LINE PRESSURE ADJUSTMENT

M1231001700402

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: When adjusting the line pressure, adjust 
to the middle of the standard value range.

Standard value: 1.01 

−

 1.05 MPa (Change in 

pressure for a single full of the adjusting 
screw: 0.035 MPa)

4. Install the valve body cover, and then pour in the 

specified amount of ATF.

5. Repeat the hydraulic pressure test (Refer to 

P.23A-152

.) Readjust the line pressure if 

necessary.

SELECTOR LEVER OPERATION CHECK

M1231001300460

1. Apply the parking brake, and check that the 

selector lever moves smoothly and accurately to 
each position.

2. Check that the engine starts when the selector 

lever is in the N or P position, and that it does not 
start when the selector lever is in any other 
position.

3. Start the engine, release the parking brake, and 

check that the vehicle moves forward when the 
selector lever is moved from N position to the D 
position or to 1st or 2nd gear in Sport mode, and 
that the vehicle reverses when the selector lever 
is moved to the R position.

4. Stop the engine.
5. Turn the ignition switch to the ON position, and 

check that the backup lamp illuminates when the 
selector lever is shifted from the P position to the 
R position.
NOTE: The A/T mis-operation prevention 
mechanism prevents movement of the selector 
lever from the P position if the ignition switch is in 
a position other than LOCK (OFF) position and 
the brake pedal is not depressed.
