SOLUTION GUIDE

Selecting the correct Towmaster package depends on your Super Duty's build year and working demands.

The Ford 6R140 TorqShift transmission is a robust six-speed gearbox, but sustained heavy towing and commercial duty cycles can tax factory friction materials and hydraulic circuits. Over time, increased operating temperatures and continuous high-load lockup can induce clutch slippage, flare shifts, and torque converter fatigue. BD Diesel Towmaster packages combine a precision-built transmission with a heavy-duty torque converter to provide the durability needed for heavy work trailers, utility bodies, and fifth-wheel towing.

Because Ford updated hydraulic strategies and electronics across generation breaks, 6R140 transmissions are split between 2011-2016 and 2017-2019 model years. Choosing the generation-matched package ensures proper valve body communication, direct sensor calibration, and smooth integration with factory powertrain management systems.

  • Torque Converter Clutch Shudder

    Factory torque converters can experience clutch slip and shudder under low-RPM, high-load pulling conditions.

    The BD Difference

    The ProForce 2D converter uses a dual surface clutch and machined steel reaction ring for reliable lockup.

  • Elevated Transmission Temperatures

    Continuous heavy towing generates excessive fluid heat that accelerates clutch plate wear and hardens rubber seals.

    The BD Difference

    A BD deep sump oil pan adds fluid capacity to help manage heat under heavy towing.

  • Shift Flare and Delayed Engagement

    Worn friction packs or pressure loss within internal hydraulic passages can cause noticeable rpm flares between gears.

    The BD Difference

    Increased clutch counts and up to 300 PSI line pressure add holding power to prevent flare.

  • Burnt ATF and Debris Accumulation

    Severely stressed factory clutches shed friction material into the fluid circuit, leading to solenoid clogging and erratic shifting.

    The BD Difference

    A brand new valve body and matched converter keep old debris out of the new build.

Does the Towmaster 6R140 package include a torque converter?

Yes, BD Diesel Towmaster packages include a heavy-duty, performance-matched torque converter paired directly with the remanufactured transmission assembly.

What is the primary difference between the 2011-2016 and 2017-2019 packages?

Ford revised electronic controls, internal hardware, and hydraulic calibration between these production spans. You must select the specific package that matches your truck's model year.

Can these packages be installed in both 2WD and 4WD Super Duty trucks?

Yes, the listed packages cover both 2WD and 4WD configurations for the specified Ford F-250, F-350, F-450, and F-550 applications.

How does the electronic line pressure controller work?

The included controller delivers up to 300 PSI line pressure at wide open throttle for up to 76% more theoretical holding power. It only activates when boost is over 15 PSI, unlike solenoid foolers or plugs that are active all the time, so it creates no parasitic load or extra heat when inactive.

Do I need to flush my transmission cooler when replacing the unit?

Yes, thoroughly flushing or replacing the transmission cooler and fluid lines is required to prevent contamination from the failed unit from entering the new transmission.

Do these transmission packages affect vehicle emissions compliance?

These are internal mechanical drivetrain replacement assemblies. However, emissions regulations vary, so review the product page and local guidelines for specific compliance verification.

Is transmission tuning required after installing a Towmaster 6R140?

These units are designed to function with factory transmission control module calibrations, though a proper transmission adaptive relearn procedure must be performed upon installation.
