I got this unit to solve the gear hunt/shutter shift (2,3,2). I got it installed today and it seems to have cured the issue.
arty018: It was really simple to install and I waited until a scheduled fluid change to do it. I hope the gear hunt is gone for good. I'll give it a week and post the results. Keeping my fingers crossed.
Dodge "RE" Governor Solenoid to GM
