Hello , I am Mike with a 97 G1500 Conversion Van that has trans problems.
It will not move in OD or D, I have to put it in 2 and shift it manually. Any suggestion will help

Going to need a bit more information. If you put it in drive will it move at all? Or does it start out on a high gear or a low gear and not shift? If you shift manually, does it go threw every gear?

Dan, If I put it in drive it will not move at all, once it starts moving in 2, i can shift it into drive and od and its fine. If I come to a light, or slow down, then I have to repeat the process.

Not sure what transmission you have, and I'm no expert in this area. But it sounds like your forward band may be OK, but your D-2 band may have a problem. SGP358 is the transmission guy here. Have you checked your fluid level and color?

Welcome to the forum dan it should be a 4l60-e or 4l80-e but prob a 4l60

welcome, hope you find what you need

Welcome. There are a few guys here that know their way around a transmission real well, so I think you'll get the help you need
