TRANSMISSION FLUID

Checking automatic transmission fluid (if equipped)

Refer to your scheduled maintenance guide for scheduled intervals for

fluid checks and changes. Your transmission does not consume fluid.

However, the fluid level should be checked if the transmission is not

working properly, i.e., if the transmission slips or shifts slowly or if you

notice some sign of fluid leakage.

Automatic transmission fluid expands when warmed. To obtain an

accurate fluid check, drive the vehicle until it is at normal operating

temperature (approximately 30 km [20 miles]). If your vehicle has been

operated for an extended period at high speeds, in city traffic during hot

weather or pulling a trailer, the vehicle should be turned off for about 30

minutes to allow fluid to cool before checking.

1. Drive the vehicle 30 km (20 miles) or until it reaches normal operating

temperature.

2. Park the vehicle on a level surface and engage the parking brake.

3. With the parking brake engaged and your foot on the brake pedal,

start the engine and move the gearshift lever through all of the gear

ranges. Allow sufficient time for each gear to engage.

4. Latch the gearshift lever in P (Park) and leave the engine running.

5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If

necessary, refer to Identifying components in the engine compartment

in this chapter for the location of the dipstick.

6. Install the dipstick making sure it is fully seated in the filler tube.

7. Remove the dipstick and inspect the fluid level. The fluid should be in

the designated area for normal operating temperature or ambient

temperature.

Low fluid level

Do not drive the vehicle if the fluid

level is at the bottom of the dipstick

and the ambient temperature is

above 10°C (50°F).
