AUTOMATIC TRANSMISSION

23A-41

LINE PRESSURE ADJUSTMENT

M1231108700109

1. Drain the transmission fluid. 

NOTE: The hydraulic pressure test must be performed 
before attempting any adjustments.

2. Remove the valve body cover.
3. Turn the adjusting screw shown in the illustration to adjust 

the line pressure to the standard value. The pressure 
increases when the screw is turned counterclockwise.
NOTE: Adjust to the middle of the standard range when the 
transmission is at the 1st or 2nd gear.

Standard value: 0.98 

− 1.05 MPa (142 − 152 psi)

NOTE: Each complete turn of the adjusting screw changes 
pressure: 0.035 MPa (5.1 psi)

4. Install the valve body cover. Pour in one quart transmission 

fluid.

5. Repeat the hydraulic pressure test (Refer to 

P.23A-26

). 

Readjust the line pressure if necessary.
