The check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wiring may be of help it this case.
Lack of oil changes can cause the piston rings to become clogged with debris resulting in excess oil consumption. Severe engine damage may result if the oil level gets to low. Engine dis-assembly may be required to clean or replace the piston rings. Our technicians recommend proper maintenance to try and avoid this expensive repair.
A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.
Some engines may develop an oil leak at the front of the engine, the source is commonly the front crankshaft oil seal. Our technicians tell us a revised front oil seal retainer gasket is available to correct this concern.
A severe engine oil leak may be the result of one or more of the camshaft plugs falling out of the cylinder head. The is most likely to occur in cold climates and is caused by the expansion and contraction of the cylinder head. There is a cam plug retaining kit available to secure new cam plugs in place.
A rattling type noise may develop from the front of the engine. This is commonly caused by a faulty timing chain tensioner. Replacement of the failed tensioner should correct this concern.
The fuel level sensor may fail causing erratic operation of the fuel gauge. Our technicians tell us that replacement of the failed sensor is necessary to correct this concern.
The 4WD indicator may say on in 2WD mode due to a faulty vacuum solenoid or valve. All 4WD vacuum hoses, solenoids, and valves should be inspected and repaired or replaced as necessary to correct this concern.
The check transmission light may illuminate with a stored code 61, gear ratio fault. This commonly indicates an internal transmission failure. Our technicians recommend removing the adapter case pan for inspection. If metal is found in the pan the transmission will require overhaul or replacement.
