1997 Tahoe 1st, 2nd reverse gear only
Took in shop to check a front end leak. Turned out to be radiator & water pump. Picked
up after replacement, got 2 miles from shop going up hill and no 3rd gear although it
was OK up to that point. Got home on 1st & 2nd. Mechanic came out, checked
transmission fluid put in 3 quarts. Road tested, no change. Took back to shop & left.
Mechanic said it would go into overdrive if really pushed at 2nd. Said fluid was burned,
trans will have to be pulled & repaired/rebuilt. Would lack of fluid have caused this to
happened? Vehicle has 170,000 miles.Thanks.
