MSD Atomic transmission control modules are designed to adjust the operating parameters of later model electronically controlled 4-speed automatic overdrive transmissions. They're simple to configure with the supplied hand-held monitor--no PC required. You now have access to adjust shift points, adjust torque converter clutch behavior, select different levels of shift firmness, select between auto-shift and manual shift mode, and activate dyno mode to deliver repeatable chassis dyno results. The included hand-held monitor connects to them and can be left in place as a dashboard to monitor the transmission in real time, or can be disconnected when the configuration is complete. Once installed, these modules need only a few basic parameters to complete the initial setup. First, select the type of transmission you are using--all supported transmission types are listed in the menu. Other required fields include the number of engine cylinders, rear-end gear ratio, and tire height. Once this has been completed, you can now start and drive the vehicle, while taking advantage of the advanced setup menu items to dial-in the transmission to your liking. You can feel the results in real-time as a passenger manipulates the parameters and monitors the real-time data. Data available for viewing includes engine speed, vehicle speed, throttle position, transmission fluid temperature, shifter position, and commanded gear. Best of all, the MSD Atomic transmission control modules are available as completely stand-alone units or Brainwave-compatible for the Atomic EFI systems. A transmission controller harness is sold separately.

Bowler Performance All-in-One transmission wiring harnesses for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up, you will be able to connect via Bluetooth to your Apple or Android smartphone using Bowler's free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The perfect finishing touch for any Tremec T-56 Magnum conversion, Bowler's All-in-One harnesses eliminate the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. Previously, you would have needed up to five separate parts to perform all the same functions wrapped one of these harnesses. The more technology we incorporate into our hot rods sometimes requires specific input signals to allow everything to function correctly. With the two speed outputs available in these harnesses, you can independently control the output of each one further eliminating any need for additional equipment and connections. Regarding the reverse lockout, Bowler has incorporated the same speed setting feature as the OEs into the All-in-One harnesses, giving you better control over when the lock out is triggered. Bowler's All-in-One harnesses give you much greater flexibility in the components you are able to use and require less time wiring everything up, providing an easier solution for setting up your Tremec T-56 Magnum transmission. Choose the harness version designed for your specific transmission make. Additional notes: * Harnesses utilize a small, built in, epoxy sealed box that will control each of the three functions with power and grounding for each function through a switched +12 V circuit and a wire connected to the negative battery post or engine block. * Control of the reverse lockout solenoid is based on a user defined speed setting (default is set at locked above 4 mph and unlocked at 0 to 3 mph), eliminating the need for a separate lock-out control box. * For your electronic speedometer, the harness is equipped with two speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 V, varying in frequency as the speed changes. * Output will automatically shift and give you 0 to +10 volts for EMC input needing positive only signal. * The two speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want, and are able to drive any common speedometer, cruise control, or ECM. * Tremec T-56 Magnum reverse lock-out module VSS with dual output, pre-set as GM 40-pulse output on one and 16-pulse output on the other and can be adjusted with your iOS or Android device. * Includes wiring for reverse lights, reverse lock-out, and vehicle speed sensor.
