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. ***

Core Charge Timeline

If the core is returned after 21 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.

Core Return Procedure

Please keep all original packaging of your new item to be used for the core return.
Drain all fluids: oil, fuel, etc. out of the core before it is returned.
Place any plastic plugs or caps received on the new item back onto the core.
To insure UPS, Fed Ex, or USPS will not reject the package due to fuel or oil leakage, please wrap the core in a plastic garbage bag.
Place core inside the box.
If core return paperwork was inside the box, please complete the form and send back with the core.
Please provide a tracking number to [email protected]. Without a confirmed tracking number we cannot guarantee your core refund
If you have questions please call our core department 859-737-4966 ext. 5

Product Details

Product Name: Suncoast E4OD CAT 4, 550 HP TRANSMISSION 1992-1994 2WD (WITHOUT CONVERTER)
Manufacturer: Suncoast
Manufacturer Part #: SC-E4OD-CAT4-9597-2WD-LC
Thoroughbred Diesel Part #: SUNSC-E4OD-CAT4-9597-2WD-LC
Fitment Notes: 1992-1994 Ford Powerstroke

The Category 4

The SunCoast Category 4 E4OD transmission includes our bushing kit, TransGo Tugger Kit, solenoid pack, 45 element intermediate sprag, intermediate band, billet 300 maraging input shaft, billet forward clutch drum, billet intermediate shaft, and dual-load center support.

The Clutch Kit

This new E4OD transmission includes Alto Red Eagle clutches along with Kolene steels.

Red Eagle Friction is the go-to material for most performance applications. The lining has a unique dual-saturation, which imparts high friction coefficients and high heat resistance. Red Eagle clutches are designed to limit the amount of "slip" by providing a shorter lock-up time, generating less heat.

The proprietary process starts with the friction paper saturated in a phenolic resin, cured, and then saturated a second time in a silicate. The silicate imparts high heat resistance.

Red Eagle clutches:

Are designed with a softer, more resilient base paper.
Assure less wear against opposing steel plates.
Reduce the incidence of steel plates burning and warping.

The Intermediate Sprag

The factory sprag in the E4OD transmission unit is notorious for failing when exposed to high levels of fatigue. This could include vehicles exposed to heavy towing or hauling or just higher-than-normal torsional fatigue. These factory sprags are typically 24- or 34-element sprags. In all SunCoast builds, these are replaced with heavy duty 45 element sprags. This is an increase of up to 53% over the factory, offering unmatched performance and ensuring that premature failure does not occur.

Transgo Valve Body Calibration Kit

The valve body is the central nervous system of your transmission. Everything that transpires within the unit begins here. In our SunCoast builds, we exclusively use the TransGo HD2 Tugger Kit. This valve body calibration kit is perfect for exhaust braking and doubles the low clutch holding pressure in manual first gear for reliable downhill braking. You also have the ability to adjust shift firmness to your desired preferences. With the improved converter feed capacity, you benefit with better cooling and lubrication.

Corrects/Prevents/Reduces:

Codes 628, P1740, P1744
Soft shifts
2nd and 3rd burn-up

L/R mod boost valve

New Solenoid Pack

The E4OD is equipped with a solenoid pack that controls shifting from gear to gear. This solenoid pack is comprised of electromagnetic solenoids. The integrity of these solenoids is imperative, as the flow rate and spray pattern could affect shift quality and clutch life. When failure occurs within the unit, it is not uncommon that the same particles and sediments you find in the bottom of the pan are also in the solenoids. This contamination of the solenoids can and will affect the fluid delivery to critical circuits within the unit.

In this SunCoast E4OD transmission, we replace the solenoid pack with a new one to ensure consistent shifts and long clutch life.

New Bushing Kit

As with any standard rebuild, this E4OD transmission also includes a new bushing kit, which also includes a new front pump bushing.

Intermediate Band

This SunCoast Category E4OD Transmission also includes a new carbon fiber band. This band is used in manual second gear and during downshift engine braking. The carbon fiber material in this band is made to withstand a much higher heat range versus the factory material.

The Input Shaft

The input shaft on the E4OD platform has always been the first weak link to bear it's head once additional horsepower is applied. In this Category transmission the factory shaft is replaced with our 300 Maraging Billet Input Shaft.

The Forward Drum Upgrade

The Ford E4OD forward drum has been a sore spot for many E4OD owners for quite a few years. These issues date back to the earlier C-6 and E40D platforms with repeated spline failures and snap ring blow outs. In this SunCoast Category E4OD Transmission the factory forward drum is replaced with a new billet one. The E4OD billet forward drum is manufactured from 4140 heat treated stress relieved billet steel. This new drum corrects and eliminates the common issues with spline failure and snap ring blow outs.

Dual Load Center Support Upgrade

With the SunCoast E4OD dual load center support, the load is now shared with added bronze bearing at the front of the hub. This new bronze bearing stabilizes the loads and eliminates point loading. This improvement in load distribution prevents bearing failure while maintaining improved gear alignment. This is crucial in higher horsepower loads and situations with increased torsional fatigue.

Billet Intermediate Shaft

The Intermediate shaft, also called the center shaft, is the second weakest hard part within the E4OD Transmission next to the input shaft. In this Category E4OD transmission, we upgrade this shaft to a billet one. This new billet intermediate shaft is manufactured from 300m billet steel with upgraded splines. This is an ideal upgrade for diesels exposed to high torsional fatigue and heavy towing. This is a drop-in replacement part with no modifications necessary.
