SUNCOAST CLUTCH STEEL RECIPE W/ 4-5-6 DAMPENER, FILTER, PUMP BUSHING, GASKET KIT
Kit contains the following:
This rebuild kit includes the filter, overhaul kit, and all the gaskets, along with a Guardian Torque Converter. 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 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.
When SunCoast first took a look at the 6R140 Torqshift transmission we instantly saw the similarities between the the Ford 6R80 and GM 6L80/6L90 platforms. We new from previous experience the 4-5-6 clutch pack would be the first area that needs to be addressed. The 4-5-6 clutch pack is also known as the "E CLUTCH" and is one of the smallest clutches in the transmission. As we tested our different friction materials and manufactures we saw a pattern develop. The higher the friction coefficient the more violent the shifts become, especially when adding additional torque is in the equation. Often times this creates the 3-4 "squawk" when shifting into 4th gear.
It became very apparent that if we were going to deliver a superior fiction material to our customer, this issue would need to be addressed. We have seen our competitors simply settle for a clutch that has less friction coefficient allowing slip to occur during the shift. while settling on an inferior friction material may be acceptable to some, Ron and the SunCoast development team took a different approach. We decided to take a more scientific approach, and yet another Patent hangs on the wall. . .
The Patent and the Dampener
The 6R140 E clutch hub is designed without any dampener. This makes perfect sense due to the fact that Ford designed the 6R140 Torqshift transmission with the thought process that there would be torque management. With torque management in place we are defueling during shifts essentially pulling the power between shifts. Ford has also designed this with a certain torque limit in mind that most certainly did not have deletes, larger chargers, and aftermarket tuners involved. Couple this along with the removal of torque management and you have created a situation where failure is imminent.
SunCoast has designed a completely new 4-5-6 clutch hub that incorporates a damper assembly that also uses a Sound Reduction/Absorption Technology that eliminates the dreaded squawk and restores shift quality. This new clutch hub damper allows for clean, crisp, and silent gear exchange. This allows us to use much more sophisticated friction materials with higher friction coefficients ensuring longevity and reliability.This new Patented SunCoast E Clutch Hub Damper has seen over 1,000hp reliably. It is only available at SunCoast.
SunCoast has also developed a new 4-5-6 "E" clutch power pack using nine of our custom frictions. This new proprietary SunCoast clutch pack is exclusively designed for our patented clutch hub. This custom SunCoast set-up provides a very clean and crisp shift. The extra capacity in the clutch pack along with the higher friction coefficient provides unmatched performance that cannot be matched by anything else on the planet.
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.
