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

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

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

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

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

If leakage is found at the Transmission Range (TR) manual control 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
Transmission fluid pan
