Thank you for purchasing the MSD Atomic Transmission Control Module (TCM). MSD is pleased
to announce that this transmission controller was designed with performance reliability, practicality,
and ease of use in mind. Using the correct adapter harness, this unit will plug directly into the factory
connectors on 4L60E/4L70E/4L80E GM transmissions, or the Ford AODE, 4R70W/E, 4R75W/E, E4OD,
and 4R100 transmissions. The Atomic TCM was designed to work as a stand-alone transmission
controller. Programming the transmission controller is done through the handheld monitor, which
eliminates the need for a computer to program the transmission controller.

As with any performance product, please be sure to read the entire instruction manual before
attempting to install this system on your vehicle. Please contract our customer support department
at [phone] if you have any question about installing or operating the transmission controller.

ATOMIC TRANSMISSION CONTROL MODULE INSTALLATION

It is important to select a proper mounting location for the
TCM. The unit can be mounted in the interior or the engine
compartment as long as it is away from direct heat sources.
It is not recommended to mount the unit in an enclosed
area, such as the glove box. When a suitable location is
found, make sure all wires reach their connections. Use the
TCM as a template and mark the location of the holes. Use
a size #20 drill bit to prepare for the supplied self tapping
screws. Assemble the sleeves in the TCM (Figure 1).

Note: Mounting this module near headers or high heat

sources may affect the operation of the TCM.
