As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve D ON, A remains ON,
and B, C, and E remain OFF. Shift solenoid valve D pressure (SD) is applied to the left side of shift valve D. Shift valve
D is moved to the right side uncovering the A/T clutch pressure control solenoid valve C pressure port leading to the
5th clutch. The PCM controls the A/T clutch pressure control solenoid valves to regulate hydraulic pressure. A/T clutch
pressure control solenoid valve B pressure (56) changes to 4th clutch pressure (40) at shift valve B. A/T clutch pressure
control solenoid valve C pressure (57) changes to (5L) at shift valve D and to (5N) at shift valve B, and becomes 5th
clutch pressure (50) at shift valve A. The 4th and 5th clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

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.

As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve E ON, and shift
solenoid valve E pressure (SE) is applied to the right side of the lock-up shift valve. The lock-up shift valve is moved to
the left side to switch the torque converter pressure port (91), which goes to the right side of the torque converter, and
torque converter pressure port (94) is released from the left side of the torque converter. Torque converter pressure
(91) flows to the right side of the torque converter to engage the torque converter clutch. The PCM also controls A/T
clutch pressure control solenoid valve A to regulate A/T clutch pressure control solenoid valve A pressure. A/T clutch
pressure solenoid valve A (55) is applied to the lock-up shift valve and the lock-up control valve. The position of the
lock-up control valve depends on A/T clutch pressure control solenoid valve A pressure (55) and torque converter
pressure released from the torque converter. The lock-up control valve controls the amount of torque converter clutch
lock-up until fluid between the clutch piston and the torque converter cover is fully released; the torque converter
clutch is in partial lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

29. Reconnect all connectors.
30. Update the PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
31. Test-drive the vehicle with the shift lever in D at speeds over 20 km/h (12 mph), and let the
transmission shift through all five gears.
32. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the output shaft (countershaft)
speed sensor and the PCM. If the PCM was updated,
substitute a known-good PCM (see page 11-7), then
go to step 31. If the PCM was substituted, go to step
1.
Go to step 33.
33. Monitor the OBD STATUS for P0723 in the DTCs MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 32,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the output
shaft (countershaft) speed sensor and the PCM. If
the PCM was updated, substitute a known-good
PCM (see page 11-7), then go to step 31. If the PCM
was substituted, go to step 1. If the HDS indicates
NOT COMPLETED, go to step 31. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF (see step 3 on page 14-232) through a strainer. Inspect the strainer for metal debris or
excessive clutch material.
Replace the transmission, then go to step 12.
Replace the ATF (see page 14-232), then go to
step 4.
4. Test stall speed in D (see page 14-210).
Go to step 5.
Shift valves A and D are stuck. Repair these
valves and the hydraulic circuit, or replace the
transmission, then go to step 12.
5. Measure the line pressure (see page 14-211).
Go to step 6.
Repair the ATF pump and the regulator valve,
or replace the transmission, then go to step 12.Problem in 1st Clutch and 1st
