    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. 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.

From street and towing to full race, BD Builds Them Best! If you are serious about building power, and simply want the strongest transmission you can put behind your powerhouse Cummins, then the BD Track Master is your end all. Whether you're a serious weekend warrior, or your truck is a trailer queen that tears it up at the track, the Track Master replacement 48RE is built to exceed the standards of even the strongest and fastest at the track.

BD's "Big" fine spline input shaft: This is a completely redesigned input shaft. It is 0.125 thicker than the stock size shaft and includes a hardened billet hub. By increasing the clutch apply piston width BD increased apply pressure, and, by decreasing piston thickness BD was able to install up to 30% more clutch surface.

BD Big Bore, Fine Spline Triple Torque Force Converter (Recommended): You can add one of these awesome torque converters to your new Track Master Transmission for even more holding power. Matching BD's Big bore, fine spline triple Torque Force Converter to the new Big Shaft make them designed for Competition - 550 RWHP (Rear Wheel Horse Power) and above applications. You are required to use a big bore torque converter with the same spline design on this transmission. It does not have to be BD's converter, but it has to have the same shaft size and spline count to work.

By design, OEM transmission Helical gears and engine torque thrusting causes stock plastic and Babbitt thrust washers to melt and break down contaminating lubrication oil and damaging solenoids. BD removes the thrust washers and install roller bearings throughout the transmission which eliminates oil contamination, maintains tolerances, reduces heat and prevents premature solenoid failure.

These transmission packages also include a BD rigid aluminum heavy duty transmission pans which adds extra oil capacity and reduces case flex, plus, includes a BD auxiliary full flow filter kit for extra protection.

Each transmission is dyno-tested to make sure it functions properly in all gears before it is shipped to you in one of our containers.

Other options to consider when replacing your transmission are to mate the BD transmission with one of BD's Torque Converters, as mentioned above, andd Flex Plates for added performance and strength. Call for details we'll be happy to answer your transmission questions.
