Transaxle Oil Pump - (produces hydraulic pressure to operate, lubricate, and cool the automatic transaxle; its pressure activates the pistons and servos).
Transaxle Valve Body - (controls the flow of the fluid to the pistons and servos in the transaxle; it contains hydraulic valves operated by the operators shift linkage and by engine speed and load-sensing components).
Transaxle Pistons and Servos - (operates the clutches and bands when activated by fluid pressure from the valve body).
Transaxle Clutches and Bands - (applies planetary gears in the transaxle; different bands and clutches are activated to operate different units in the gear-sets).
Transaxle Planetary Gearsets - (provides different gear ratios and reverse in the automatic transaxle).
Transaxle Differential - (transfers powers from the transmission components to the axle shafts).
Many of the components used in the automatic transaxle are also found in the automatic transmission. Operating principles of these components are the same as the automatic transmission. The differential of the automatic transaxle is similar to that used on the manual transaxle.
Q1. What is the purpose of the output shaft of a manual transaxle?
Q2. In an automatic transaxle, what component(s) operate(s) the clutches and bands?Continue Reading
