How do I know what transmission my Chevy truck has?

How to Identify the Transmission in Your Chevy Truck
To determine the type of transmission in your Chevy truck, you can follow these steps:
1. Check the VIN (Vehicle Identification Number): The VIN can provide useful information about your GM vehicle, including the model, series, engine type, engine displacement, and even the type of carburetor that were originally installed. You can refer to a GM VIN decoder guide to learn how to read the VIN number for your specific vehicle.
2. Consult with an Auto Parts Store or Mechanic: You can visit an auto parts store or consult with a mechanic. They can use the information obtained from the hood, engine, and VIN to locate the type of transmission available for your particular truck.
3. Look for the Transmission Code: Open the driver’s side door and find the white card on the side of the door filled with small black lettering. This card contains specific details about the year the car was made, its transmission, engine specifications, and other details. Look for a 3-character code starting with “M” on the card, which corresponds to the transmission code. You can then match that code to a table to find the specific transmission type.
4. Inspect the Transmission Pan: Another method is to look at the size and shape of the transmission pan. Automatic transmissions on Chevy vehicles can be identified by the size and shape of the pan. You can compare the shape of the pan to diagrams to determine the type of transmission on your vehicle.
Remember, if you’re unsure or need more specific information, it’s always a good idea to consult with a professional mechanic or refer to the vehicle’s manual for accurate and detailed information.
