Plug-in control over shift points, shift firmness, and more. The MSD Atomic Transmission Control Module gives you the ability to adjust the operating parameters of your late model, electronically controlled four-speed automatic transmission. Just plug in the supplied hand-held monitor and you can adjust shift points and the torque converter lockup clutch, choose shift firmness, and toggle between auto-shift and manual shift modes. MSD even includes a Dyno Mode that allows repeatable shifting when testing your vehicle on a chassis dyno. You might also want to consider Allison torque converters as alternatives.
Once installed, the MSD Atomic Transmission Control Module needs only a few basic input parameters to complete the initial setup. Once that is done, you can drive the vehicle and use the advanced setup menu to dial in the transmission in real time. Available data readouts include engine speed, vehicle speed, throttle position, transmission fluid temperature, shifter position, and commanded gear.
The MSD Atomic Transmission Control Module is available as a stand-alone unit that is compatible with most OEM or aftermarket fuel injection systems or carbureted applications that have a stand-alone throttle position sensor (TPS). If you have an MSD Atomic EFI system, there is a version with MSD’s Brainwave system that allows you to seamlessly integrate the module with the EFI system’s ECU. A transmission controller harness is required for the stand-alone system, sold separately.
