Current lead times for this product are longer than normal –  Please allow  2-3 weeks for orders to ship at this time.  Sorry for the inconvenience!  

Time to swap out your Camaro or G8’s 6L80e for a 4L80e? Our plug and play harness makes quick work of the wiring required for the swap, and allows you to use an OEM GM Transmission Control Module (included)! Retain all of the great features while tuning with a tuning suite since it is a GM module. Even operates the factory transmission temperature gauge! No reprogramming of ECM or BCM required! Input speed sensor not needed for this kit, do not hook up. This harness does not allow the paddle shifter to work. This harness now supports cruise control!!

Also, if installing in a Camaro, check out our 2010-2015 Camaro 4L80e Conversion Bracket – HERE.

NOTE: Your transmission case must have provisions to run an external shift range switch.  4L80e’s come with two different selector shafts, short and long. You must use the longer shaft to be able to run our kit (they are not difficult to change). The part # is 24235194.

  1. Ken A.

    Easy installation, much easier to dial in transmission tune using HP tuners vs. an aftermarket controller.
