We demand a lot of performance out of our trucks these days. Hotter temperatures on highways and in cities, heavier workloads, longer haul times and stretched out maintenance schedules all contribute to the failure of components we've become used to trusting with our livelihood and lives. In a situation where the 10R140 fails in the 2018-2024 Ford Super Duty, trust that SunCoast has a cost-effective solution that was developed and upgraded to perform above and beyond the factory transmission. With upgraded filters, clutch materials and quantity, new hardware and programming, over 30 years of experience is evident in SunCoasts Category 2 offering.
Newly Designed Thermal Flow Control Filter
The Suncoast Category 2 10R140 transmission comes with a new factory filter to ensure zero flow issues. Raybestos Powertrain GPZ friction plates greatly increase transmission performance and durability. This state-of-the-art friction material far exceeds factory material to withstand high stress, high temperatures and repeated cycling. GPZ's outstanding performance benefits is perfect for heavy-duty vehicles and high-stress driving. Testing of GPZ's revolutionary friction material shows that it outperforms factory installed materials by as much as 20%. For a bonus fun fact, its performance improves as the power increases.
Advantages:
- Withstands high horsepower
- Greater torque capacity
- Maintains piston travel
- Optimum performance
- Higher heat resistance
- Smooth engagements
- Enhanced shift feel
The 10R140 transmission, while a very capable unit, has its deficiencies just like anything else when it is asked to perform outside its original design intention. Since its debut, Suncoast has been actively involved in the research and development of upgrades of this newer platform. With SunCoasts active partnership with Raybestos powertrain, they deliver you the best product to date within the 10R140 platform. The Suncoast Category 2 10R140 transmission expanded capacity clutch modules that are included increase the longevity and performance of these 10 speed transmissions.
Suncoast addressed the issue by improving the clutch friction properties with Raybestos GPZ material and increasing clutch capacity by an impressive 20%. This takes the clutch stack from a factory 5-clutch stack up to a 6-clutch stack-up. They simultaneously address heat issues with both improved friction coefficient, as well as increasing surface area. This Suncoast 10R140 transmission "High-Capacity E-Clutch" comes completely assembled and stacked up with a new (not used) OE machined drum, piston and backing plate.
The "E" Clutch
The 10R140 transmission has a pair of troublemakers, the "E" clutch is certainly one of them. The other thorn in your side would be the "F" clutch. The "E" clutch in a 10R140 transmission, is engaged in 1,3,5,6,7,8, and 9th gears. The real issue becomes apparent rather quickly. This clutch is cycled on 3 times and off 2 times by the time you are in 5th gear. The clutch is on in 1st then cycled off in 2nd, cycled back on in 3rd, then back off in 4th...only to be cycled back on in 5th gear. In higher-horsepower or higher-demand towing and hauling situations, this constant cycling on and off can lead to premature failure.
The "F" Clutch
This clutch is also prone to premature wear as has been observed in other Lepelletier Ravigneaux Gear sets. Oncoming clutches in higher gears seem to take the blunt of the beating. With the 0R140 transmission, the "F" clutch is no exception. The "F" clutch is engaged in R,4,5,6,7,8 and 9th gears. The quickest path to early or premature degradation to this clutch pack is wide open throttle or heavy-load-indexed 3rd to 4th shifts. This is especially prominent in applications where torque management has been deleted. Suncoast has corrected this issue by adding 25% more capacity to this clutch pack by adding another clutch to make 5 in this particular clutch pack.
Main Pressure Regulator Valve Kit
Wear in the main pressure regulator bore and on the outboard spool area of the valve is common in listed Ford 10-speed transmissions. This wear minimizes line pressure control resulting in delayed shift engagement, poor shift quality and burnt clutches. Wear at the inboard spool and bore can lead to converter application issues.
By installing a drop-in Sonnax main pressure regulator valve kit, SunCoast eliminates the leakage of line pressure signal oil to exhaust with the incorporation of an extended front valve spool. This valve spool is 270% longer than the OE spool, so actuates in unworn areas of the bore. The O-ringed end plug provides a positive seal and prevents critical signal fluid from leaking to exhaust. Both Sonnax features ensure your units will have proper line pressure control through all drive ranges.
Each Suncoast 10R140 transmission gets this modification to the factory 10R140 Valve Body:
- Extended outboard spool is 270% longer than OE and actuates in unworn areas of the bore
- O-Ringed end plug provides positive seal to prevent critical signal fluid from leaking to exhaust
- Hardcoat anodized aluminum valve combats premature wear
- Drop-in Zip Valve parts install quickly and easily
Heavy linear force solenoids (LFS) in Ford 10-speed transmissions are held in place by small spring retainers that are prone to collapse. When the retainers collapse, the solenoid wobbles in the bore, causing damage to the casting at the clutch valve bore opening. These LFSs actuate by extending a small pintle about .090" to stroke the inboard clutch control valve. When the spring retainer collapses and the LFS is off-center, the pintle cannot stroke the clutch control valve appropriately, resulting in shift complaints and converter issues. Valve body damage can also occur if the LFSs remain loose, resulting in valve damage during rebuild.
SunCoast uses Sonnax solenoid stabilization retainer 105740-19K to replace the factory clips providing 32% more surface area to create more support for the solenoid. Another SunCoast design upgrade is the top of the clip is rolled over to create a positive stop for the flexible side to land against, furthering the prevention of retainer collapse.
Each Suncoast 10R140 transmission gets this modification to the factory 10R140 Valve Body:
- 32% More casting-to-solenoid surface area for better support and leverage
- Positive stop retainer feature to prevent collapse
- Drop-in Zip Valve parts install quickly and easily

Great for Peach Fuzz, But Not as Sharp as I Expected
Size: #14R, Style: Pack of 20
I really liked that each dermaplaning blade is individually packaged, which helps keep them clean and sanitary until you’re ready to use them. As a hairstylist/barber who works with sharp tools every day, I did not feel like these blades were particularly sharp. That may actually be a positive for someone who is new to dermaplaning and wants something a little less aggressive.
I used them on dry skin, but you can also use a facial oil for more glide. They did a nice job removing peach fuzz and left my skin feeling smooth afterward. Just be sure not to use them over active acne or irritated areas.
While they worked well on facial hair, I didn’t notice much additional exfoliation from my first use. I’ll continue using them every couple of weeks and see how they perform over time. Overall, a decent option, especially for removing peach fuzz.

Insightful, Honest, and So Needed
Format: Paperback, Format: Paperback
Debra has a beautiful way of speaking truth with both clarity and compassion. Every book I’ve read or listened to by her has been incredibly practical, insightful, and genuinely life-impacting for me, and People Skills is already proving to be the same.
Reading (or listening) to Debra's books feels like sitting down with both a skilled counselor and a trusted friend. She doesn’t just offer theory, she offers tools. Honest, helpful, and immediately applicable.
One of the ideas that really stood out to me is that relationships don’t run on intentions. They run on skills. We can mean well and still miss the mark. That reminder is both humbling and hopeful.
This book challenges you to stop defending your intentions and start owning your impact. Then equips you with the skills to love better, communicate clearly, and strengthen the relationships that matter most.
If you care about growing healthier, stronger relationships, this book is a gift. I’m already recommending it to friends, and it's one I know I’ll revisit.
