August 14, 2009I think I've seen this on this forum quite some time ago, but I can't find it now. In the glove box is a sticker listing "Service Parts Identification." From this list of numbers, I can find what transmission is in my truck. Does anyone have the ID #'s for transmissions, or can point me to where it's found?

August 16, 2009Just tell us what truck you have - year, model, engine, basic stuff. We can tell you what tranny you have. My bet is a 4L60E.
August 17, 2009Thanks..... Found the info I was looking for: M30 = 4L60E; M32 = 4L65E; M70 = 4L70E.
