Ram tranny problems

In reverse the front clutch pack and the rear band are applied.

He said the valve body needs replaced too? That's a rare thing to have to replace. The overdrive solenoids and a pressure switch are screwed to the valve body and as Mully said it is common to replace the electronic switches and torque converter as metal and friction material clogs them up. They aren't real expensive though. Probably less than $250 for the converter and electronic switches from one of the sources I referenced in the links above. Do you have another place to check with? I would after the incorrect information he told you about the rear strut falling out.
