DTC P1734:
14-20114-201
12. Turn the ignition switch to ON (II).
13. Clear the DTC with the HDS.
14. Test-drive the vehicle with the shift lever in D, and
let the transmission shift through all five gears.
15. Check for Temporary DTCs or DTCs with the HDS.
Go to step 8.
Go to step 16.
16. Monitor the OBD STATUS for P1733 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 15,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, go to step 8. If
the HDS indicates NOT COMPLETED, go to step 14. Shift Solenoid Valves B or C Stuck OFF
Shift Valves B or C Stuck
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 13.
Replace the ATF (see page 14-232), then go to
step 4.
4. Turn the ignition switch to ON (II).
5. Clear the DTC with the HDS.
6. Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears.
7. Monitor the OBD STATUS for P1734 in the DTCs MENU with the HDS.
Go to step 8.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. If the HDS
indicates NOT COMPLETED, go to step 6.
8. Clear the DTC with the HDS.
(cont’d)Problem in Shift Control System:
Is DTC P1733 indicated?Does the HDS ind icate PASSED? Does t he st r ai ner hav e met al d ebr i s or ex cessi v eclutch mater ial?
Does the HDS ind icate F AILED?

1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
The stall speed tests should be used for diagnostic purposes only.
Stall speed test results should be the same with the shift lever in D, S, and R.
Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the
table.

VSA DTC(s) may come on during the pressure test. If the VSA(s) come on, clear the DTC(s) with the HDS.
1. Make sure the transmission fluid is filled to the proper level (see page 14-231).
2. Raise the vehicle on a lift, or apply the parking brake, block rear wheels, and raise the front of the
vehicle. Make sure it is securely supported.
3. Remove the splash shield.
4. Allow the front wheels to rotate freely.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204). 7. Connect the A/T oil pressure gauge to the line
pressure inspection port (A). Do not allow dust or
other foreign particles to enter the ports while
connecting the gauges.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port with the shift lever in P or N while
holding the engine speed at 2,000 rpm.
NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than P or N.

10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection
port.
11. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and
tighten the bolt to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do
not reuse the old sealing washer.

ATF
NOTE: Keep all foreign particles out of the transmission. 1. Park the vehicle on the level ground.
2. Warm up the engine to normal operating temperature (the radiator fan comes on), and turn
the engine off. Do not allow the engine to warm up
more than two cycles of the cooling fan.
NOTE: Check the ATF level within 60 90 seconds
after turning the engine off. Higher ATF level may
be indicated if the radiator fan comes on twice or
more.
3. Remove the ATF dipstick (yellow loop) (A), and wipe it with a clean cloth.
4. Insert the dipstick into the transmission.
5. Remove the dipstick and check the ATF level. It should be between the upper mark (A) and the
lower mark (B). 6. If the ATF level is below the lower mark, check for
fluid leaks at the transmission, the hoses, and the
line joints. If a problem is found, fix it before f illing
the transmission with ATF.
NOTE: If the vehicle is driven when the ATF level is
below the lower mark, one or more of these
symptoms may occur: The transmission damage.
The vehicle may not move in any gear.
The vehicle may accelerates poorly, and flares when starting off in D, S, and R.
Vibration when the engine is idling.
7. If the ATF level is above the upper mark, drain the
ATF to proper level (see step 3 on page 14-232).
NOTE: If the vehicle is driven when the ATF level is
above the upper mark, the vehicle may creep
forward while in N, or have problems shifting.
8. If necessary, fill the transmission with ATF through the dipstick hole to bring the fluid level to midway
between the upper mark and the lower mark of the
dipstick. Do not fill the fluid above the upper mark.
Always use genuine Acura ATF-Z1 automatic
transmission fluid (ATF). Using a non-Acura ATF
can affect shift quality.
9. Insert the dipstick back into the transmission with the letters ‘‘ATF’’ pointing toward the front of the
vehicle.

NOTE: Keep all foreign particles out of the transmission. 1. Park the vehicle on the level ground.
2. Warm up the engine to normal operating temperature (the radiator fan comes on), and turn
the engine off.
3. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
4. Reinstall the drain plug with a new sealing washer (B).
5. Refill the transmission with ATF into the dipstick hole to bring the fluid level between the upper
mark and the lower mark of the dipstick. Always
use Acura ATF-Z1 automatic transmission fluid
(ATF). Using a non-Acura ATF can affect shift
quality.
6. Check that the ATF level is between the upper mark
and the lower mark of the dipstick.
7. Insert the dipstick back into the transmission with the letters ‘‘ATF’’ pointing toward the front of the
vehicle. 8. If the maintenance minder required to replace the
ATF, reset the maintenance minder (see page 3-4),
and this procedure is complete. If the maintenance
minder did not require you to replace the ATF, go
to step 9.
9. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
10. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
11. Select BODY ELECTRICAL with the HDS.
12. Select ADJUSTMENT in the GAUGES MENU with the HDS.
13. Select RESET in the MAINTENANCE MINDER MENU with the HDS.
14. Select RESETTING THE ATF with the HDS.
NOTE: If you changed the engine oil at the same
time with the ATF, select RESETTING THE ENGINE
OIL LIFE AND ATF with the HDS instead.
Replace.
