Whats going on my fellow chevy lovers. I have a 2001 chevrolet tahoe 2WD. She shifts from 1st to 2nd just fine, but it seems to be a issue shifting from 2nd to 3rd. I changed out 3 transmission solenoids (1-2, 2-3, 3-2) and I still have the same issue. Does anybody know whats going on with my baby!? Advice would be much appreciated.
