Leakage Inspection

Leakage at the main control cover gasket often can be stopped by tightening the main control cover bolts to 14 - 18 Nm (127 - 138 inch lbs.). If necessary, install a new main control cover gasket.

Check the fluid filler tube connection at the transaxle case. If leakage is found, install a new fluid filler tube grommet.

Check the cooler lines and fittings between the transaxle and the cooler in the radiator for looseness, wear, or damage. If leakage cannot be stopped by tightening a tube nut, install new parts. When fluid is found leaking between the case and the fluid tube connector, check for a missing or damaged O-ring then tighten the fitting to maximum specification. Do not try to stop the fluid leak by increasing the torque beyond specification. This may cause damage to the case threads. If the leak continues, install a new fluid tube connector and tighten to specification. The same procedure should be followed for fluid leaks between the radiator and the fluid tube connector.

Check the engine coolant in the radiator. If transmission fluid is present in the coolant, the cooler in the radiator is probably leaking.

The cooler can be further checked for leaks by disconnecting the fluid cooler tubes for the fluid tube connectors and applying no more than 3.45 bar (50 psi) air pressure to the fluid tube connectors. Remove the radiator cap to relieve the pressure buildup at the exterior of the fluid cooler tank. If the cooler is leaking or will not hold pressure, install a new cooler.

If leakage is found at the manual control lever, install a new manual control lever seal.

Check for fluid leaking from the differential seal. Leakage may result from a damaged seal, missing garter spring or worn front wheel driveshaft and joint. Install a new seal assembly or front wheel driveshaft and joint as necessary.

Check for fluid leaks in the pump to case interface. A leak may be due to a rolled pump lip seal or a damaged seal. Repair the pump assembly.
