Help from the tranny Pros
Our truck started bucking during low RPM cruise. I assume the torque converter unlocking and re-locking. Seams to hesitate unlocking at decel just before stoppind as well. CEL came on but not the OD "OFF" warning.
OBD codes P0743 Torque converter circuit electrical and P1754 Coast clutch solenoid circuit. Any advise would be so much appreciated. Truck has 191,000 and I've been looking forward to bragging about it's 200,00th without any real trouble.
97 w/ E4od / 5.4
Thank You

Well I had to resort to the telephone to contact the pros.
A guy at my local tranny shop told me to check and clean the electrical connector on the trans, so I did. There was quite a bit of fluid and grime around and in the connector. I cleaned with brake parts cleaner followed by electrical parts cleaner and blew it out with compressed air. Problem seems to be resolved. Drove it to work today 40 miles on the highway shifted great and cruised flawlessly.
200,000 here we come!
