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 the 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 dipstick tube, and wipe it with a clean cloth.

If the level is below the lower mark, check for fluid leaks at the transmission, hose and line joints, and cooler lines. If a problem is found, fix it before filling the transmission. If the level is above the upper mark, drain the ATF to proper level (see step 3 ).
If necessary fill the transmission with the recommended fluid through the filler hole (A) to the upper mark on the dipstick. Always use Honda ATF-Z1 Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affect shift quality.
