Call or Text (352) 722-52956R140 coolers and parts for the 2011-2014 Ford 6.7L Powerstroke
The 6.7L runs two separate coolant loops, each with its own radiator, thermostat and degas bottle. On 2011-2014 trucks the transmission cooler sits on the low-temp secondary loop, alongside the intercooler and fuel cooler. Let that loop run low on coolant and the trans cooler gets starved, which pushes temperatures past the 195 to 230 degrees F the 6R140 is meant to see. An auxiliary cooler addresses that low-temp-loop limitation.
Cooling hardware
Mishimoto offers the MMTC-F2D-11SL transmission cooler, listed for 2011-2016 6.7L trucks, plus universal transmission fluid coolers in several sizes, a heavy-duty cooler with its own fan, a heavy-duty fluid cooler and a universal transmission and power steering cooler. BD Diesel adds the Xtruded auxiliary trans cooler, a double-stacked Xtruded cooler and a universal electric cooler fan. The Mishimoto cooler is listed by year for your truck; universal coolers are mounted and plumbed by the installer, so measure the space first.
Shift quality and pressure control
Harsh shifts, a 2-3 flare and ratio codes trace back to valve-body debris sticking the 1-2-3-4 control valve, an eroded TCC boost valve bore and dead solenoids that cross-leak. Fluid and filter service comes first. Past that, this collection carries the SPE Motorsport S100128 6R140 solenoid body, BD's 6R140 pressure controller, its LED kit and a pressure enhancer solenoid, and the ATS Diesel Performance 6R140 Co-Pilot Tow Edition.
Sensors, lines and hard parts
An Alliant Power transmission fluid temperature sensor and 2-wire pigtail cover the wiring side, and SPE adds a 6R140 transmission line kit and a rear cover. For high-power builds, the ATS billet intermediate shaft is here, because stock shafts can crack at the turbine spline once power climbs well past stock. BD also offers interlocking pressure plate kits in full and partial versions. A Mahle transfer case gasket covers 4x4 trucks.
Fitment notes
Most 6R140-specific parts here are listed 2011-2019. The Mishimoto 6.7L cooler and the BD full interlocking pressure plate kit are listed 2011-2016, and the Alliant temperature sensor covers 2003-2014 6.0L, 6.4L and 6.7L trucks. The 10R140 that arrived for 2020 shares no converter or valve-body parts with the 6R140. Universal coolers fit many trucks, so confirm space and fittings. Verify by VIN.
Frequently asked questions
Do I need an auxiliary transmission cooler on a 2011-2014 6.7L?
If you tow, it is worth a look. These years cool the transmission on the low-temp secondary loop, and an auxiliary cooler addresses that limitation. Keep the secondary coolant full either way, because low coolant there starves the trans cooler.
Will a new solenoid body cure harsh shifts?
It can be part of the fix. Dead solenoids cross-leak and, together with valve-body debris and a worn TCC boost valve bore, cause harsh shifts and a 2-3 flare. Do a fluid and filter service first, then look at solenoids and the internal harness.
Who needs a billet intermediate shaft?
Trucks built for high power. Stock input and intermediate shafts can crack at the turbine spline once output climbs well past stock. A stock or near-stock truck does not need one.
