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 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

Q2. In an automatic transaxle, what component(s)
operate(s) the clutches and bands?
