Direct OEM Replacement Module

This Transmission Control Chassis Control Module carries part number 242345035235 and matches interchange 591-07270. It fits 2005-14 Hummer, Saab, Saturn and GM vehicles including Buick, Cadillac, Chevrolet, GMC, Pontiac and many listed models. The unit is a direct factory original for a single replacement.

Used Unit From Legacy Stock

The module comes from an 80 year old auto parts inventory that included NOS and used items stored out of public view. It replaces one factory original module when the original has failed or been damaged. The jump is worth it only when a verified part-number match confirms compatibility with the specific vehicle.

Simple Swap With Correct Verification

Installation is a straight swap once the part number 242345035235 is confirmed against the vehicle VIN and the original module label. What usually goes wrong is ordering without checking the interchange 591-07270, leading to a module that fits the year range but not the exact platform or calibration.
