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 Details

Product Name:Suncoast 5R110 Guardian 400 HP Towing Transmission (WITH CONVERTER) 2003-2004 4WD
Manufacturer: Suncoast
Manufacturer Part #: 5R110-GUARDIAN-0304-4WD
Thoroughbred Diesel Part #: SUN5R110-GUARDIAN-0304-4WD
Fitment Notes: 2003-2004 Ford Powerstroke 4WD

The GUARDIAN SunCoast 5R110 Transmission is our base 5R110 transmission. This is a perfect transmission for a stock vehicle that is used in heavy duty applications. This offers all of the current fixes for the direct clutch circuit, with our Patent-Pending No Walk center support. This transmission also has the new wide-load direct clutch pack. This is the perfect economical solution for our customers looking for a heavy duty towing transmission with no power adders.

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 five are advertised, with the hidden gear only being used in very cold weather. The five forward ratios are: 3.11, 2.22, 1.55, 1.00, andfinallyoverdrive is 0.71. The TorqShift also utilizes an optional 4th gear at 1.10, which 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 Fords first attempt at adaptive control. The adaptive control shift function monitors the performance over its lifetime and adjusts shift times in real time to ensure consistency and compensate for wear. The TorqShift was also used with the 6.4L. This particular 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 as a result of the fluid flow issues we were seeing and 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.

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 also a larger, wider clutch.

Making the clutch wider effectively increases the mean radius of a clutch, which in turn increases the torque capacity of said clutch. What this means is 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, makes this the most loudly engineered kit on the market today.

Mean effective radius is the distance from the theoretical center of the friction plate to the center of the friction material. What this means is the larger the mean effective radius, the more torque load capacity the friction plate can handle.

What is the warranty on your transmission. How long do I have to get the core shipped back for the core refund? Question how long would it take to rebuild my transmission and do you have a vendor in the Reno Nevada area? Thanks for your time. My number 775-304-1080. Have a good evening.
