The BD Diesel 1031369 is an electronic TapShifter and variable vane exhaust brake integration module engineered for 2005–2007 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.0L Powerstroke diesel and 5R110 TorqShift 5-speed automatic transmission. Designed to bring modern manual gear control and heavy-duty retarding power to the 6.0L platform, this kit combines an OEM-style shift lever featuring +/- tap-shift buttons with a dedicated digital micro-controller and plug-and-play wiring harness. BD Diesel utilizes the factory Variable Geometry Turbocharger (VGT) by commanding the turbo's unison ring and exhaust vanes to close during deceleration, turning the 6.0L engine into a supplemental exhaust brake while giving the driver gear-by-gear tap selection and full torque converter lockup control.

Terrifying brake fade on steep mountain descents, overheated and glazed brake pads and rotors while towing heavy fifth wheels, lack of gear selection on the factory 5R110 column shifter, and annoying transmission gear hunting are what this module eliminates. From the factory, the 2005–2007 5R110 shift quadrant only offers selections for Drive, 3, 2, and 1, leaving the driver with no way to lock out 4th or 5th gear specifically or control manual downshifts smoothly. Furthermore, factory Tow/Haul mode provides only mild engine braking at higher RPM. The BD TapShifter system allows full push-button upshifting and downshifting right from the lever tip, holds selected gears without unwanted PCM upshifts, and instantly activates the turbo's VGT vanes on closed throttle to generate up to 130 retarding horsepower. It is a complete electronic control module, column shift lever, and plug-and-play harness kit only; mechanical exhaust brake butterfly valves, custom transmission tuning, or torque converter upgrades are not required.

It fits 2005–2007 Ford F-250, F-350, F-450, and F-550 Super Duty trucks as well as 2005 Ford Excursions equipped with the 6.0L Powerstroke diesel engine, factory VGT turbocharger, and 5R110 TorqShift automatic transmission.

Disconnect both negative battery cables before beginning installation to protect sensitive electronic control modules. Remove the upper and lower steering column plastic shrouds to access the factory shift lever mechanism, unbolt the factory column lever pivot pin, disconnect the overdrive switch connector, and install the new BD TapShifter lever. Route the shift control harness down the steering column into the under-dash area, securing it away from moving steering shafts, tilt mechanisms, and pedal linkages using the provided cable ties. Mount the digital gear indicator display in a clear line of sight on the instrument cluster surround or lower dash lip. Locate the factory PCM and transmission wiring harness connectors under the hood and behind the dashboard, teeing in the BD plug-and-play harness inline with the factory connectors and routing the VGT control wire to the variable vane turbo actuator solenoid. Mount the main TapShifter electronic control module securely under the dashboard, reconnect the battery terminals, turn the ignition key on, and verify the gear indicator illuminates and steps through gear positions before performing a road test to calibrate closed-throttle exhaust braking actuation.
