ATF Level Check

NOTE: Keep all foreign particles out of the transmission.

Warm up the engine to normal operating temperature (the radiator fan comes on).
Park the vehicle on level ground, and turn the engine off.
NOTE: Check the fluid level within 60-90 seconds after turning the engine off.
Remove the dipstick (yellow loop) (A) from the transmission, and wipe it with a clean cloth.

If the level is below the upper mark, check for fluid leaks at the transmission, hose and line joints, and cooler lines. If the level is an excess, drain the ATF to proper level.
If necessary fill the transmission through the dipstick hole bring the fluid level up to the upper mark. Always use ACURA ATF-Z1 Automatic Transmission Fluid (ATF). Using a non-Acura ATF can affect shift quality.
Insert the dipstick (A) back into the transmission in the direction (B) shown.
