Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Automatic transmission:
TH-125 automatic transmissions may shift late or not upshift at all. The problem is a stuck throttle valve inside the transmission. (1990-94)
Transaxle leak:
The right front-axle seal at the automatic transaxle is prone to leak and GM issued a revised seal to correct the problem. (1992-94)
