Is your ride stalling between gear changes or failing to change gears all together? If so, there’s a chance your transmission control module (TCM) is at fault. Working in conjunction with your vehicle’s engine and transmission, the transmission control unit’s primary purpose is to calculate the correct moment for a gear change for smooth and consistently reliable shifting. In addition, it can also send codes to the onboard computer when a transmission malfunction is detected, helping you to diagnose issues as they arise.

American Powertrain Reverse Lockout Modules

American Powertrain reverse lockout modules are safety devices to save your transmission by preventing shifting into reverse on the freeway. These control solenoids communicate with the vehicle speed sensor in the transmission to let them know you are at zero mph so you can safely shift into reverse, rather than using a signal from the brake pedal.

BD Diesel ProTect 68 Trans Pressure Control Kit

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
