What years does 4L60E transmission fit?
yes,,this could be an intermediate problem,,perhaps a bad connection of the wire harness at the transmission,,or,,maybe a sticking shift solenoid,,,but,,the transmission will work in this truck,,there shouldn’t be anything to do with the trucks computer not being compatible….
Re: what are the max miles on 4l60e transmission before fail Reverse kinda was finicky, every now and than it would slip but had a good life. I honestly think around 250-300k it should be rebuilt if its original.
None of the ’93 -’97 4L60E’s are directly interchangeable, except ’93 and ’94 and ’96 and ’97!!! Here’s a list of yearly differences that will show you why. Yes, some years will fit in others and may not even throw a code, but there will be an issue in the long run.
The 99 will fit and work, and so will the 93, but there may be a difference in the 4 wheel drive trans, because of the transfer case and the way it bolts up.
Will a 99 4L60E fit a 97?
It depends on what parts you are looking for. The bodies pretty much stayed the same from 1988 to 1999 with a few minor changes like headlights and grills, but you can still get a 99 grill to bolt on to your 89 truck. The fenders, doors, hood, bed, bumpers, etc all stayed the same.
