10. Measure the ATF temperature sensor resistance between shift solenoid wire harness connector
terminals No. 6 and No. 7.
If the resistance is within the standard, install the shift solenoid wire harness and a new O-ring in
the transmission, then go to step 13.
If the resistance is out of standard, go to step 11.
11. Disconnect the connectors from the shift solenoid valves, and replace the ATF temperature sensor/
shift solenoid harness assembly (F) and the O-ring
(G) with new ones.
NOTE: The ATF temperature sensor is not available
separately from the shift solenoid wire harness.
12. Connect the shift solenoid valve connectors: BLU wire to shift solenoid valve A.
ORN wire to shift solenoid valve B.
GRN wire to shift solenoid valve C.
YEL, WHT, and WHT wire connector to shiftsolenoid valve D.
RED wire to shift solenoid valve E.
13. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
14. Check the connector for rust, dirt, or oil, clean or repair if necessary, then connect the connector
securely. 15. Refill the transmission with ATF (see step 5 on page
14-232).
16. Install the battery tray, the battery base, and the resonator.
17. Install the air cleaner assembly (see page 11-345) and the intake air duct (see page 11-348).
18. Do the battery installation procedure (see page 22-69).
19. Install the splash shield.
Replace.

ATF Level Check

B
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.

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.
