390 MAINTAINING YOUR VEHICLE a minimum of two (2) minutes for the oil to fully drain into the transmission before rechecking the fluid level. NOTE: If it is necessary to check the transmission below the operating temperature, the fluid level should be between the two "COLD" (lower) holes on the dipstick with the fluid at approximately 70°F ( 21°C) (room temperature). If the fluid level is correctly established at room temperature, it should be between the "HOT" (upper) reference holes when the transmission reaches 180°F ( 82°C). Remember it is best to check the level at the normal operating temperature. 7. Check for leaks. Release parking brake. To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. It is normal for the dipstick cap to spring back slightly from its fully seated position, as long as its seal remains engaged in the dipstick tube. Automatic Transmission Fluid And Filter Change It is important that proper lubricant is used in the transmission. Refer to Fluids, Lubricants and Genuine Parts for correct fluid type. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid. CAUTION! Be aware that if the fluid temperature is below 50°F (10°C) it may not register on the dipstick. Do not add fluid until the temperature is elevated enough to produce an accurate reading.
