This replacement harness connects a Chevrolet Performance LS/LT engine controller package to a 6L80e or 6L90e transmission.
The harness will only work with the Pace Performance 6L80e packages that are custom programmed with proprietary transmission software. You will not be able to hook a standard salvage yard 6L transmission to the Chevrolet Performance controller package with this harness and expect it to work correctly.
