Need help with check engine p0740 code tcc circuit transmission????
I'm new to this site, I always used automotiveforums before. I have a 98 bmw 318i w/ 150k(auto). My check engine light came on, had the codes read and it is p0740 which is tcc(torque converter clutch) circuit malfunction. I got so many possibilities from people on what it could be like low fluid but that is not it because the level is fine, torque converter( I hope not b/c the gears seem to shift fine). Bad connectors or solenoid.
My question is that I want to know if anyone had this problem and what they did to fix it? Do u think I need a new solenoid and do u know if the whole tranny needs to be dropped to get to it or is it inside the pan which I can remove and replace the thing myself. Any help would be appreciated. I know it has to be electrical b/c I cleared the code and started the car without even putting it in drive and it came on. Somedays the light does not come on at all.
any help would be appreciated.
