While the 6R140 is one of Ford's better transmissions, sometimes the 2017-2019 6.7L Powerstrokes paired automatic needs refreshing or replaced, from either over towing, physical damage from time on a trail or flat out abuse. For those looking to replace the factory transmission with something robust, but not focused on race level performance, the SunCoast Guardian HD 6R140 Towing transmission is a fantastic answer for stock non-modified trucks that are looking to increase reliability and longevity.

The Guardian series transmissions are upgraded with SunCoast's custom clutch set. Every one of their 6R140's receives a custom 4-5-6 and 3-5-R clutch pack utilizing custom pistons and apply plates to ensure clean, accurate, and consistent shifts. SunCoast is an American company, doing work in America since 1989. They've taken years of research and development to give you confidence in a reliable transmission for towing and normal operations. As a matter of fact, they carry a 2 year unlimited mile warranty on their Guardian series transmission.

The Ford 6R140 Torqshift transmission is one of the most robust transmissions Ford has yet to build. This unit was designed and manufactured exclusively by the Ford Motor Company. First and foremost, Ford opted to incorporate a robust one-piece bell housing design for the all new 6R140. This single piece design is not only strong but adds a tremendous amount of rigidity to the case reducing torsional flex. The transmission features a very deep first gear great for towing paired with double overdrive for excellent fuel economy. This unit has a total of six forward gears with the ratios as follows: 1st gear 3.974:1, 2nd gear 2.318:1, 3rd gear 1.516:1, 4th gear 1.149:1, 5th gear 0.858:1, 6th gear 0.674:1.

For maximum efficiency, the patented Lepelletier geartrain reduces complexities that exist in connecting an automatic transmission's gear sets and clutches. Simply put, the 6R140 uses a simple gearset to drive a Ravigneaux gearset. As a result of the in-depth development, the transmission uses only five clutch sets to achieve six forward gears. The 6R140 is further strengthened by the utilization of a powder-metal carrier within the compound Ravigneaux planetary gearset which is a double planetary gearset. The carrier is made up of four pressed components, which are sinter-brazed together to form a rigid, dense structure.

Included for the torque converter in the 6R140 is an exclusive long travel, ultra-high-capacity turbine damper designed to soften the extreme force produced by the new 6.7L Powerstroke. At SunCoast, they've already improved upon this converter, launching their own line of Torque converters with a variety of stall speeds.
