Cutlass Supreme FWD L4-138 2.3L DOHC QUAD 4 (1991)
See Figure 1. The side-cover to channel plate gasket may be split or torn due to a raised surface or ridge on the sealing side of the pan assembly. This
raised edge can apply additional pressure on the gasket and a tear may develop. Vehicle mileage and vibration are factors which can accelerate the
potential of the gasket to tear. The entire inner case side cover gasket is suspect and should be inspected carefully for this condition.
CORRECTION:
See Figures 1 and 2. Install a new case side-cover pan which does not have the stamping "DO NOT PRY IN THIS AREA." Removing this stamping has
improved flatness on the sealing surface of the side pan and has reduced (but not eliminated) the opportunity of side pan leaking. It should NOT be
assumed the removal of the "DO NOT PRY IN THIS AREA" is a 100 percent fix. Vehicles with side pan leaks, regardless of stamping, should be
considered suspect for this condition. If transaxle already has a new style pan and a leak occurs at the inner side pan gasket, a second side pan (again,
without the stamping) may need to be installed to correct the concern.
Note:
Even though the stamping "DO NOT PRY IN THIS AREA" has been removed, it is NOT acceptable practice to pry in the described area when
removing axle and/or seal.
