Transmission out, looks like an Audi trans, what should I look for?

[Erik Johnson]

I had no idea that the Audi A4 gearboxes were so cost effective these days.

Your clutch and flywheel look fine.

You could always have your gearbox rebuilt, but I suspect that this would cost you quite a bit more than simply grabbing a good used box at this point.

Good luck with your project, let me know if I can be of help.

So I took the transmission apart and found what I believe to be the issue. I don't know all the terminology so I'm sure I'll get it wrong but I'm sure you'll figure it out.

One of what I believe is a selector shaft has two aluminum pins that hold it in place and one of them had snapped. This allowed what I believe to be some sort of reverse detent or gateway part to pop out and it was in the bottom of the transmission. All the gears look fine and the fluid had nothing unusual in it. I plan to just buy the pins (if I can), replace them, put the reverse parts back in place, new fluid and bolt it all back together.

Top photo is the broken pin and the other pin which has bad wear from doing all the work (poorly) of two pins. The second photo is of where each pin would go and the shaft they should be supporting. The last photo shows what I believe to be some sort of reverse gate mechanism. The brown inner plastic piece had popped out somehow. The notch fits in the selector shaft. It was removed when the second photo was taken.

Going to hunt down parts now.

Thanks for the offer Eric. Confirming my belief about the friction disc was helpful. Crossing my digits that the pins I need are inexpensive.

Finding a broken selector shaft is actually great. No guessing as to what was wrong when you find an obviously broken part. Hope parts are cheap and you can get back on the road quickly.
As for the clutch, i'm with you on this one, don't fix what ain't broken as going back in is so easy. Years ago I had a GSXR1000 motorcycle and the clutch was a little weak and would slip at times. I took out the clutch discs (11 of them if I remember correctly) and the ones closest to the flywheel showed the most wear so I swapped positions and put the better looking ones near the flywheel and put it back together. Rode it like that for 2 more years with no slip and sold the bike. It was just too easy because if you had a 2x4 under the kick stand the bike didn't even lose a drop of oil while changing it out so no loss but a half hour of my time if it didn't work.
