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.

Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.
