I’m getting an intermittent failure P0740. In Over Drive The transmission won’t start out in the lowest gear and it won’t shift to its highest gear when at higher speeds. Sometimes it works perfect, If I shut off the 97 Jimmy to run in a gas station, I come out and it doesn’t work properly again. This just started happening 2 days ago. I currently start out in 2nd and manually shift to drive. Shifting to over drive to Drive doesn’t do anything different from Drive or vise versa. Any Help ?
