After starting off in reverse gear, the PCM turns shift solenoid valve A ON, B and E remain ON, and C and D remain
OFF. Shift solenoid valve A pressure (SA) is applied to the right side of shift valve A to cover the A/T clutch pressure
control solenoid valve A pressure port, and to uncover the line pressure port leading to the 4th clutch creating full line
pressure. The 4th clutch is engaged securely with line pressure.
When R is selected while the vehicle is moving forward, the PCM commands shift solenoid valve A to turn OFF, and E
to remain OFF. Shift solenoid valve A pressure (SA) is not applied to shift valve A so that line pressure (3A) is not
applied to the servo valve. Also shift solenoid valve E pressure (SE) is not applied to shift valve E so that line pressure
(3’) is not applied to the servo valve. The servo valve cannot be shifted to the reverse position, and hydraulic pressure
is not applied to the 4th clutch from the servo valve for reverse; as a result, power is not transmitted to the reverse
direction.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

When the vehicle speed increases, the PCM sends a signal to A/T clutch pressure control solenoid valve A to increase
A/T clutch pressure control solenoid valve A pressure (55), and the lock-up control valve is moved to the left by the
increased pressure. Then torque converter pressure (94) from the left side of the torque converter is completely
released at the lock-up control valve, and torque converter pressure (91) engages the torque converter clutch securely;
the torque converter clutch is in full lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

 No. 2 (ORN): Shift solenoid valve B
 No. 3 (RED): Shift solenoid valve E
 No. 5 (BLU): Shift solenoid valve A
 No. 8 (YEL): Shift solenoid valve D
15. If the resistance is within the standard, go to step 17 and check the solenoid valve for a clicking
sound. If the resistance is out of standard, go to
step 16.
16. Disconnect the shift solenoid valve connector, and measure the resistance at the solenoid valve
connector. Replace the shift solenoid valve if the
resistance is out of standard, then go to step 20.
17. Connect a jumper wire from the battery positive terminal to the shift solenoid wire harness
connector terminals, and connect another jumper
wire from the battery negative terminal to body
ground individually. A clicking sound should be
heard.
 If a clicking sound is heard, the valves are OK, and the test is complete, connect the connector.
 If no clicking sound is heard, replace the shift solenoid valve (see page 14-217). 18. Replace the shift solenoid harness if the test results
are OK.
19. Install a new O-ring on the shift solenoid wire harness connector, and install the connector in the
transmission housing.
20. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
21. Check the shift solenoid wire harness connector for rust, dirt, or oil, then connect the connector
securely.
22. Refill the transmission with ATF (see step 5 on page 14-232).
23. Install the battery tray, the battery base, and the resonator.
24. Install the air cleaner assembly (see page 11-345) and the intake air duct (see page 11-348).
25. Do the battery installation procedure (see page 22-69).
26. Install the splash shield.
