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.

The Ford AOD transmission is a popular upgrade for older vehicles that originally ran 3-speed transmissions. When you want to get rid of lugging in third and fourth gear then you'll need TransGo input shafts. These hardened shafts work with cast iron or stamped steel drums, and allow one to run a custom high stall or stock C6 converter with the AOD giving it open converter performance. Not only will this get rid of the lugging but they will also take care of coast down chug. Your 2-3 and 3-4 shifts will be softer with the open converter setup, but you can firm them up if you so desire with TransGo's AOD-HP Reprogramming kit (TRG-AOD-HP). When you want to get the most out of your AOD transmission then go with TransGo input shafts.

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

Torque converters are considered one of the most mysterious mechanical components in today's vehicles. They function like a clutch, and keep the engine running even when the vehicle comes to a halt. By designing the stall speed to match both the engine and desired stall speed, ACC Performance converters help low-end idle speeds, improve performance, and acceleration. ACC Performance Products has emerged as an out-right leader in torque converters and here's why: * Boss Hogs are welded, not furnace-brazed; furnace brazing is not the best way to adhere torque converter components, it will erode and ruin the stators and all rotating parts * Industrial Torrington bearings handle more torque than smaller, uncased needle bearings * Aircraft aluminum washers instead of fiber washers put more horsepower and torque directly to the ground * ACC converters are hand-built and tested to ensure that you get the best converter money can buy * With returns below one percent, you are assured of the highest quality parts available * Street Bandit converters are designed to handle as much as 650 hp * Custom-engineered turbine hubs maintain the highest quality, strength, and durability * Stators are built with high-flow vents and channels for greater cooling to handle greater power and higher temperatures * Engineered with a single bolt pattern that makes ACC converters surprisingly light to free up your motor and allow it to gain rpm quicker Notes: * Boss Hog Street Bandit torque converters are not designed to handle the extreme shock and abuse of nitrous oxide or trans-brakes * It is imperative that a transmission cooler be added with any torque converter that is rated over stock stall speed

The ideal GM TH400 upgrade for any power level, Sonnax heavy-duty forward drums (34554-01) feature a unique combination of high-strength, light weight, and a cutting-edge design to optimize transmission performance. Racing applications quickly push the heavy, cast-iron OE drum over its limits, with failure most common at the weak point where the shaft and drum connect. The problem can be addressed with a larger spline and lighter-weight aftermarket aluminum drum—but durability becomes a huge issue with wear of the clutch splines, shaft spline connection, and seal ring bore. To dramatically reduce weight and deliver the ultimate in reliability, the Sonnax high-strength, chromoly steel drum is custom-engineered with several lightening features for a low rotating mass. It weighs 3 lbs. less than the OE drum and is just 3 oz. heavier than a common aluminum drum. Weight is reduced carefully, without compromising strength, by ribbing the front of the drum, adding clutch splines (28 vs. 14) and lightening holes, plus reducing the diameter inner section of the drum at the middle seal ring area. This versatile drum upgrade has an oversized 28-tooth shaft-to-drum spline and can be used with a variety of input shaft styles. This includes Sonnax 1 in. diameter, 30-spline heavy-duty input shaft 30280-02, Sonnax 1 1/8 in. diameter, 35-spline big input shaft 35280-02, and other aftermarket shafts with 28-spline connection between shaft and drum: * Ultra-modern drum delivers both high-strength and light weight for unrivaled performance at any power level * Compatible with Sonnax and other aftermarket 28-spline input shafts * Optimized for use with rubber clutch separators for applications with clean neutral setups * Clutch spline major diameter is reduced slightly, and two sets of full-length clutch splines added to back up clutch separators * Lightening holes correspond to input speed sensor locations in aftermarket cases for more accurate converter and shift data * Middle seal is eliminated—an aluminum clutch volume spacer kit 34554-11K is available separately for applications in which clutch fill/drain time may be a concern * Sonnax high-RPM checkball capsule 57510-01 is installed to eliminate pressure drop at high (5500+) RPM, a common problem with OE and other aftermarket checkballs
