Audi Forum - Audi Forums for the A4, S4, TT, A3, A6 and more! - 2001 TT 6 speed swap INTO 2000 TT Quattro 5 speed

I have a good 2000 TT Quattro with a 5 speed that is going on me. It is the only stock and original part on the car left and has over 300,000 kms on it so I understand. I was talking with my mechanic about throwing a 6 speed transmission from a 2001 225hp TT and he believed I would need to swap everything that the 2001 drivetrain has to offer. I recently bought a 2001 225hp with a good 6 speed in it. I bought it so I could just throw everything from the 01 into the 00 and be done with it. I also plan on using the 225hp with the 5 speed once swapped for a winter car as the 2000 is not stock and a bitch to get started and get warm in this Canadian winter…

I am just confirming for the 6 speed to fit into the 2000, I would need to swap everything, i.e. the transmission, transfer case, the differentials, the drive axels, the axels themselves, clutch, etc.

So the big question is: Do I need to swap everything or just some things? If its just some things, I'm still okay with buying this complete 225hp since it'll be a good winter car.

Let me know, advice or opinion is welcomed
