* SM465: This is a manual transmission, but less likely than the automatics. Other manual transmissions were also possible, depending on the specific vehicle.
To know for sure what transmission is in *your* specific 1994 Chevy 5.7L vehicle, you need to check:
* The vehicle identification number (VIN): This will give you the exact specifications of your vehicle. You can usually decode a VIN online using various free VIN decoder websites.
* The vehicle's documentation: Owner's manual or other paperwork might list the transmission type.
* The transmission itself: Look for markings on the transmission case.
Looking under the hood and at the transmission itself is the most reliable way, but you'll need some familiarity with automotive components to correctly identify it.
