Network Integration Made Easy
These MSD Transmission Control Modules (TCM) were developed with Atomic EFI technology. The Atomic TCM is designed to integrate directly with the Atomic EFI when using Brainwave so you can modify transmission operation parameters from the same handheld monitor, eliminating the need for sensor duplication and an extra programmer.
Stand-Alone Module: The Transmission Controller is offered as a stand-alone system to work with most OE or aftermarket fuel injection systems and carbureted applications equipped with a stand-alone Throttle Position Sensor (TPS). Designed to control late model GM/Ford 4-speed transmissions with the ease and flexibility of electronic controls. Includes controller, hand-held monitor, and auxiliary harness. Transmission harness sold separately.
