Ford 6R140 TorqShift

6R140 TorqShift Transmission Specs & Ratios

The 6R140 was Ford's "clean sheet" transmission design that replaced the 5R110W in Ford's diesel powered Super Duty. Made in the USA, the 6R140 is loaded with heavy duty features, including a high capacity filtration system, "Live Drive" power take off, low speed torque converter lockup, double overdrive speeds, and a rigid 1 piece case. Using the SelectShift manual shift mode, users can place the truck into "M" and manually shift the transmission through all 6 gears via "+" and "-" buttons mounted on the shift lever, particularly useful in poor weather, high load driving conditions. With low speed TC lockup, a driver is able to lug the 6.7L Power Stroke down to 900 rpm. The transmission is found in trucks with a GCWR of up to 50,000 lbs.

The 6R140 is standard behind Ford's 6.7L Power Stroke turbodiesel and the only available transmission - a manual transmission option has never been offered with this engine. The transmission features a patented dual media transmission filter that allows for relatively long service intervals. The gear spread provides a favorably low 1st gear to maximize available torque at low speeds and a relatively high overdrive ratio to minimize engine rpm for greater fuel economy at cruising speeds.
