* 4L60E: This 4-speed automatic was very common.
* 4L80E: This heavier-duty 4-speed automatic was used in higher-payload or heavier-duty models.
To know for sure which transmission is in *your* specific 1997 Chevy Silverado, you need to check:
* The vehicle identification number (VIN): A VIN decoder can provide detailed information about your truck's specifications, including the transmission. Many online VIN decoders are available.
* The vehicle's paperwork: Your owner's manual or other documentation might specify the transmission type.
* The transmission itself: You can sometimes find a tag on the transmission casing that indicates the model number. However, this requires getting under the vehicle.
Without more information about your specific Silverado (engine size, trim level, etc.), it's impossible to definitively state the transmission size.
