    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, 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. 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.

The factory Ford 5R110 suffers from weak points in the converter, clutch pack assemblies, valve body and line pressure limitations. These weaknesses arise when the motor's power is increased or in towing applications. ATS addressed these concerns by re-designing the torque converter, transmission pump, valve body and clutch packs. The result is a solid transmission setup to meet the demands of your Ford Super Duty. Ensure that the power of your Powerstroke is getting to the ground with an ATS Transmission Package.

By increasing the line pressure, clutch pack surface area and modifying the valve body, the 5R110 becomes a consistent, responsive and dependable transmission. The Stage 3 adds a billet 300M input shaft and billet flex plate. As power increases over 400hp, or considerable weight will be towed, the input shaft and flex plate take the brunt of it. The ATS billet components are designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use. The ATS Stage 3 5R110 is designed for trucks that see daily driving and towing duties, aggressive tuning, and a modified turbo and/or injectors.

ATS transmissions are backed by a 5 year / 500,000 mile warranty - regardless of power level or use.

SHIPPING POLICY - PLEASE READ - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. For this reason, we cannot offer free shipping on transmissions. However, we do offer the option to pay for return shipping up front. If you select this option once your core transmission is ready to be picked up, you just need to give us a call with your original order number and the core tag on the transmission, and we'll take care of the rest. As always, if you have any questions, give us a call or send us an e-mail.

Thank you for the review and glad you like the new trans. We'll arrange to have your core picked up.

How much horsepower and torque is this rated for??

ATS does not rate their transmissions by horsepower. We make recommendations on what you have done or are planning on doing to your truck. Also what you do with your truck. If you have a 600 hp daily that doesn't tow we would recommend one trans, if you have a 600hp truck and you tow everyday. We are going to recommend a different transmission. DppSands


How much gears has it got?

Same as factory. 5 forward speeds and 1 reverse. DppSands


Would you recommend this for 1000HP+ daily driver/ weekend drag machine??

I would recommend something a little heavier then that transmission for 1000hp. I would rate that transmission at about 700hp. DppSands


What does defer mean when checking out for core charge??

Hi Dylan We give the option to defer the core charge. Which means you have a 21-day grace period from when you receive the product to send the core back. As long as we get it within the 21 days, you do not get charges a core. If it takes longer than 21 days, the core charge is charged to the card on file. Not to fret, you can still send it back, and get refunded. -Ben


Can I send my transmission to be built and get my (same) transmission back? If this is possible, what is the turn around time??

Yes, that can be arranged. Time line is as follows: -Ship time from you to ATS (approx 3-5 business days) -Tear down and build time at ATS (approx 2-3 weeks) -Ship time from ATS to you (approx 3-5 business days) To arrange this please call in and speak to one of our sales techs. -Ben
