Terms & Conditions for Cores

Many stock replacement parts such as turbos, injectors, injection pumps, and high pressure oil pumps have a core charge that is associated with the new replacement part. You must return the old part to receive a refund on the core charge.

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.
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. If the core is not "like-for-like," your core may not be eligible for return/credit.
You are responsible for core return shipping cost.

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

Thoroughbred Diesel offers defer the upfront core charge when purchasing via credit card payment.

OPTION 1: You can accept the core charge, 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 30 days from the time your order is received. If you return your core after 30 days you may refer to the Core Charge Timeline below as to how you will be refunded.

Core Charge Timeline

If the core is returned after 30 days, 90% of the core will be refunded.
If the core is returned after 60 days, 70% of the core will be refunded.
If the core is returned after 90 days, 50% of the core will be refunded.
After 6 months cores will be accepted at Thoroughbred’s discretion.

OPTION 2: You can defer the core charge. If you defer, you will not be charged for the core at the time of purchase. You will have 21 days from the time your order is received to send the core back. If the core is not received within the 21 days, your credit card will be charged for the core amount on your order. If you return your core after 21 days, you may refer to the Core Charge Timeline below as to how you will be refunded. When Core deferral (Pay Core Charge Later) is limited to payment by credit card only. ***When using PayPal or Affirm as your method of payment “Core Deferral (Pay Core Charge Later)” is not available. The core must be paid at time of purchase. ***

Product Name: SunCoast Category 1 450 HP SunCoast 5R110 Rebuild Kit
Manufacture: Suncoast
Manufacture Part #: SC-5R110SC-1
Thoroughbred Diesel Part #: SUNSC-5R110SC-1
Fitment Notes: 2003-2010 Ford Powerstroke

Tales from the 5R110

The Torqshift 5-speed 5R110 transmission replaces the old faithful 4-speed 4R100 in the 2003 model year with the introduction of the new 6.0L diesel engine. The Torqshift design, in fact, has a total of six forward gears ratios, however only 5 are advertised. The "hidden gear" is only used in very cold weather. The 5 forward ratios are: 3.11, 2.22, 1.55, 1.00, and finally overdrive is .71. The Torqshift also utilizes an optional 4th gear, which is 1.10, that is used in cold start conditions to aid in engine and transmission warm up.

With the Torqshift, once the Tow / Haul mode is activated, it can help increase driver control when towing large loads up and down steep grades. It will also minimize shifts and maximize the available torque. Upon descent, the tow/haul feature utilizes engine braking to help extend the life of the transmission and improves driver control.

The Torqshift was also Ford's first attempt at adaptive control. The adaptive control shift function monitors the performance over its lifetime and adjusts shift times in real time to assure consistency and to compensate for wear. The Torqshift was also used with the 6.4L as well. This transmission was later replaced with the much larger and more robust 6R140 when the 6.7L Powerstroke was released by Ford.

Walking Away from the Center Support. . .

The center support on a transmission is a critical component that could make the difference between success or failure. The center support acts as a stabilizer, just as our lower back and abdominal muscles support us. With the Torqshift being such a long unit, over time the torsional flexing distorts the case, and the center support can sag and become displaced. The Torqshift relies on the center support to also apply fluid feed to the direct and forward clutches. When this distortion occurs, the fluid feed holes for direct and forward can become misaligned. This is especially true when towing heavy loads or under moderate to hard acceleration. This will also lead to premature failure and burnt clutches.

SunCoast has developed a new "No Walk" center support to correct this issue, which we include in this kit. We also go a step further with this and make a new Mag-Hytec pan standard to increase the rigidity of the case and reduce torsional flexing.

With this now being corrected the need for the direct solid modification is no longer needed. We originally created this modification before learning about the torsional effect.

The 'Wide Load" Direct Clutch

The direct clutch pack has been a problem child for some time now. With the center support now being corrected, we move your attention to the most problematic area of the 5R110, the direct clutch. In the 5R110 the direct clutch pack has been the topic of so many discussions. In the beginning we modified the direct clutch solenoid. We did this as a result of the fluid flow issues we were seeing, trying to compensate for what we would later find out was the center support walking. Today many companies still sell these altered solenoids to try to correct a direct clutch issue. We have alleviated this with our new no walk center support.

Moving forward the direct clutch pack is still one of the most abused clutch packs within the transmission. The direct clutch pack is constantly subjected to conditions that can prematurely wear. To alleviate this SunCoast has developed our new "wide load" direct clutch pack. These new clutches are not only made from our SunCoast SCZ carbon graphitic material but a larger wider clutch as well.

Making the clutch wider effectively increases the mean radius of a clutch, increasing the mean radius increases the torque capacity of said clutch. What this menaces the larger the mean effective radius, the more torque load capacity the friction plate can handle.

This new wider clutch is also combined with the new wider steel and new wider apply plate. This combination along with the new and improved "No Walk" center support make this the most loudly engineered kit on the market today.

This is our base recipe less new Ford "9C" transmission pump and all new solenoids that we use on every rebuild. The SunCoast rebuild kit is designed to give the end user an option to build a transmission the SunCoast way using our proven "SunCoast Recipe".

The Input Shaft

The factory Ford input shaft is one of the smallest input shafts on the market today. It's lack of size makes for a sore subject with many of our customers after a simple programmer has proven to be too much. With factory wheels and tires this is a standard replacement for all of our builds. With larger wheels and tire combinations this becomes essential at stock horsepower/torque.

SunCoast uses a new billet input shaft that is heat treated and precision ground from 200 managing steel for maximum held strength. This shaft is a 100% drop in assembly.
