AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

TSB Revision

AUTOMATIC TRANSAXLE

23C-25

CAUTION

• The throttle should not be fully open for more 

than five seconds.

• If you repeat the stall test when the transmis-

sion fluid temperature is greater than 80

°C 

(176

°F), move the selector lever to the "N" 

position and let the engine run at approxi-
mately 1,000 r/min for at least one minute. 
Wait until the transmission fluid temperature 
returns to 80

°C (176°F) or less.

6. Move the selector lever to the "D" position. Fully 

depress the accelerator pedal and read the 
maximum engine speed.

Standard value: Stall speed: Approx. 2,300 

− 

2,800 r/min

HYDRAULIC PRESSURE TESTS

M1231205500114

WARNING

Do not let anyone stand in front of or behind the vehi-
cle while this test is performed.

CAUTION

The transmission fluid temperature should be between 70 
− 90°C (158 − 194°F) during the test.
1. Check the transmission fluid level and temperature. Check 

engine coolant temperature.

• Transmission fluid level: "H" mark on the dipstick

• Transmission fluid temperature: 70 − 90°C (158 − 194°F)

• Engine coolant temperature: 80 − 100°C (176 − 212°F)

2. Raise the vehicle so that the wheels are free to turn.
3. Connect the special tools (3.0 MPa (427 psi) oil pressure 

gauge [MD998330] and adapters [MB992127 ]) to each 
pressure discharge port.

4. Apply the parking brakes fully.
5. Restart the engine.
6. Check that there are no leaks around the special tool port 

adapters.

7. At the "D" position, measure the hydraulic pressure during 

idling (engine speed: 650 

± 50 r/min).

Standard value: Approx. 0.385 

− 0.525 MPa (56 − 76 

psi)

CAUTION

The throttle should not be fully open for more than five 
seconds.
8. At the "D" position, fully depress the foot brake pedal. Then 

fully depress the accelerator pedal while checking the 
hydraulic pressure indicator, and quickly read the maximum 
hydraulic pressure.

Standard value: Approx. 1.53 MPa (222 psi)

9. Stop the engine.
10.Remove the O-ring from the port plug and replace it.
11.Remove the special tool, and install the plugs to the 

hydraulic pressure ports.

12.Start the engine and check that there are no leaks around 

the plugs.
