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

Leaks at the transaxle main control cover-to-transaxle often can be stopped by tightening the attaching bolts to 12 Nm (106 lb-in). If necessary, remove the main control cover and inspect for damage. Refer to MAIN CONTROL COVER .

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

Check transmission fluid tubes and fittings between the transmission and the cooler in the radiator tank for wear or damage. When transmission fluid is found leaking between the case and the transmission fluid cooler tube fitting, check for a missing or damaged O-ring, then tighten the fitting to specification.

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 radiator cooler and the transmission fluid cooler tube fittings. Refer to TRANSAXLE/TRANSMISSION COOLING - AISIN AW21/6F35 .

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 transmission fluid cooler tubes from the cooler fittings and applying no more than 345 kPa (50 psi) air pressure to the fittings. Remove the coolant recovery cap to relieve the pressure at the exterior of the transmission fluid cooler tank. If the cooler is leaking and/or will not hold pressure, install a new cooler.

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

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