Make sure the rubber cap on the dipstick fits in the dipstick guide and that you push the dipstick in all the way.

If you are not sure how to add fluid, contact your dealer. Use only Acura ATF DW-1 (automatic transmission fluid). Do not mix with other transmission fluids. Using transmission fluid other than Acura ATF DW-1 may cause deterioration in transmission operation and durability, and could result in damage to the transmission. Damage resulting from the use of transmission fluid other than Acura ATF DW-1 is not covered by the Acura new vehicle warranty. 524
