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 or 440-T4 automatic transmissions may shift late or not upshift at all. The problem is a stuck throttle valve inside the transmission. (1990-94)
Automatic transmission:
4T60E transmissions may drop out of drive while cruising; shift erratically; or have no second, third, or fourth gear because of a bad ground connection for the shift solenoids. (1991-94)
Engine noise:
A tick or rattle when the engine is started cold may be due to too much wrist-pin-to-piston clearance. (1994-95)
Engine noise:
A rattling noise from the engine when the car is started after sitting is often caused by automatic-transmission pump starvation or a sticking pressure-regulator valve. (1991-95)
Steering noise:
The upper bearing mount in the steering column can get loose and cause a clicking, requiring a new bearing spring and turn-signal cancel cam. (1994-96)
Transaxle leak:
The right front-axle seal at the automatic transaxle is prone to leak. GM issued a revised seal to correct the problem. (1992-94)
Valve cover leaks:
The plastic valve covers on the 3.1-liter engine were prone to leaks and should be replaced with redesigned aluminum valve covers. (1994-95)
