Checking the Fluid Level Prepare the vehicle as follows: 1. Park the vehicle on a level place. Keep the engine running. 2. With the parking brake applied, place the shift lever in P (Park). 3. 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 P (Park). 4. Let the engine run at idle for three to five minutes. Then, without shutting off the engine, follow these steps: 1. Locate the transmission fluid cap which is located next to the radiator hose and below the engine air cleaner/filter assembly on the driver side of the vehicle. The cap is marked TRANS FLUID. See Engine Compartment Overview on page 5-12 for more information on location. 2. After removing the engine air cleaner/filter assembly to reach the transmission fluid cap, turn the cap counterclockwise to remove. Pull out the dipstick and wipe it with a clean rag or paper towel. 3. Push it back in all the way, wait three seconds, and then pull it back out again. 4. Check both sides of the dipstick and read the lower level. The fluid level must be in the cross-hatched area. 5. If the fluid level is in the acceptable range, push the dipstick back in all the way and turn the handle clockwise. 6. Reinstall the engine air cleaner/filter assembly. 5-20
