My 4 speed manual does not shift into 3rd gear, so around Thanksgiving I will park it for the winter and put it on jack stands. I want to remove the transmission and rebuild it during the winter. What is required to remove the transmission? Adams' Apple2009-11-29 21:53:48

 not too hard to remove, general hand tools , a transmission jack or a good roller jack, if you are gonna replace the clutch assembly you will need a clutch alignment tool.You will need an extra set of hands and about a case of budlite,,make sure you take note of how it comes apart, and the set up of your shifter linkage, the members here will walk you thru it,, good luck rd

basically as rick said... its not tooo overly complicated, basically you'll have to remove the driveshaft(trust me on that, tried leavinig the differential end attached, not enough room to manuever the tranny out with it in, UNLESS you have a bolt in transmission crossmember, then its a breeze), the shifter(after taking the tranny mount you can drop the tranny down a little to get to the side of the shifter to take it off, then take the linkages off), the tranny mount, and it would be eaiser to to take the 4 bolts holding the transmission to the bell housing then slide out the tranny to the rear then nose dive out the front. Bellhousing is pretty straightforward at this point. As Rick said, do take note(or even pictures with a digi cam) for the shifter linkage mainly.  good luck, and when time comes we can walk you through it.

And, as has been repeated many times on this forum, the AIM has great diagrams.

Transmission is removed, thanks for the tips. The rebuild kit is in and now waiting for warmer weather to put it back. First have to get new tunnel insulation in place. Also have to rivet in new clips as they are all gone.

Ok , I rebuilt the transmission over the winter, new bearings and syncros and sliders. Transmission is back in and the good news is that  I now have 3rd gear back. In the past I could never shift into 3rd gear.  I have a temporary eBay CPlus shifter in as the original went to Hurst for rebuild, but that takes 8 weeks.
The issue is that there is some kind of ticking noise near the bell housing. I drove the car around the block and all gears work OK, but there is a ticking noise. The noise is also there when the car is stopped and running in neutral and also with the clutch in.
The car is back on stands as now I need to find out where the ticking comes from.
Anyone have any ideas?

Hopefully you replaced the clutch, pressure plate, release bearing, pilot bearing/bushing and resurfaced the flywheel.  If you did jot do all suggested, the ticking is will be solved when you remove the transmission and accomplish all of the above.  Good luck. OH6A2009-07-25 18:18:43

I replaced the clutch, pressure plate, pilot bearing and resurfcd the flywheel.

 
The transmission did shift into 3rd for a wile and now does not. I am not sure if the alignment is OK or not. I also have a vibration at 2500-3550 and it;s likely clutch related. It's a real pain.
 
No time to work on it as I'm in China for 5 weeks now. Car is on jacks to get the brakes redone when I get home.
 
Always projects on these C3's; but that is part of the enjoyment.
 
Right now I'm happy having 3 of the 4 gears.

Don't take this the wrong way, but what kind of clutch is it and which way did you install it? From what you wrote in, it sounds like you covered everything else. Vibration? That's gotta be something not balanced or misalligned. Could the end of the trans shaft be too long and pressing against the crank? When the flywheel was resurfaced, did they also check it for balance?
Good luck.

Finally solved the mystery of no 3rd gear. I adjusted the travel of the rod by two turns and now I have third gear.
