I have ran a scan with the vagcom and got the po741 code for the first time on a 2000 a6 Transmission shifts well and have not had any problems with it except for the cel i just scanned. I am going to change the fluid and filter this weekend and change the tcc solenoid but i cant find any info on which solenoid is the tcc lockup. Thanks for any info on which solenoid to pull.

Evidently even the repetitive failures did not stop Audi to sell defect transmissions.

 

From i have determined there are several things that will cause this code, so i think i will change fluid and filter, inspect and clean The two solenoids resposible for the torque converter lock up.The mechanic has told me he has had some sucess with using redline fluid change and inspecting the wiring and solenoids. If this doesnt work the neigbors had better keep the kids inside for the next week or there liable to here some words they have never heard before.
