I have been having a problem with my 2001 Jetta TDI (01M Transmission) going into reverse.
Symptoms: Would not shift into reverse unless you rev it up - then it would BANG into reverse and drive normally in reverse until you shifted out of reverse again. Also - I have noticed some torque converter clutch slippage. The car will not go into reverse anymore at all. All the forward gears shift fine, with the exception of some TCC slippage when putting my foot into it. There is a certain amount of silver material (no chunks) on the pan magnets.
I am comfortable turning wrenches, have a VW 01M overhaul manual and thought - what the heck - lets pull'er down. - I don't really want to overhaul the tranny per-se' I just want to fix the reverse problem - was hoping to see something obvious when I opened it up, but no luck! So, now I am hoping someone like CoolAirVW who is knowledgeable in these things can give me a hand! I will add pics, but pics were an afterthought, so the pictures are of the transmission out, and disassembled.
I did find one thing wrong, but doubt it is the reason that it will not shift into reverse. I found the dish washer with a broken finger, and another finger about ready to come off - broke off when I touched it. (last pic)
If the mechanics of the transmission for the most part look good - is it in the valve body? I hate to spend the money on a valve body just to "see."
Thanks for the help!
