The transmission extension housing seal may leak fluid, replacing the worn seal will commonly correct this concern.

An internal distributor fault could cause the Check Engine Light to illuminate, an engine misfire, or a stalling condition. Replacement of the distributor is commonly recommend to correct this concern.

Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.

The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

The idler arm or pitman arm may wear causing looseness in the steering. When this occurs the front suspension will not be able to be aligned correctly.
