Chevrolet transmissions can be manual or automatic. Automatic transmission on a Chevy can be identified in one of two ways: You can look at the size of the pan on the transmission or you can search for the identification number that has been stamped somewhere on the casing. To undertake either method will require you to look under the vehicle.
Move the vehicle to a flat area where you can work, such as your garage.
Raise the front of the vehicle off the ground with a car jack. Lift the driver’s side, then place a jack stand under the frame behind the front wheel and lower the driver’s side of the car onto the jack stand. Repeat this procedure for the passenger side of the Chevrolet.
