Hi, i have an 01 sierra 4.8L 2 wheel drive with a 4l60e automatic trans. the transmission is having problems and i want to see if anyone has had the same problem or can confirm what i am thinking. In second gear it will hold up to 3,000 rpms, beyond that the rpms will sudenly redline if im still on the gas and the truck will not continue to excelerate unless i let off the gas and let it go into 3rd. it seems to me that it is slipping, like 2nd gear is bad (stripped or something). Im pretty sure it is 2nd gear thats bad but i wanted to see what others thought before i went ahead and bought a remanufactured transmission incase it is an easy fix.
Thank You.
Thank You.
