* 4L60E: This 4-speed automatic overdrive transmission was very common in many configurations.
* 700R4: A 4-speed automatic overdrive transmission, though less common than the 4L60E by 1994. It was more likely in lower-output engine configurations.
* SM465: A 4-speed manual transmission. Less common, especially as automatics were becoming more prevalent.
To know for certain what transmission is in *your* specific 1994 Chevy 1500 4x4, you need to:
* Check the vehicle's documentation: The owner's manual or build sheet should specify the transmission.
* Look at the transmission itself: The transmission case usually has an identification tag or casting number that can be used to determine the exact model.
* Check the VIN: A dealer or mechanic can use the vehicle identification number (VIN) to look up the original specifications.
Without knowing your specific truck's configuration, it's impossible to say definitively which transmission it has.
