10R140 CATEGORY 2 BORGWARNER REBUILD KIT WITH EXTRA CAPACITY C, D, E, & F CLUTCH PACKS

Car makers don’t often collaborate on projects, especially when they’re direct competitors. However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R140 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10 speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R140 transmission was advanced enough to handle the power of the Ford F-150, F-250, F-350, F-450, and F-550.

Like it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle, and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance, because the engine has to climb back to the RPMs it was just at. The Ford 10R140 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.

To create this optimal blend of performance and efficiency, the 10R140 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off-the-line. Even though this Ford 10 speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R140 also has three overdrive gears, which it can downshift from very quickly.

10R140 Transmission Gear Ratios

First – 4.70
Second – 2.99
Third – 2.15
Fourth – 1.80
Fifth – 1.52
Sixth – 1.28
Seventh – 1.00
Eighth – 0.85
Ninth – 0.69
Tenth – 0.64
Reverse – 4.87

As shown above this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands. This allows the use of much larger camshafts in a naturally aspirated application. If you are looking into going to a forced induction setup this shift recovery allows for larger turbo and AR housing for max performance.

Newly Designed Thermal Flow Control Filter

This 10R140 transmission has a newly designed filter has two types of 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 oil is colder (higher viscosity) at startup, The fluid will flow through both the fine and course filter media.

As the fluid heats up (less viscosity) , the thermal plate will bend and restrict the coarse media section; directing most of the fluid through the fine media. Therefore catching more of the finer debris once the fluid is heated giving it a far superior filtration system.

This new Suncoast 10R140 rebuild kit comes with a new factory filter to ensure zero flow issues.

Advantages:

• Withstands high horsepower
• Greater torque capacity
• Maintains piston travel
• Optimum performance
• Higher heat resistance
• Smooth engagements
• Enhanced shift feel

The 10R140 Rebuild Kit and its contents 

This is a complete clutch and steel module kit that fits the new Ford 10R140 Transmission. This module kit contains all of the clutches and steels necessary to rebuild your 10R140 transmission. The Ford 10R140 transmission comes standard in the Ford F-150, F-250, F350, F-450, and F-550.

This Suncoast upgraded 10R140 transmission rebuild kit comes with new BorgWarner clutches, steels, factory OEM filter and high performance overhaul kit.

This Suncoast 10R140 rebuild kit contains all the frictions and steels you will to do a clutch and steel replacement on a 10R140 transmission containing a stock count clutches and steels. This 10R140 rebuild kit was designed to be a re-clutch for a stock capacity unit utilizing the BorgWarner frictions and high performance steels. 

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 GM and 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 apply issues.

Installing the drop-in Sonnax main pressure regulator valve kit 105740-12K 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 of these Sonnax features ensure your units will have proper line pressure control through all drive ranges.

• 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 Clip Insert

In listed GM and Ford 10-speed transmissions, heavy linear force solenoids (LFS) are held in place by small spring retainers. These spring retainers are prone to collapse, allowing the solenoid to wobble and become off-center with the inboard valve and damage 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 allows the LFS to be off-center, the pintle cannot stroke the clutch control valve appropriately, compromising the component apply timing and pressure, resulting in shift complaints and converter issues. Valve body damage can also occur if the LFSs remain loose, resulting in valve damage during rebuild.

Sonnax solenoid stabilization clip insert 105740-01K can be used in conjunction with OE spring retainers to secure the solenoids back in place. These solid steel clip inserts force the OE spring retainers to completely fill the casting and solenoid groove gap and prevent the retainers from future collapse. If the spring retainer has already collapsed, the clip insert can be used to reform the retainer to its proper size. Simply place it inside the retainer to expand it to appropriate retention dimensions.

• Prevents future spring retainer collapse
• Reshapes collapsed spring retainers

Solenoid Stabilization Retainer

The heavy linear force solenoids (LFS) in listed GM and 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.

Sonnax solenoid stabilization retainer 105740-19K replaces OE clips and provides 32% more surface area to create more support for the solenoid. Another 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.

• 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
