4L70E- designed to attach to an LS engine. The 4L70E features either a 15 or 17-pin main harness connector. You will need to verify the pin count if this is going into a factory application, and plan to use the factory computer. If this is not going into a factory application, you will need to use a standalone transmission controller.
