How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. Notice: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine part or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid. Wait at least 30 minutes before checking the transmission fluid level if you have been driving: Checking the Fluid Level Prepare your vehicle as follows: • 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, run the engine for at least once minute and shift to DRIVE (D). Then shift to NEUTRAL (N) and then REVERSE (R) to fill the hydraulic system. Then, position the shift lever in PARK (P). • Allow the engine to run at idle (500-800 rpm). Slowly release the brake pedal. Then, without shutting off the engine, follow these steps: When outside temperatures are above 90°F (32°C). At high speed for quite a while. In heavy traffic - especially in hot weather. While pulling a trailer. Cold Check Procedure The purpose of the cold check is to determine if the transmission has enough fluid to be operated safely until a hot check can be made. The fluid level rises as fluid temperature increases. DO NOT fill above the COLD CHECK band if the transmission fluid is below normal operating temperatures. 1. 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 and then pull it back out again. 5-31
