Audi TT won't shift into 1st or 2nd

It is most likely a Rivet that holds the shift fork on the gear shaft. It is not a hard fix as all that is needed is to remove the old rivet head and replace it with a bolt with a Nylock nut. but the tranny has to be taken out and broke in half to do it. the part will cost you 10 cents but lots of labor. Hopefully the fork didn't damage anything on its way to the bottom of the case.

It is hard to say, online, so to speak, what the exact cause is because there are so many variables. I would take your Audi to a respected transmission shop and have a good diagnostic Tech test drive your car and pinpoint what the exact problem really is. Good Luck!

Good Luck, I have an 2002 TT Roadster. My car did the samething 2 1/2 yrs ago. I took it to a transmission shop (I had called Audi and was told the cost would be around $8,000.00) The Transmission shop rebuilt the transmission and re did the clutch ( since they had to pull the motor to get to the transmission) 6 weeks and $3800.00 later i got my car back. (also, the Transmission shop did not know how to put the TT back together-If it is done incorrectly it drives like crap) they finally had to send it to an audi dealer. Anyway, the clutch stopped working 3 times in the next year. The transmission shop repaired it 2 times and on the 3rd time claimed it was out of warranty and refused to work on it. I took it back to the regular Audi dealer i deal with and had them fix the clutch. They kept it a week and cost me another $4,000.00. The clutch went out a few weeks after it was repaired from Audi. And they repaired it free of charge. I have now gone 4 months and have not had any problems with the clutch... My advice "Make sure that the transmission shop knows how to work on Audi's they are very sensitive. Also, make sure that only Audi parts are used."
