Here's why:
* 4L80E: This transmission was the standard choice for heavy-duty applications, like the Silverado Dually with its diesel engine, in the early 1990s.
* Other options: While there might be rare instances of other transmissions being fitted, the 4L80E is overwhelmingly the most likely candidate.
To be absolutely sure, you should:
1. Check the VIN: The Vehicle Identification Number (VIN) holds the most accurate information about the vehicle's specifications. You can use an online VIN decoder to find out the specific transmission.
2. Look under the hood: The transmission identification tag is typically located on the driver's side of the transmission, near the bell housing.
3. Consult a mechanic: If you're unsure, a mechanic can inspect the vehicle to determine the transmission type.
