I have been having issues with my tranny locking and unlocking the tc, im trying to locate electrical problems, have redone my grounds, ran a new ground from pcm to battery, and still nothing. This is on a rebuilt transmission and the problem sort of grew from when it was first installed. It was a bit soft on shifti g then, and now wants to kickdown, mainly in od but has occasionally happend from 2-3. Could this be a band issue? Need this truck ready to go by friday and am scrambling to finish. Thanks.

 

Did you change out the TC lock up solenoids?

 

All the solenoids and sensors have been replaced, the only things left could be any issue on the truck side or the vlave body.

Sorry about late response, just got the email from Db.
