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.

General Description
A/T DescriptionS7RS0B5101001
This automatic transaxle is electronic control full automatic transaxle with forward 4-speed 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 planet ary 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 va lves, TCC pressure control solenoid valve (lin ear 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 prov ided 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 s witch 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 forw ard 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 opti mum 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 subs equent line pressure applied during upshifting is weakened.
Slip controlled lock-up function
Even at a lower speed than when the TCC gets engaged completely, control over the TCC pressure control solenoid 
works to cause the TCC to slip (be engaged slightly), ther eby improving the transmission efficiency. While such slip 
control is being executed, the oil pressure applied to the  TCC is controlled by the TCC pressure control solenoid so 
that the difference between the engine speed and the  input shaft speed becomes close to the specified value.
Also, during deceleration, the TCC is made to slip (be enga ged slightly) to raise the engine speed and enlarge the fuel 
cut operation range so that better fuel consumption is achieved.
Due to this reason, it is absolutely necessary for the automati c transmission to use ATF suitable for slip control. Use of 
any fluid other than the specified ATF may cause j uddering or some other faulty condition to occur.

Scan Tool DataS7RS0B5104009
As the data values given in the following table are standard values estimated on the basis of values obtained from the 
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good 
condition, there may be cases where the checked value does not fall within each specified data range. Therefore, 
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by  the scan tool are those detected by TCM and output from 
TCM as commands and there may be cases where the auto matic transaxle or actuator is not operating (in the
