NOTE:
 When checking if the transmission will shift to reverse while the wheels are being driven forward,
raise the vehicle on a lift, make sure it is securely
supported, and allow the front wheels to rotate freely.
 Do not release the clutch pedal if you can select reverse gear while the wheels are driven forward.
 When the vehicle is on a lift, and you make the wheels rotate, turn off the VSA system by the VSA
OFF switch.
1. Turn the ignition switch to LOCK (0).
2. Check the No. 3 (10 A) fuse in the under-dash fuse/ relay box.
Reinstallthefuse,thengotostep3.
Install a new No. 3 (10 A) fuse, and recheck. If
the fuse continues to blow, check for short to body
ground in the wire between the No. 3 (10 A) fuse in
the under-dash fuse/relay box and the r everse
lockout solenoid.
3. Test-drive the vehicle.
4. Check for fuel and emissions system’s DTC with the HDS.
Go to the indicated DTC’s troubleshooting.
Go to step 5.

NOTE: When checking if the transmission will shift to reverse while the wheels are being driven forward,
raise the vehicle on a lift, make sure it is securely
supported, and allow the front wheels to rotate freely.
 Do not release the clutch pedal if you can select reverse gear while the wheels are driven forward.
 When the vehicle is on a lift, and you make the wheels rotate, turn off the VSA system by the VSA
OFF switch.
1. Turn the ignition switch to LOCK (0).
2. Try to shift the transmission into reverse.
Go to step 4.
Go to step 3.
3. Do the reverse lockout solenoid test (see page 13-77).
Check the change lever assembly (see page
13-105), if necessary inspect the internal
transmission.
Repair or replace the reverse lockout solenoid
(see page 13-77).
4. Start the engine, and try to shift the transmission into reverse.
Intermittent failure, the system is OK at this
time.
Go to step 5. 5. Turn the ignition switch to LOCK (0).
6. Jump the SCS line with the HDS.
7. Disconnect ECM connector A (44P).
8. Disconnect the r
everse lockout solenoid 2P
connector.
9. Check for continuity between the reverse lockout solenoid 2P connector terminal No. 1 and body
ground.
Repair short to body ground in the wire
between the reverse lockout solenoid and the
ECM.
Check for loose terminals or poor connections
at the ECM. If necessary, update the ECM if it does
not have the latest software (see page 11-227), or
substitute a known-good ECM (see page 11-7), then
recheck. If the symptom goes away with a known-
good ECM, replace the original ECM (see page
11-228).

1. Raise the vehicle on a lift, and make sure it is
securely supported.
2. Remove the filler plug (A) and the sealing washer (B), check the condition of the MTF, and make sure
it is at the proper level (C).
3. If the MTF is dirty, remove the drain plug (A) and the sealing washer (B), and drain it.
4. Install the drain plug with a new sealing washer, and refill the transmission with MTF to the proper
level. Always use Acura Manual Transmission Fluid
(MTF).
5. Install the filler plug (C) with a new sealing washer (D). 6. If the maintenance minder required to replace the
MTF, reset the maintenance minder (see page 3-4).
If it did not reset, go to step 7.
7. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
8. Turn the ignition switch to ON (II).
9. Make sure the HDS communicates with the vehicle and the engine control module (ECM). If it does not
communicate, go to the DLC circuit troubleshooting
(see page 11-204).
10. Select BODY ELECTRICAL with the HDS.
11. Select ADJUSTMENT in the GAUGES MENU with the HDS.
12. Select RESET in the MAINTENANCE MINDER with the HDS.

The PCM turns shift solenoid valve A ON, B and C remain ON, and D and E remain OFF. Shift solenoid valve A
pressure (SA) is applied to the right side of shift valve A. Shift valve A is moved to the left side to uncover the line
pressure port leading to the 1st clutch, and to cover the A/T clutch pressure control solenoid valve pressure port.
Fluid flows to the 1st clutch by way of:
Line pressure (1) Shift valve D Line pressure (1A) Shift valve A Line pressure (1B) Manual valve Line
pressure (5A) Shift valve C Line pressure (5B) Shift valve B 1st clutch pressure (10) 1st clutch
The 1st clutch pressure (10) is applied to the 1st clutch, and the 1st clutch is engaged securely.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

The PCM turns shift solenoid valves B and D OFF, A and E remain OFF, and C remains ON. Shift solenoid valve B
pressure (SB) in the right side of shift valve B is released, and shift valve B is moved to the right side. Shift solenoid
valve D pressure (SD) in the left side of shift valve D is released, and shift valve D is moved to the left side. This valve
movement causes A/T clutch pressure control solenoid valve C pressure port leading to the 3rd clutch.
A/T clutch pressure control solenoid valve C pressure (57) changes to (5J) to be directed to shift solenoid valve D and
to (5K) at shift valve B, and becomes 3rd clutch pressure (30) at shift valve A. 3rd clutch pressure (30) is applied to the
3rd clutch, and the 3rd clutch is engaged securely.
