transmission rebuild

[deerwd]

I got my workshop manuals a couple of days ago for my 81 911. You would have thought I was reading an epic novel with the amount of time I spent just thumbing through the manuals. Anyway, I was reading the sections on disassembling and reassembling the 915 transmission. It seemed somewhat straight forward. I was told I may need some synchronizing rings installed soon. Is the transmission that simple? From some of you that have done this, what are some of the real difficult procedures for the novice as it applies to disassembling and assembling the transmission?

This is something myself and a friend are giving thought to ourselves: Why not acquire a ragged out 915 and rebuild it? They show up on Ebay often enough. They're not terribly large or cumbersome. And it's not rocket science, although I think your idea of straightforward and simple might be a little different than mine is, just based on your level of familiarity and skill.

Hell, a year ago, I didn't know what a synchro was or did. Heh. And now I double-clutch my way down through the gears.

I thought seriously about rebuilding my own 915 and did not, instead handing it to John Walker for the rebuild.

Symptoms were grind in 1st gear unless dead stop, clutch in, flywheel slowed down. 2nd gear crunch unless JUST right into gear. 3rd and 4th fine. Decided to replace/rebuild all parts related to trans: coupler, shift bush, new clutch cable/horseshoe spring, rebuilt pedal 'rack, fresh Swepco. Helped, but did not solve, so resigned to saving up $$ and thought out the pros and cons of rebuilding myself.

In hindsight, would have loved to do this myself (I am good with a wrench), but John's short turnaround, the good price etc. turned my decision. Plus, I had bonus money in my pocket and John let me do a bunch of stuff on the car while it was on the lift.

I would recommend you try this yourself. If you do, do NOT short yourself on new parts. Further, don't drive the car a bunch more without getting this taken care of since you can really start to screw the trans up. Expect to put in fresh dogteeth/sliders/hubs (maybe; you can file the wear lips as well)/and other sundry pieces.

By the way, the car shifts magnificently. I can push that bad boy into first ANYTIME I want to.
