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 MAIN CONTROL VALVE BODY .

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 .

CAUTION: Do not try to stop the fluid leak by increasing the torque beyond specification. This can cause damage to the case threads and/or case fittings.

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.
