Transmission Fluid Check. Chevrolet Beretta 1996

For 1990-2009 cars

Important: When you check the fluid level, the fluid will be higher on the indicator when the transmission is cold. Conversely, the fluid level will drop when checked at operating temperature. This is due to the case thermostat element.

1. Start the engine and operate the vehicle for 15 minutes or until the transmission fluid reaches an operating temperature of 88°-93°C (190°-200°F).
2. Park the vehicle on a level surface. Apply the parking brake and block the wheels.
3. While the engine is idling and with your foot on the brake, move the shift lever through each gear range, ending in Park.
4. Check the fluid level, color, and condition.
5. If you must add fluid, use DEXRON®-III Automatic Transmission Fluid
