* 4L60E: This is a 4-speed automatic transmission, and was very common in this year and model.
* 700R4: A 4-speed automatic, less common than the 4L60E but still possible depending on the engine and options.
* SM465: This is a 4-speed manual transmission.
To know for sure which transmission is in *your* specific truck, you need to:
1. Check the vehicle identification number (VIN): The VIN contains information about the truck's specifications. A decoding website or a dealer can help decipher this.
2. Look under the truck: The transmission's case usually has identification markings cast into it. This is often easier with the truck on a lift or ramps.
3. Check your owner's manual (if you have it): The manual will specify the transmission type for your specific truck.
Don't rely solely on assumptions; always confirm the transmission type before purchasing replacement parts.
