1974 Chevrolet G30 Van 5.7L 3-2 Shift
Posted to GM Transmission on 5/2/2006 9 Replies

This motorhome runs great and drives very well, until you get it hot. When cruising down the highway in 3rd the trans will shift to second for apparently no reason. It's not an abrupt shift, but it slowly and smoothly shifts back to 2nd and won't go back to 3r...
