Wait at least 30 minutes before checking the transmission fluid level if you have been driving: When outside temperatures are above 90°F (32°C). At high speed for quite a while. In heavy traffic -- especially in hot weather. To get the right reading, the fluid should be at normal operating temperature, which is 1 80°F to 200°F (82 "C to 93 " C). To check the fluid hot or cold Park your vehicle on a level place. Keep the engine running. With the parking brake applied, place the shift lever in PARK (P). With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). Let the engine run at idle for three minutes or more. Then, without shutting off the engine, follow these steps: To check transmission fluid hot:Get the vehicle warmed up bydriving about 15 miles (24 k ) m when outside temperatures are above 50°F (10°C). You may have to drive longer to bring the fluid to 180°F to 200"F (82°C to 93"C) in colder outside temperatures. See "Automatic Transmission Fluid Temperature Reading" in theIndex. To check transmission fluid cold: cold check is A made after the vehicle has been sitting for eighthours or more with the engine off and is used only as a reference. Let the engine run at idle for fiveminutes if outside temperatures are 50°F (10°C) or more. If it's colder than 50°F (IOOC), you may have to idlethe engine longer. Should the fluid level be low during a cold check, you must perform a hot check before adding fluid. This will give you a more accurate reading of the fluid level. 1.
