Got a 4l60e issue. Any help is appreciated. I won't be able to get someone to scan the truck until Friday. I've searched a number of forums and I can't find anything exactly like I'm experiencing. The trans has a fresh rebuild with a shift kit and corvette servo installed...not sure on the brands of those. The problem I'm having is when I shift from park or reverse to OD (my truck has P,R,N,OD,3,2,1) the truck will not move. I can get the rpm's up and it will kick in gear hard and move, but I'm not sure if it's in first or jumping on to second...I've only tried that once. If I manually shift it down to first or second and without moving the truck shift immediately back to OD it will go on into first an shift thru the gears normally. Any ideas?
Thanks,
Eric
