5A-99 Automatic Transmission/Transaxle: 

Operation check
Check pressure control solenoid valves (Pressure 
control solenoid and TCC pressure control solenoid) (1) 
operation in either of the following methods.
[Using regulated DC power supply]

1) Connect pressure control solenoid valve (1) with 

regulated DC power supply (2) as shown in the 
figure.

2) Turn regulated DC power supply switch ON, 

increase voltage of power supply keeping current 
within 1.0 A.

3) Check that valve (3) moves gradually in arrow “A” 

direction as voltage increases.

4) Check that valve (3) moves in arrow “B” direction as 

voltage decreases.

5) Turn power supply switch OFF.

CAUTION

!

 

Do not feed current 1.0 A or more, or 
pressure control solenoid will be burned out.

 

[Not using regulated DC power supply]

1) Connect pressure control solenoid valve (1) to 

battery (4) setting 21 W bulb (2) in between as 
shown in the figure.

2) Check that valve (3) moves in arrow “A” direction.

3) Disconnect pressure control solenoid valve (1) from 

battery (4) and check that valve (3) moves in arrow 
“B” direction as shown in the figure.

CAUTION

!

 

Set 21 W bulb in between, or pressure control 
solenoid valve will be burned out.

Removal and Installation

S6JB0A5106023

Removal

1) Disconnect negative cable at battery.
2) Pull out fluid level gauge and lift up vehicle.
3) Remove drain plug and drain A/T fluid.
4) Install drain plug with new gasket.
5) Remove oil filler tube (2) and A/T oil pan (1).

6) Remove A/T oil strainer (1).

7) Disconnect shift solenoid–A connector (1), shift 

solenoid–B connector (2), TCC pressure control 
solenoid connector (4) and Pressure control solenoid 
connector (3).

8) Remove solenoid valves.

9) After removing bolt (1) pull out transmission wire 

connector (2) from transmission case.

CAUTION

!

 

When pulling transmission wire harness out 
of transmission case, take care not to 
damage connectors and transmission fluid 
temperature sensor at narrow exist of case. 
Careless sensor treatment might cause 
sensor malfunction.

 

Installation
Remove removal procedure to install transmission fluid 
temperature sensor, noting the following points.
• For details of solenoid valves and their connectors 

installation, refer to “Automatic Transmission Unit 
Assembly”. Use new O-ring.

• For details of A/T oil pan installation, refer to 

“Automatic Transmission Unit Assembly”.

• Fill A/T fluid and check fluid level according to 

procedure described in “A/T Fluid Change”.

• Check for fluid leakage after warming up A/T.
• Tighten transmission wire connector bolt to specified 

torque referring to “Automatic Transmission Unit 
Assembly”.

Transmission Fluid Temperature Sensor 
Inspection

S6JB0A5106024

Immerse transmission fluid temperature sensor (1) in 
water or oil. Check transmission fluid temperature 
sensor resistance between terminals of connector. Thus 
make sure its resistance decreases as temperature 
rises.
If sensor resistance is out of specification, replace 
solenoid wire harness (2).

Transmission fluid temperature sensor resistance

5A-101 Automatic Transmission/Transaxle: 

Transmission Control Module (TCM) Removal 
and Installation

S6JB0A5106025

CAUTION

!

 

TCM consists of highly precise parts, so 
when handling it, be careful not to expose it 
to excessive shock.

 

Removal

1) Disconnect negative cable at battery.
2) Disable air bag system.

Refer to “Disabling Air Bag System in Section 8B”.

3) Remove glove box.
4) Disconnect connectors from TCM (1).
5) Remove TCM with 4WD control module by removing 

its nuts, and then separate TCM and 4WD control 
module.

Installation
Reverse removal procedure noting the following points.
• Connect TCM connectors securely.
• Be sure to enable air bag system after TCM is back in 

place. Refer to “Enabling Air Bag System in Section 
8B”.

A/T Relay Inspection

S6JB0A5106026

1) Disconnect negative cable at battery.
2) Remove integration relay No.2 (1) from fuse box 

No.2 (2).

3) Check that there is no continuity between terminals 

“E41-1” and “E38-8”.
If there is continuity, replace relay.

4) Connect battery positive (+) terminal to terminal 

“E38-6” of relay. Connect battery negative (–) 
terminal to terminal “E38-7” of relay. Check for 
continuity between terminal “E41-1” and “E38-8”. If 
there is no continuity when relay is connected to the 
battery, replace integration relay No.2.
