The Ford 6R140 platform was developed and constructed by Ford Motor Company. The 6R140 transmission is renowned for its durability and performance, featuring a deep first gear (3.97:1), double overdrive, and a one-piece deep skirt case. Ford added Sinter-brazed gear carriers and a dual media filter to extend service intervals up to 150,000 miles. Additionally, the 6R140 Transmission includes an integrated live PTO with a higher torque capacity than its Allison counterpart, while weighing 25lbs less.

However, there's a chronic issue with the Ford 6R140. Captive clutch failure is common and difficult to address with stock components or traditional methods. Unlike most lockup converters, the 6R140 clutch moves away from the engine block and engages a thin stamped steel backing plate, which is prone to flex and causes clutch failure. SunCoast offers a solution by using a custom rigid backing plate that reduces deflection, improving apply conformity and providing a more durable reaction surface than OE, improving longevity and reliability for years to come.

Another weak point is the OE clutch, which is held together by small, weak leaf springs that are prone to breaking and causing the OE steel clutch plates to damage the cover splines. This problem is particularly frequent in heavy-duty trucks that put massive stress on converter components. SunCoast improves the factory spring system on this 6R140 torque converter with a much more robust system, while also utilizing their ZERO-DRAG technology.

If you're a customer who does a lot of heavy towing or works out of their vehicle, then this new 6R140 torque converter is a perfect replacement for you. It prioritizes reliability, making it an ideal choice for those who need a durable and dependable transmission.

Just Right
Fits just right. The paper filter material seems to be the same quality as the brand name filter I took out with the only percievable difference is price and packaging. One nice thing here is that once taken out of the box, the filter is wrapped in light weight plastic so you don't get the new filter dirty when taking out the old one. Just unwrap it prior to installation for a clean install. Hope this helps.

Same Quality, Cheaper Price!
Fits exactly as it should (2018 Acura RDX) and performs as well as any other brand I've used over the years. Construction and material quality appear as good as (or better) than any other off-the-shelf brand. I have no qualms about using this brand in the future and saving money doing so, compared to other brands.

Worked in RDX 2nd gen
It fit perfect in RDX 2nd gen. The filter built quality looks pretty much like OEM or better. I do not see any performance issue. Price was reasonable. Its a good buy.

DIY!!
Bought this cabin air filter for my 2015 Honda CR-V and it fit perfectly. Installation was super easy and only took a few minutes. I immediately noticed the air coming through the vents smelled cleaner. No need to have it replaced for you. Definitely worth it if you want an affordable replacement that gets the job done.
