Transmission failsafe + code P0377

[RRPhil]

You quote the DTC as P0377 in the title, P0733 in the post and then P0133 in your other (fluid change) post. I hope you don’t have a job where numerical accuracy is important . Anyway, I assume you mean P0733 - which indicates a problem with 3rd gear. If it drives fine in manual mode then this points towards a issue with the intermediate clutch sprag as this is bypassed by the overdrive clutch in manual mode (to provide engine braking).

Sounds like an expensive repair.

Thank-you for the correction, RRPhil: It is code P0733.

While I can drive in manual without triggering failsafe, it is still a bit slow on the 2nd-to-3rd shift transition.

Do you still think it is the intermediate clutch sprag?
