Product Details

The MSD 2771 is a dedicated transmission controller wiring harness designed specifically for 2009 and newer GM 4L70E automatic transmissions. This harness serves as the essential connection between the MSD Atomic Transmission Control Unit (TCU) and the transmission, enabling full electronic control over your 4-speed automatic.

Part of the MSD Atomic transmission control system, the 2771 harness is engineered to provide a precise, direct-fit connection with the proper wiring connectors matched to the 4L70E's factory plug locations. It is sold individually and designed for use exclusively with the MSD Atomic TCM (part #2760).

Key Features:

  • Designed exclusively for 2009 and up GM 4L70E transmissions
  • Connects the MSD Atomic TCU to the transmission for full electronic control
  • Direct-fit wiring connectors matched to the GM 4L70E transmission
  • For use with MSD Atomic Transmission Control Module (TCM) — Part #2760
  • Emissions Code 5: Legal for sale or use on emissions-controlled, non-emissions-controlled, and racing-use-only vehicles
  • Made in the USA

The MSD Atomic transmission control system allows enthusiasts to easily tune and modify the operating parameters of their GM 4-speed automatic transmission. The 2771 harness is the correct harness for 2009 and later 4L70E applications — for 2006–2009 GM 4L70E transmissions, use MSD part #2770.
