How many miles? Sounds like mine. I let the dealership do the repair as at harvest I didn’t have time. Torque converter clutch was slipping. Put a reman trans in since the rest of the pickup appeared to have plenty of life left. 200k miles. Buddy with the same drivetrain had to do a trans at 200k too.
