Leakage Inspection

Leakage Inspection

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

Check the vehicle speed sensor cover at the transaxle. Install a new gasket if necessary.
Leakage at the transaxle pan-to-case gasket often can be stopped by tightening the attaching bolts to 14 Nm (10 ft. lbs.). If necessary, install a new pan case gasket.
Check the fluid filler tube connection at the transmission case. If leakage is found here, install a new grommet.
Check fluid lines and fittings between the transmission and the cooler in the radiator tank for wear or damage. If leakage cannot be stopped by tightening a fluid tube nut, install new parts. When fluid is found leaking between the case and the cooler line fitting, check for a missing or damaged O-ring, then tighten the fitting to maximum specification.
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 radiator cooler and the cooler line fittings.
Check the engine coolant in the radiator. If the 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 lines for 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 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 transaxle range selector lever, install a new seal.
If leakage is found at the transaxle internal harness connector, install a new O-ring.
If leakage is found at the output shaft speed (OSS) sensor, install a new O-ring.
If leakage is found at the turbine shaft speed (TSS) sensor, install a new O-ring.
