You'll have a heavy-duty, reliable transducer when you install BD Diesel valve body electronics upgrade kits. One of the leading causes of faults with automatic transmissions is failed governor pressure transducers, especially if you run higher line pressures. These kits replace the stock plastic transducer with a sturdy metal unit that can handle greater line pressures without failing; preventing over-pressure codes and wild oscillations, thus extending transmission life.

BD Diesel TorqLoc systems will allow your torque converter to work at maximum efficiency. They feature three different converter settings. The manual setting allows you to manually lock up the converter. The stock setting transfers control of the converter lockup back to your vehicle's OEM computer. The AutoLoc setting locks up the converter when the exhaust brake is activated, allowing 100 percent of the retarding forces to be transferred to the rear wheels. This setting eliminates clutch slippage under heavy torque loads, reducing transmission temperature and extending transmission life in the process.

The Holley Sniper Transmission Controller (STC) is designed for common GM and Ford electronic 4-speed automatic transmissions. Three part numbers cover a complete range of applications—all Sniper EFI systems, Sniper 2 EFI-specific (M8 CAN connection), or a full standalone unit. The Sniper specific applications connect to your Sniper EFI system via CAN bus and are programmed through the existing Sniper 3.5 in. touch screen. No programming is available with PC computer software; however, the transmission functions can be data-logged and reviewed with Sniper PC software. The Standalone version includes a dedicated 3.5 in. touch screen and is primarily intended for carbureted engine combinations. GM and Ford 4-speed electronic overdrive transmissions are simple in operation. They have four speeds, with the top gear being an overdrive; and all have a lockup torque converter that eliminates any slippage when the lockup is applied. With a stock torque converter, the lockup should only be applied under light throttle conditions or excessive wear will occur. Upshifts, downshifts, and torque converter lockup are based on vehicle speed and throttle position (or optionally the MAP sensor) and are adjustable with the 3.5 in. touch screen. P/N 551-100: Replacement controller unit only P/N 551-101: Controller unit and power harness only P/N 551-102: Standalone kit for carbureted applications (includes power harness and hand-held programmer) P/N 551-103: Controller unit and power harness for use with Sniper 2 EFI systems Holley Sniper Transmission Controller features: * Adds electronic transmission control functionality to a Sniper 2 * Controls conventional electronic 4-speed transmission applications.

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.

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

BD Diesel ProTect 68 Trans Pressure Control kits deliver 150 percent of the torque-holding force to stock transmissions like no others can. The industry-leading exclusive custom valve body separator plate and gaskets substantially reduce cross leaks compared to stock and other applications, even with much higher line pressures. An Electronic Pressure Control module delivers up to 250 psi clutch-apply pressure at full throttle, providing 150 percent of the holding force to prevent clutch slippage. All of this without modifying the transmission pump or removing the transmission. These controllers dynamically adjust the hydraulic-apply pressures, based on turbo boost/engine load. No tuning is required. Installation takes 2 to 3 hours to complete without having to do a full transmission relearn—since no internal tolerances have changed. A "fresh" stock transmission will have the ability to handle up to 500 hp. For higher power or demands, a complete BD 68RFE transmission with additional clutches and new designed components is recommended. Order the kit tailored to your vehicle. Product features: * 56 percent more theoretical holding power * Custom bonded gasket valve body separator plate increases line pressure while stopping internal cross leaks * Heavy-duty accumulator plate to prevent blowout * Dynamically adjusts hydraulic-apply pressures based on turbo boost/engine load * Dynamic control ramps up the much larger sweep * Prevents clutch slippage * No full transmission relearn required; quick relearn suggested * Warranty on parts: 12-month/24,000 miles

BD Diesel pressure transducer adapters allow you to use a more rugged and reliable sensor/transducer. Older transmissions utilize a metal model, while a lower quality plastic model is used in later models—and this can create problems on transmissions running higher line pressures. These adapters allow late model transmissions to use a sturdier metal sensor. They're plug-and-play with no soldering or splicing required. The adapters have built-in electronic circuits that convert the sensor pressure signal to the correct range—and even stops fault codes in applications running higher-than-stock line pressures.

ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions. Additional product details: * Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction, and low wear rates * Carefully broached splines provide exact fit onto the transmission input shaft for long spline life and better clutch release * Heavy-duty torsional dampening springs are provided in the best sizes and spring rates to help reduce noise * Drive plates are made of high-carbon steel; heat-treated and black zinc coated to resist bending, cracking, fatigue, and rusting * Certified to SFI specifications
