Compatibility depends entirely on the gearbox model. Check the transmission nameplate before purchasing.
Replacing the housing requires a new paper or liquid gasket and an output shaft seal (simmering). You should also verify the condition of the output bearing and the 4WD solenoid.
Damage to the drive output housing can result in sudden oil leakage and transmission seizure. A crack near the shaft mount can also lead to drive shaft vibrations and axle damage.
This housing closes the front part of the gearbox (below the torque converter), providing bearing support for the front drive output shaft.
