2011-2019 F250 & F350 6.7L Powerstroke SunCoast 6R140 Category 1 Transmission Rebuild Kit Features:
SUNCOAST CLUTCH STEEL RECIPE W/ FILTER, PUMP BUSHING, GASKET KIT
Kit contains the following:
- All new Carbon Graphitic clutches
- All new custom machined steels
- Improved heavy duty 4-5-6 Overdrive Clutch pack
- Increased overdrive clutch count
- Custom machined Overdrive apply piston
- New Gasket, Seal, & O'ring sealing kit
- New Transmission Filter Kit
- New pump bearing
This kit is a base rebuild kit using the SunCoast clutch and steel recipes along with a new pump bushing which has been an issue for quite some time with the 6R140.
This rebuild kit also includes the filter, overhaul kit, and all the gaskets. This is an ideal kit for someone looking to rebuild a factory stock vehicle with improved frictions and steels to improve longevity in the transmission.
Introducing the 6R140
The new 6R140 from Ford is definitely one of the most exciting drivetrains on the market today. The new 6R140 was released to replaced the previous Torqshift unit, which was the 5R110. The 5R110 was previously used in both the 6.0 and 6.4 Ford diesel engines. When Ford released the 6.7 L Powerstroke powerplant it also released the new much stronger 6R140 Torqshift transmission.
The new Ford 6R140 Torqshift transmission is the most robust transmission Ford has yet to build. This unit was designed and manufactured exclusively by Ford Motor Company. First and foremost, Ford opted to incorporate a robust one-piece bell housing design for the all new 6R140 Torqshift transmission. This new one piece design is not only tough but adds a tremendous amount of rigidity to the case making torsional flex an afterthought. The transmission features a very deep first gear (great for towing and moving mountains) with double overdrive (excellent for 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. So the transmission uses just 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 (a double planetary gearset). The carrier is made up of four pressed components, which are sinter-brazed together to form a rigid, dense structure.
The new torque converter in the 6R140 features an exclusive long travel, ultra high capacity turbine damper designed to soften the extreme force produced by the new 6.7 L PowerStroke. Here at SunCoast we have already improved upon this converter, launching our own line of Torque converters including a variety of stall speeds.
The Pump Bushing
The factory pump on the 6R140 often suffers a loss of lubrication pressure at the converter hub support pump bearing due to failure of the bearing seal. When the bearing itself fails catastrophic failure can and will occur. This new bearing restores normal operation and integrity back to the pump.
The Ford 6R140 platform was designed and built in-house by Ford Motor Company. With a deep first gear (3.97:1), double overdrive, and a one-piece deep skirt case it is easy to see why the 6R140 transmission is such a workhorse.
