    Terms & Conditions

    We at Diesel Power Products offer a deferred core program in which we allow you to defer the typical upfront core charge when purchasing via credit card payment. All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, by clicking to agree, you authorize Diesel Power Products to charge you for the core charge.

    All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to, as well as an RMA (Return Merchandise Authorization) number so that you can facilitate the return shipment. When a return label is not included, it is your responsibility to pay for the return shipment; you have the option to pay it directly to your courier of choice or contact us and we can provide a discounted shipping label for an additional charge. DO NOT rely on the return address on the original label as a source for where to ship to.

    If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount.

    Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit. Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. In the event that the core is not "like-for-like," your core may not be eligible for return / credit.

    Diesel Power Products has the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us.

    What is a "Core Charge"?

    In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product. A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. and merely reuses the case.

    Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt. In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.

    If you plan on returning your core you have two options.

    OPTION 1:
    You can accept it, which means you will be charged for the part AND the core at time of purchase. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

    OPTION 2 You can defer the core charge. If you defer it, you will not be charged a core at time of purchase. You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.Core deferral is limited to payment by credit card only.

    What is "Core Return Shipping Cost"?

    This product is remanufactured and requires that your original part being removed (core) to be returned. The return shipping charge of your core is not included in the purchase price of the item, but we offer you a flat rate charge that includes a core return shipping label as a convenience. If you would like a core return label included with your purchase, please select this option.

    Please note that the flat fee is only intended for the contiguous 48 United States. If you are wanting to ship (return) this product from outside of this boundary, please contact us for a shipping quote or expect that we will contact you before processing your order for a shipping quote at which point we will charge the difference if you accept.

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 3 offering.

Newly Designed Thermal Flow Control Filter

SunCoasts 10R140 Category 3 transmission filter has two types of re-designed media: fine and course (medium). The course media is common in most filters (orange filter paper), the fine media filtration (white paper) is the newer material. There is a thermal plate inside the filter that separates the course and fine media. When the transmission fluid is cold (creating higher viscosity) at startup, The fluid will flow through both the fine and course filter medias. As the fluid heats up (decreasing viscosity), the thermal plate will bend and restrict the coarse media section, directing most of the fluid through the fine media. More of the finer debris being caught once the fluid is heated gives the transmission a far superior filtration system. Keeping sediment and contaminates out of the working parts of the transmission.

The Suncoast Category 3 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
Expanded Capacity Clutch Modules

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 3 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.

Pro Loc Valve Body and Pump

With SunCoast's 10R140 Pro Loc valve body, they address several key issues they've have seen in testing concerning the 10R140. This isn't a simple pumping in more line pressure in hopes of ascertaining more clamping force; it’s a multi-faceted approach addressing several key deficancies when exposing these units to more demanding driving environments. These range from heavy towing and hauling to street racing and drag racing.

The factory 10R140 transmission lock-up circuit is an impressive one, in that it can make converter lockup seem somewhat uneventful. The refinement in its engagement is definitely next-level to what we've all been used to. As nice as this feels in reference to NVH (Noise Vibration Harshness), when you start introducing situations where the load demands are testing design limits or performing outside what the vehicle was initially designed for, it can become a huge problem.

In the SunCoast 10R140 Pro Loc Valve Body, SunCoast specifically looked to decrease the time from initial lock-up application to zero turbine slip. In doing so, they change the lockup circuit by replacing the torque converter clutch (TCC) valve increasing lockup holding application fluid pressure. The lockup oil transition time is also improved by modifying critical oiling circuits for the fluid to reach the TCC clutch, resulting in quicker application time, and therefore, reducing TCC clutch degradation. By reducing degradation per application cycle, we all benefit from improved reliability and performance.

Another facet SunCoast addresses is the lube circuit. The lube circuit on the 10R140 transmission is responsible for supplying oil to the planetary gears, clutches, bushings, etc. From the factory, the lube circuit oil is dispersed throughout the transmission as low as 6 PSI. Under normal load demands, this is perfectly acceptable. In more stressful and demanding situations, an increase in lubrication to clutches, steels and planetary gears is critical for removing heat and dealing with the increased load demands.

The SunCoast 10R140 Valve Body specifically addresses this 6 PSI circuit and converts it to a whopping 20 PSI. This is a 250% improvement from the factory calibration, resulting in reduced frictional heat generated. This reduction in heat helps lessen pre-mature failure that can become increasingly evident in high horsepower applications.

Another modification in SunCoast's Pro-Loc Valve Body involves the regulator valve (latch valve) circuit. This oil circuit is responsible for fully engaging the clutches, allowing for full clutch line pressure. In factory form, the regulator valve specifically targeted is responsible for the A, B, C, and F clutch packs. Of course, the primary clutch pack concern is the 'F" clutch, which tends to be the first and most prominent clutch pack failure with the 10R140 in higher horsepower or more demanding environments. In a factory 10R140 valve body calibration, the regulator valve (latch valve) becomes fully engaged, allowing full fluid flow for engagement at 120 psi. When this occurs, the oncoming clutch pack has maximal clamping force. When the clamping force is engaged to max capacity, SunCoast ascertains the greatest static and dynamic holding capacity. In stock form or even mildly modified vehicles, this is perfectly suitable; however, when exposing the vehicle to a more demanding environment, this can be a weak link.

With the SunCoast 10R140 Valve Body they decrease the required pressure to fully engage the regulator to only 80psi. This is a 33% decrease in pressure needed to maximally engage the clutch regulator valve (latch valve) resulting in a quicker shift apply when engaging clutches A, B, C and F. This quicker engagement not only shortens shift times, but it also decreases the heat resonating in the clutch pack, preventing premature degradation and extending clutch life. To improve this shift calibration even more SunCoast is evacuating non-critical oil to increase application rate.

The factorys overall line pressure is modified in the SunCoast pump/valve body combo. SunCoast increases overall main line pressure by as much as 60psi. The additional line pressure not only increases maximal clamping force of the individual clutch packs but increases overall pump volume production. To reduce the potential for runaway pressure and the over-compression of clutch fibers, the SunCoast 10R140 Valve Body does have a built-in bypass, dumping excessive pressure above 420psi.

Features & Benefits of Pro-Lok:
  • Increased Line Pressure, as much as 60psi
  • Increased clamping force on all clutch packs
  • 250% Increase in Cooler Charge Pressure
  • Increased Lock-up Apply Pressure
  • 33% Decrease in Maximal Pressure Actuation of Clutch Packs
  • Shortened Shift Times
  • Improved Clutch Wear
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
Solenoid Stabilization Retainer

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 leading to 32% more surface area for 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
