    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.

The SunCoast Category 68RFE transmission rebuild kits are designed with the goal of solving the issues with the 68RFE transmission in a systematic way. SunCoast carefully considers each deficiency and need before developing these kits. These kits offer you the same recipes that SunCoast uses in their facility when building these units. They strive to provide the most complete series of 68RFE rebuild kits available on the market today, with proven combinations for a successful build.

THE GUARDIAN KIT:
Sometimes when a transmission breaks, the most cost-efficient means of repair is usually a rebuild. SunCoast's Guardian kit contains everything you need to get your 2007.5-2018 or 2019-2024 Ram back on the road after a failure. Including SunCoast's improved Guardian torque converter and billet inner parts, not only will you rebuild, you'll rebuild stronger.

THE SMART TECH DRUM (CATEGORY 1 ONLY):
The new billet clutch housing holds a physically taller clutch pack, allowing the overdrive apply clutch area to increase by 16%. In addition to the increased apply surface area, the thicker clutches and steels increase clutch steel mass by 28%, drastically improving heat dissipation. The new 68RFE overdrive clutch drum also comes with a top bolt-on plate to help eliminate clutch pack flexing and distortion that contribute to premature failure.

THE V2 BILLET DRUM ASSEMBLY (CATEGORY 2, 3 & 4):
The V2 68RFE Billet drum is the most revolutionary advancement for the 68RFE. SunCoast invested extensive research and development into this drum, which can handle over 1,000 horsepower. It addresses overdrive circuit issues while eliminating the common 68RFE squawk. With a 24% increase in hydraulic clamping force, it significantly improves apply time and reduces slip engagement. Additional enhancements include improved overdrive friction elements, a quad-ring O-ring for reliable compression at high RPMs, increased wall thickness for better rigidity, and a redesigned lip seal for enhanced sealing. This fully assembled, drop-in replacement requires no factory parts, ensuring easy installation and superior reliability.

THE 2C PISTON (ALL KITS):
SunCoast replaced the factory piston with an improved billet piece that accommodates an additional clutch, further increasing the surface apply area.

ZERO CAVITATION FILTER KIT (CATEGORY 1, 2, 3 & 4):
This bottom feeder filter kit uses a Torqueflite filter to prevent pump cavitation and allow higher fluid volume. It improves fluid flow under high line pressure and requires a deep aluminum SunCoast pan or a specific OE pan, both included in the kit.

THE HIGH-PRESSURE TUNELESS REPROGRAMMING KIT (CATEGORY 1, 2, 3 & 4):
Designed for increased horsepower and torque, this kit delivers a re-calibrated pressure curve for improved clutch and TCC holding capacity. It features a 30% increase in line pressure, a converter clutch bypass to prevent ballooning, and additional components for enhanced reliability and performance.

THE PISTON REPLACEMENT (CATEGORY 1, 2, 3 & 4):
The Sonnax Accumulator Piston Kit prevents piston-to-bore scuffing and improves durability with its billet aluminum construction and optimized design.

THE DEEP PAN (CATEGORY 2, 3 & 4):
The SunCoast deep aluminum pan adds 4 quarts of transmission fluid capacity, improving cooling and heat dissipation. It features a flush-mounted drain port for easy fluid replacement and is compatible with the SunCoast Zero Cavitation filter kit.

THE TORQUE CONVERTER (ALL KITS):
The SunCoast Torque Converter is engineered for reliability, with features like furnace-brazed fins, hardened turbine splines, carbon-graphitic clutches, and a billet apply piston for precise and consistent lock-up.

THE FLEX PLATE (CATEGORY 3 & 4):
The SunCoast Billet Flex Plate is CNC-machined for strength and designed to flex while preventing cracking. It meets SFI specification 29.3 requirements for safety and durability in high-performance applications.

THE INPUT SHAFT (CATEGORY 3 & 4):
This drop-in replacement input shaft is made from billet 300 Maraging steel alloy for exceptional strength, designed for high power and torque applications.

THE BILLET VALVE BODY PLATE (CATEGORY 3 & 4):
Made from billet aluminum, this plate eliminates warpage and hydraulic cross leaks, addressing common issues like clutch failure and valve body wear.

THE INPUT CLUTCH HUB (CATEGORY 4 ONLY):
Manufactured from 4140 heat-treated billet steel, the input clutch hub provides increased strength at the input shaft spline area, ensuring reliability.

THE SONNAX HD OVERDRIVE CLUTCH HUB (CATEGORY 4 ONLY):
This upgraded clutch hub and shaft are cryogenically treated and shot-peened to reduce crack formation, providing exceptional reliability under high load.
