Checking
With the car on level ground, pull the transmission
dipstick and check the level of fluid immediately after the
engine is shut off (within one minute).
The fluid level should be between the full and low marks.
Push the dipstick all the way in to check the fluid level.
If the level is at, or below, the low mark, add Honda
Premium Formula Automatic Transmission Fluid or an
equivalent DEXRON-II type automatic transmission fluid.

Bring the transmission up to operating temperature
by driving the car. Park the car on level ground, turn
