Flip the handle up, pull out the dipstick, and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds, then pull it back out again. 4. If the fluid level is in the acceptable range, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place. 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 minutes or more. Then, without shutting off the engine, use the steps that follow. How to Add Automatic Transmission Fluid Refer to Recommended Fluids and Lubricants on page 11-12 to determine what kind of transmission fluid to use. Using a funnel, add fluid down the transmission dipstick tube only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It does not take much fluid, generally less than 0.5 L (1 pt). Do not overfill. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading.
