Pull the dipstick out and read the fluid level.
When checking fluid at normal operating
temperatures 150˚F-170˚F (66˚C-77˚C), the fluid
level should be within the crosshatched area on the
dipstick. When the vehicle has not been driven, and
outside temperatures are above 68˚F (20˚C), the
fluid levels should be between the holes on the
dipstick.
Adding Automatic Transmission Fluid
Before adding any fluid, be sure that the correct
type will be used. Correct type is shown on the
dipstick.
Add fluid in 1/2 pint (.25L) increments through the
filler tube to bring the level to the correct area on
the dipstick. DO NOT OVERFILL. If the level is
above the top hole on the dipstick, excess fluid
should be removed by a qualified technician.
NOTE: Always dispose of used automotive fluids in
a responsible manner. Follow your community's
standards for disposing of these types of fluids. Call
your local recycling center to find out about
recycling automotive fluids.
