However, the most common automatic transmissions found in 1993 Chevy trucks were:
* 4L60-E: This was a very common four-speed automatic, used behind many V6 and V8 engines. This is likely the most probable option for many 1993 models.
* 4L80-E: A heavier-duty four-speed automatic, often found in heavier-duty trucks or those with larger engines.
To find out definitively which transmission you have:
1. Check your owner's manual: This is the best source of information.
2. Look at the transmission itself: The transmission case usually has identification markings.
3. Check the VIN: Your VIN number can be used to look up the original specifications of your truck. You can use a VIN decoder online (many are available for free) or contact a Chevrolet dealership.
Once you provide the engine size and model of your truck, I can give you a more precise answer.
