Leakage Inspection: Notes
The transmission has the following parts to prevent external fluid leakage:
- gaskets
- lip-type seals
- O-ring seals
- seal rings
- seal grommets
- thread sealant
- sealing washers
Leakage at the transmission pan-to-case gasket often can be stopped by tightening the retaining bolts to specification. Refer to TORQUE SPECIFICATIONS . If necessary, install a new pan-to-case gasket only if gasket is damaged.
If leakage is found by the solenoid body connector, refer to SOLENOID BODY ASSEMBLY .
When fluid is found to be leaking between the case and the cooler line fitting, tighten the fitting to maximum specification. Refer to TRANSAXLE/TRANSMISSION COOLING .
If the leak continues, install new cooler line fitting and tighten to specification. The same procedure should be followed for fluid leaks between the oil-to-air cooler transmission remote filter and the cooler line fittings.
If leakage is found at the manual control lever shaft, install a new seal.
Check for fluid leaking from the end of the extension housing. Leakage can result from a damaged seal, missing garter spring, worn extension bushing, damaged speed sensor plug, or the output shaft retainer (vehicles equipped with a fixed yoke). Install a new seal assembly, bushing, or both, as necessary.
Inspect the line pressure plug for leakage. Make sure it is tightened to specification. Refer to TORQUE SPECIFICATIONS . If tightening the plug does not stop the leak, the case threads and/or plug could be damaged. Remove the plug and inspect the plug and case thread for damage. Repair as necessary.
