6R140 E CLUTCH DAMPNER ASSEMBLY WITHOUT BILLET SHAFT AND HUB

6R140 "E Clutch" Dampner  

One of the key problems associated with the Ford 6R140 Transmission is a noticeable substantial squawking noise which occurs during the oncoming 4th gear clutch during the 3-4 gear exchange. 

This noise becomes much more prominent when aftermarket friction materials are used inside the transmission for added holding capacity. The aftermarket clutches that are utilizing higher friction coefficients are an absolute must when increasing horsepower and torque or during heavy usage.

The SunCoast patented E-Clutch Damper is the solution to this problem. Using Sound Reduction Absorption Technology, the E-Clutch damper dissipates the unwanted squawk allowing for a clean, crisp, and silent gear exchange. 

This improved design damper will also aide in extending the life of the 4-5-6 clutch pack in the 6R140.

This comes with factory intermediate shaft and hub, for billet upgrade please use part # SC-6R140-ECD-BSH

 

The Engineering

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.
