4l60e tranny problems Im having problems outta my 4l60e in my 2000 gmc z71 its shifting fine until it warms up then it starts slipping. when i turn the truck off and start it again it shifts fine for a bit then starts slipping again. im unsure of what the problem is but i could use some info it has roughly 213,000 miles on the truck unsure of the trans.
Sounds more like an issue with the transmission going to a limp mode where the computer is putting the trans into a fail safe mode. The reason I say this is because of you cycling the key and it seems fine for a bit. I would start with having your vehicle checked for codes first. this might be a simple fix despite the mileage you have.
