02 silverado 4wd 4l60e shift problem
Checked fluid, RED, and smells "used" maybe slightly burnt
Doesnt matter throttle position, low throttle or WOT (changed TPS)
Put on a Tech 2 (no codes)
Checked solenoid and servo function( seem normal )
Fluid was changed by a dealer before i bought it 1 yr ago (7k miles ago)
