What else is needed to swap a 2012 Denali 6.2/6L80 (AWD donor) into a 2007 Silverado extended cab?
Here is what the documentation says. Each point links to its source; details depend on your exact computer, harness and transmission.
- On 6L80E swaps the TCM sits inside the transmission, so factory wiring and harness connections clip back into place with no special external controller. (LSX Magazine)
- Gearstar builds each 6L80E to order and gives a deliberately conservative estimate of 500 rear-wheel horsepower. (LSX Magazine)
Confirm against the instructions for your exact parts before wiring. More: Transmission control in our tuning guide.
