Atomic™ Transmission Controller by MSD®. There is no reason to settle on just three gears or the kickdown linkage of an automatic transmission with the number of electronically controlled four speed automatics that are available these days. MSD will take the mystery out of setting up or programming an automatic trans with the Atomic Transmission Controller. The Atomic Trans Control Module (TCM) is based off the popular Atomic EFI series with the same goal of making installation and setup simple.
- Transmission Harness is required (only transmission specific harness is needed).
- Adjust shift points
- Adjust torque converter clutch behavior
- Select different levels of shift firmness
- Select between auto-shift mode and manual-shift mode
- Activate Dyno Mode to deliver repeatable chassis dyno results
The all-new MSD Transmission Controller was developed completely in-house – evolving from the engineering expertise and proven performance of our Atomic EFI technology. In fact, 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! Doing away with the need for sensor duplication, and an extra programmer, means less wiring for easy installation and a clean appearance. Don’t worry if you haven’t stepped up to an Atomic EFI system yet; the Trans Controller is also offered as a stand-alone system to work with most OEM or aftermarket fuel injection systems, as well as carbureted applications equipped with a stand-alone Throttle Position Sensor (TPS). This allows you to take advantage of modern 4-speed overdrive transmissions and the inherent flexibility associated with electronic controls.
