i have a 2000 gmc sonoma 4x4 zr2 everything works but all i have is reverse all of a suddon
Transmission has went out.
I would put the tranny out to pasture yet. The 4l60e is a piece but I have yet to hear of one loosing all forward gears suddenly. Reverse yah the sprag breaks but not forwards. I would be checking it out. Have you checked the shift linkage on the tranny?
