6. Remove the harness clamp (C) from its bracket (D).

7. Remove the ATF temperature sensor (E), and replace the sensor.

8. Install the new O-ring (F) on the new ATF temperature sensor, and install the ATF temperature sensor.

9. Check the connector for rust, dirt, or oil. Connect the connector securely, and install it on its bracket.

10. Install the harness clamp on its bracket.

11. Refill the transmission with ATF (see step 6 ).

12. Install the splash shield.

ATF LEVEL CHECK

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 longer than the time it takes for the radiator fan to come on twice.

3. Remove the dipstick (yellow loop) (A) from the dipstick guide tube, and wipe it with a clean cloth.

NOTE:

Keep all foreign particles out of the transmission.

NOTE:

Check the fluid level within 60-90 seconds after turning the engine off.
Higher fluid level may be indicated if the radiator fan comes on twice or
more.

6. If the level is below the lower mark, check for fluid leaks at the transmission, and hose and line joints. If a

problem is found, fix it before filling the transmission.

NOTE:

If the vehicle is driven when the ATF level is below the lower mark one or
more of these symptoms may occur:



Transmission damage.



Vehicle does not move in any gear.



Vehicle accelerates poorly, and flares when starting off in D and R.

7. If the level is above the upper mark, drain the ATF to proper level (see step 4 ).

8. If necessary, fill the transmission with the ATF through the dipstick guide tube opening (A) to bring the

fluid level midway between the upper mark and lower mark of the dipstick. Do not fill past the upper
mark. Always use Acura ATF-Z1 Automatic Transmission Fluid (ATF). Using a non-Acura ATF can
affect shift quality.

9. Insert the dipstick back into the dipstick guide tube.

ATF REPLACEMENT

1. Warm up the engine to normal operating temperature (the radiator fan comes on), and turn the engine off.

2. Raise the vehicle on a lift, or apply the parking brake, block both rear wheels, and raise the front of the

vehicle. Make sure it is securely supported.

3. Remove the splash shield.

4. Remove the ATF filler bolt and drain plug (A), and drain the automatic transmission fluid (ATF).



The engine vibrates at idle.

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 shifting problems.

NOTE:

Keep all foreign particles out of the transmission.

NOTE:

If a cooler cleaning is done, refer to ATF Cooler Cleaning (see ATF
COOLER CLEANING ).
