Here's why a direct swap is unlikely and what potential changes might be needed:
* Transmission Case Differences: Even though they are both 4L60-E's, the transmission cases might have slight dimensional differences that prevent proper mounting to the Caprice's bellhousing.
* Electrical Connectors: The wiring harness connectors for the transmission's solenoids, speed sensors, and other components are likely different between a '92 and '96 model year. This requires significant rewiring or custom connector fabrication.
* Valve Body Differences: The internal valve body calibrations are unlikely to be identical, potentially leading to shifting issues or even damage.
* Torque Converter: The torque converter is specific to the transmission and engine. While it *might* be the same, it's not guaranteed, requiring replacement or careful verification of compatibility.
* Computer Control: The transmission control unit (TCM) is integrated into the car's computer system. A '96 TCM won't be compatible with a '92 system and vice-versa, requiring significant computer reprogramming or replacement.
In short: While a similar transmission might be *used* it will require a significant amount of modification, potentially involving a mechanic experienced with transmissions and automotive electrical systems. It's far more likely to be cheaper and easier to find a used transmission specifically for the '92 Caprice. Trying to adapt the '96 transmission would likely lead to more frustration and cost than it's worth.
