* 4L60E: A four-speed automatic transmission. This was very common.
* 4L80E: A four-speed automatic transmission, typically found in heavier-duty trucks or those with larger engines.
To know for sure which transmission is in *your* specific 2000 Chevy Silverado 4x4, you'll need to:
* Check the sticker on the driver's side doorjamb: This will list some of the vehicle's specifications, potentially including the transmission type.
* Look at the vehicle's identification number (VIN): A dealership or online VIN decoder can use the VIN to provide detailed information about your truck's specifications.
* Check the transmission itself: The transmission casing will usually have an identification number cast into it.
Without more specific information about your truck, it's impossible to say definitively which transmission it has.
