Known Problems

Vehicles may develop a start and die out condition or a transmission that defaults to second gear. Our technicians tell us that the transmission control module (TCM) may be at fault and require replacement. Our technicians tell us that if the TCM is replaced the pinion factor should be reset and the quick learn procedure performed.

Incorrect, worn, or contaminated automatic transmission fluid can cause shifting issues, noted mostly at speeds over 40mph. Our technicians tell us that repairs to correct this condition include changing the fluid and filter, driving the vehicle for 10miles and changing the fluid a second time.

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

An engine misfire may be caused by corrosion at the ignition coil and/or spark plug terminals or from cracked or brittle insulation on the spark plug wires themselves. Our technicians recommend complete inspection of the spark plug wires and replacement as necessary when engine misfires occur. If corrosion is noted on the coil towers or spark plugs those affected parts should be replaced as well.

When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.

Various driveability issues may be the result of low fuel pressure due to a failed check valve inside the fuel pump. If this is found to be the case the fuel pump should be replaced.

The connector on the input and/or output speed sensors on the automatic transmission may become damaged causing intermittent loss of speed control. Our technicians tell us there are wiring repair kits available to repair this issue.

The anti-lock brake (ABS) warning light may illuminate. This condition may be caused by a faulty electrical connection at the ABS system and/or warning light relays. Our technicians tell us there is a revised wiring jumper harness available to correct this concern.

Automatic transmissions can exhibit a variety of shifting and noise concerns due to failure of internal components. Our technicians tell us that due to the fact numerous updated parts are available for this transmission a complete inspection of all internal parts should be performed if the transmission is disassembled for overhaul.

Instrument cluster gauges, panel lamps, and electric door locks may not operate, and the courtesy lamps may remain on. These faults are commonly caused by "logic lock-up" of the body control module (BCM). If this is the case the BCM should be replaced with a revised version.

The fuel gauge may read empty when the fuel tank is full. Our technicians tell us there is a revised fuel level unit available which should correct this concern.

A hard starting and/or misfire condition may be caused by fuel pressure bleeding down from the fuel rail. If this is the case the fuel rail may be at fault and require replacement.

Various transmission shudder type issues may be corrected by updating the software in the powertrain and transmission control modules.

A moan or howl may be noted from the rear when the brakes are applied. It is recommended to check an repair or replace all rear brake components as necessary. If the noise is still present after repairs are completed then our technicians tell us that revised rear disc brake adapters are available which may help eliminate the noise.
