I have a 2004 Z71 Tahoe with a 5.3 and a 4L60E. My wife took it to the store and when she went to leave, it wouldn't shift out of first gear. There are no warning lights on, the fluid level is good and the speedo still works fine. There was no issues with this vehicle prior to this happening.
I have only had this problem once before but it was with a 4L80E and it was an easy fix by cleaning off the speed sensor located on the top side of the case.
Does this happen with the 4L60E's as well or what else could it be?
