NOTE:
The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage. Refer to the transmission fluid specification for the correct transmission fluid.
NOTE:
Do not use water-based cleaners, mineral spirits, brake cleaner or solvents that may contain acetone, xylene or heptane to clean and/or flush the transaxle assembly, transaxle components or the torque converter, transaxle damage will occur. Use only clean transmission fluid designated for this transaxle.
- Carry out backflushing with a suitable torque converter/fluid cooler cleaner. Test equipment to make sure that a vigorous fluid flow is present before proceeding. Install a new system filter if flow is weak or contaminated.
- To aid in attaching the cleaner to the transmission fluid cooler tube, connect 2 additional rubber hoses to the transaxle end of the transmission fluid cooler tube as follows:
- Connect the cleaner tank pressure tube to the transmission fluid cooler return tube.
- Connect a tank return hose to the transmission fluid cooler tube. Place the outlet end of this hose in the fluid tank reservoir.
- Turn on fluid pump and allow the fluid to circulate a minimum of 5 minutes (cycling switch on and off will help dislodge contaminants in cooler system).
- Switch off the fluid pump and disconnect the fluid pressure hose from the transmission fluid cooler return tube.
- Use compressed air to blow out the cooler and tubes (blow air into the transaxle cooler return tube) until all fluid is removed.
- Remove the rubber return hose from the remaining transmission fluid cooler tube.
