MATERIAL SPECIFICATION
| CAUTION | Do not try to stop the fluid leak by increasing the torque beyond specifications. This may cause damage to the case threads. |
Leakage at the transaxle pan-to-case gasket often can be stopped by tightening the attaching bolts to 11 Nm (8 lb-ft). If necessary, install a new pan case gasket.
Check the fluid tubes and fittings between the transaxle and the auxiliary cooler. If leakage cannot be stopped by tightening the clamps or the cooler tube retainer, install new parts. When fluid is found leaking between the transaxle case and the cooler tube fittings, check for a missing or damaged O-ring seal, then tighten the fitting to maximum specification.
If the leak continues, install new fluid cooler tubes.
If leakage is found at the manual control lever, install a new seal.
If leakage is found at the transaxle internal harness connector, install a new O-rings.

MATERIAL SPECIFICATION
| CAUTION | MERCON®, MERCON®V, MERCON®SP, Motorcraft Premium Automatic Transmission Fluid and Motorcraft Continuously Variable Chain Type Transmission Fluid are not interchangeable transmission fluids. The use of any fluid other than what is recommended for this transmission will cause transmission damage. |
| CAUTION | The transmission fluid used for the continuously variable transaxle (CVT) is unique. When using any type of flushing equipment to flush the fluid cooler tubes on this transaxle, the machine must be fully cleaned of any solvent or residual transmission fluid not matching the type used on this transaxle. The smallest amount of the wrong transmission fluid or solvents will contaminate and damage this transaxle. |
| CAUTION | The transmission fluid used for the CVT transaxle is unique. Do not use water-based cleaners to clean or flush the cooler tubes or transmission damage will occur. Mineral spirits can be used to clean the cooler tubes, providing the cooler tubes are blown dry with shop air and flushed with clean CVT automatic transmission fluid. Use only clean CVT automatic transmission fluid designed for the transmission. |
| CAUTION | Do not attempt to clean or flush the oil-to-air (OTA) transmission fluid cooler. Contamination may remain in the cooler and eventually be returned to the transaxle causing internal transaxle damage. If the transaxle is to be overhauled or if installing a new transaxle, install a new OTA transmission fluid cooler. For additional information, refer to TRANSAXLE/TRANSMISSION COOLING . |
When internal wear or damage has occurred in the transaxle, metal particles or clutch plate material may have been carried into the torque converter and transaxle fluid cooler. These contaminants are a major cause of recurring transaxle troubles and must be removed from the system before the transaxle is put back into use.
Because this transaxle has a thermal bypass valve in it, the only way to carry out the backflushing and cleaning is to disconnect the cooler tubes from the transaxle and the fluid cooler, and flush the cooler tubes only.
If new fluid cooler tubes need to be installed due to being damaged or are plugged, refer to TRANSAXLE/TRANSMISSION COOLING .
If the transaxle is to be overhauled or if installing a new transaxle, install a new oil-to-air (OTA) transmission fluid cooler. Refer to TRANSAXLE/TRANSMISSION COOLING .
