anyone good with a 4l60e?
heres what I got. 03 silvy 5.3 4l60e 4x4 etc etc. heres the story. trans went out about 20k ago. that was routine. slipping, burnt fluid smell, the works. well I put a rebuilt tranny in it and now to present times. the trans all of a sudden just quit getting 3rd gear. no slipping at all. It goes through first and second just fine then revs like its in neutral. The fluid still smells nice and clean which is what is leading me to believe its not clutch packs. Its not throwing any codes for the shift solenoids either which is why im confused. Ive read forums and check fuses etc etc till I was blue in face. If I gotta put another trans in it, then that's what I gotta do but I don't wanna replace a good trans if its another problem. Any one got any ideas to lead me in the right direction?
