Before attempting the swap:
* Identify the transmission codes: This information is usually found on a tag on the transmission itself, or in the vehicle's documentation.
* Check for differences: Even if the codes match, compare details like bellhousing bolt patterns, output shaft length, and any electronic connectors.
* Consult a repair manual: A repair manual specific to the 1993 and 1996 Suburban models will provide detailed information on transmission compatibility.
In short, while it *might* work, you need to do your due diligence to verify compatibility before undertaking the swap. A simple code match isn't sufficient. A mismatch could lead to serious mechanical problems or even damage to the vehicle.
