Notes

Expanding our transmission control options for our EFI systems, this harness provides plug and play for 2009+ GM 4L60 transmissions using a Dominator. This also contains an internal turbine speed sensor, which was not on the previous models. Additionally, the valve body range selector is wired and controlled differently from the ECU.

Full details on shipping times, returns, warranty and cancellations are on our policy page.
