I have a 1995 GMC K1500 (4x4) with a 5.7 v8. My transmission has gone out. It only has reverse so from what little I know and could find out, it seems to have broken the low planetary. I can find 4l60e transmissions all over the place, but I know there are many different versions. I need to know what year trucks will fit and work in mine and if the only difference in the tranny for the extended cab 2 door truck and a regular cab truck is the tail plate (which is what I have been told by the guy at the junk yard trying to sell me a tranny so I am hesitant to believe him). Errrr. Help? Anyone? Please....
