Mechanical Components And Functions: Lubrication: Notes
The transaxle fluid enters the lubrication circuits after flowing through the transaxle fluid cooler. The transaxle fluid filler is mounted at the front of the vehicle. When the transaxle fluid is not up to operating temperature, an internal thermal bypass valve allows the transaxle fluid to bypass the transaxle fluid cooler. When the transaxle fluid circulates through the transaxle fluid cooler, the transaxle fluid returns to the transaxle from the transaxle fluid cooler tubes through the back transaxle fluid cooler tube
The transaxle fluid enters main lubrication circuit through the transaxle case and flows through passages in the input shaft to lubricate the transaxle.
The transaxle fluid in the input shaft circuit flows from the back of the input shaft toward the front of the input shaft and passes through ports in the input shaft to lubricate the planetary gearset, clutches, final drive assembly and other components of the transaxle.
