Product Description
4L60e to 4L80e Swap Adapter Harness
This adapter is for 1999-2006 vehicles and some 2007's if they have a 13 PIN connector
We also offer an adapter for 2007-2009 (15 pin) with the EXTERNAL Gear Select Switch on the driver side of the transmission as well (click here).
This adapter has a straight connection at the transmission which will generally fit full size truck/SUV applications. If you are swapping a 4L80 into a car or midsize Truck/SUV with tight transmission tunnel clearance, you may need our premium harness (click here) which has a 90* connection at the transmission end of the harness.
This harness allows you to easily swap a 4L80e into a 1999-2006 vehicle originally equipped with a 4L60e/4L65e. The only thing that you will have to do is pin the Input Speed Sensor wiring into the PCM connector and have your PCM tuned for the transmission swap.
