Hey guys just pickup a 1997 540i, runs great, shifts great. However, i have to get the car inspected soon in my own state and i have a Code P0740 (TCC circuit open)? They will be plugging in an obd2 scanning device into the car i know that. I guess my Torque converter is not locking up? doesnt feel that way anyway. SO, has anyone succesfully gotten rid of this code by not having to change out the Torque converter? I was told by PO it may just need a fluid change and the code will go away. His mechanic told him this. My next question is: Has anyone been able to manually lock the torque converter using a jumper wire or an on/off switch like you can do to the GM cars? Please let me know.
