Transmission codes nightmare p0770 etc
 

Tranny started slipping. Got Transmission rebuilt by my mechanic who I trust has done lots of work for me. Codes before trans rebuild were p0770 and p0773.

Ran great after rebuild for 1 week but CEL came on.

Sent it back to the shop. They re-replaced solenoids with factory Toyota solenoid at their cost - charged me nothing extra.


Got truck back runs great. CEL came back aftet a week.


Very frustrated as the truck seems to be shifting and running fine. The only thing I am noticing or maybe I'm just looking for is that I'm cruising 60mph @2k rpm. Not sure if that's normal. I feel like I should be cruising 60mph around 1500rpm

Im about to have the dealership take a look but I'm frustrated. I have read these codes can be hard to kill.

Edit: just had the code read and it's telling me it's a shift solenoid E

60mph @ 2k rpm sounds about right. Did they install a new torque converter or did they reuse the old one?
