CAUTION: Do not try to stop the fluid leak by increasing the torque beyond specifications. This may cause damage to the case threads.

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

Check fluid tubes and fittings between the transaxle and the cooler for looseness, wear or damage. If leakage cannot be stopped by tightening a fluid tube nut, install new parts.

If the leak continues, install a new cooler line fitting and tighten to specification. The same procedure should be followed for fluid leaks between the cooler and the cooler line fittings. Refer to TRANSAXLE/TRANSMISSION COOLING article.

The cooler can be further checked for leaks. Refer to TRANSAXLE/TRANSMISSION COOLING article.

If leakage is found at the transaxle range selector lever, install a new seal.

If leakage is found at the transaxle harness connector, install a new O-ring.

The transaxle has the following parts to prevent external fluid leakage:

Sealer
Lip-type seals
O-ring seals
Seal rings
Seal grommets
Thread sealant
Pan fluid
