CAUTION!
• Keep component parts in group for each
subassembly and avoid mixing them up.
• Clean all parts with cleaning solvent
thoroughly and air dry them.
• Use kerosene or automatic transaxle fluid
as cleaning solvent.
• Do not use wiping cloths or rags to clean
or dry parts.
• All oil passages should be blown out and
checked to make sure that they are not
obstructed.
• Keep face and eyes away from solvent
spray while air blowing parts.
• Check mating surface for irregularities and
remove them, if any, and clean it again.
• Soak new clutch discs and brake discs in
transaxle fluid for at least 2 hours before
assembly.
• Replace all gaskets and O-ring with new
ones.
• Apply automatic transaxle fluid to all O-
rings.
• When installing seal ring, be careful so that
it is not expanded excessively, extruded or
caught.
• Replace oil seals that are removed and
apply grease to their lips.
• Before installing, be sure to apply
automatic transaxle fluid to sliding, rolling
and thrusting surface of all component
part. Also after installation, make sure to
check each part for proper operation.
• Always use torque wrench when
tightening bolts.
• A new discs should be soaked in ATF at least 2 hours
before use.Part Inspection and Correction Table

General Description
A/T DescriptionS6RW0D5101001
This automatic transaxle is electronic control full automatic transaxle with forward 3-speed plus overdrive (O/D) and
reverse 1-speed.
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an automatically controlled lock-up
mechanism.
The gear change device consists of a ravigneau type planetary gear unit, 3 multiple disc type clutches, 3 multiple disc
type brakes and 2 one-way clutches.
The hydraulic pressure control device consists of a valve body assembly, pressure control solenoid valve (linear
solenoid), 2 shift solenoid valves, TCC solenoid valve (TCC pressure control solenoid valve) (linear solenoid) and a
timing solenoid valve. Optimum line pressure complying with engine torque is produced by the pressure control
solenoid valve in dependence upon control signal from transmission control module (TCM). This makes it possible to
control the line pressure with high accuracy in accordance with the engine power and running conditions to achieve
smooth shifting characteristics and high efficiency.
A clutch-to-clutch control system is provided for shifting between 3rd gear and 4th gear. This clutch-to-clutch control
system is made to function optimally, so that hydraulic pressure controls such as shown below are conducted.
• When upshifting from 3rd gear to 4th gear, to adjust the drain hydraulic pressure at releasing the forward clutch, a
timing solenoid valve is used to switch a hydraulic passage with an orifice to another during shifting.
• When downshifting from 4th gear to 3rd gear, to adjust the line pressure applied to the forward clutch at engaging
the forward clutch, a timing solenoid valve is used to switch a hydraulic passage with an orifice to another during
shifting.
• When upshifting from 3rd gear to 4th gear with engine throttle opened, to optimize the line pressure applied to the
forward clutch at releasing the forward clutch, the learning control is processed to compensate the switching timing
of the timing solenoid at every shifting.
• When downshifting from 4th gear to 3rd gear with engine throttle opened, to optimize the line pressure applied to
the forward clutch at engaging the forward clutch, the learning control is processed to compensate the line pressure
at every shifting.
Employing the ravigneau type planetary gear unit and this clutch-to-clutch control system greatly simplifies the
construction to make possible a lightweight and compact transaxle.
A line pressure learning control is conducted to provide optimum shifting time at every upshifting with engine throttle
opened. If long upshifting time is detected, the subsequent line pressure applied during upshifting is intensified. On the
contrary, if short upshifting time is detected, the subsequent line pressure applied during upshifting is weakened.
