt any 73 up trans into the car with no modifications to anything.

You want what's called the side-shifter transmission. They're all the same. However, they're all old and unless you find one you know has been recently rebuilt, it's not likely to be any better than the one you took out.

Fix your own, otherwise you'll just be fixing someone else's problems. At least you know the history of your current tranny.

i speak from experience

I have a 75. She shifts into 1st while moving. You have to go realy slow through the gate when going down into 2nd. The 914 transmission is the 901. Side shifter is better then tail shifter. The 911 tranny is a 915 isnt it?

Early 911s (up to '72) used the 901, which is very similar to the 914 gearbox, except for the end of the case and the shifter mechanism. The 915 was used on '72-on 911s until well into the '80s.

All 914 transmissions are the same except for the 914/6 model....different gearing. Tail shifters can be converted to side shifters if you have the external parts to swap out from another side shifter........

Is it easy to rebuild the side shifter 901 trans? I have an extra that is torn apart they look like typical manual transmission, just all gears. Any tips on rebuilding them or getting one rebuilt would be gladly appreciated.

The 914 transmission is the 901.

nope. the 901 is actually a 911 transmission. all 914 transmissions start with a 914 part number.
however, they are very similar to the 911 901s, hence the common mistake to name our trannies 901 ....

in any case, you can modify your tailshifter to sideshifter. the internals are the same. if you have a donor sideshifter, you can swap the parts needed to convert.

i agree with the other guys here, unless you buy a known to be freshly rebuild sideshifter, you'll never know if what you're getting is any better than what you have.

have yours rebuild and be done with it!

Are there websites that sell the parts to convert from tail to side shift? How difficult is it to do?

Sweet. Thanks!

The side-shifter swap isn't that hard. I just finished with mine 24hrs ago. I did most of the disassembly and assembly. My friends Dad did the critical parts, namely the "shim", which goes between the "bell" and the intermediate plate. This stack of what looks like very thin gaskets is what sets the pinion in the differential. You have to be super careful with these as they are calibrated for that specific intermediate plate and case. Otherwise, just pay very close attention to detail (after reading redbeards article, and anything else you can find of course!). Not only do you have a lot of small parts to deal with, you have to remember the order they were installed in. Those suckers will fall out on you, and get all mixed up you if are not careful! Ask me how I know...
