    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.

From street and towing to full race, BD Builds Them Best! Your transmission was only designed to handle the torque and horsepower the stock engine delivers, and in the case of some Dodge models, even the stock torque can present a challenge. So when you start adding power modules, turbo upgrades and other bolt-ons, it's only a matter of time before the transmission wears out and eventually fails.

BD transmissions are built specifically to handle the high torque loads of diesel engines at our state-of-the-art transmission facility. We re-program the valve body for higher line pressure, and add heavy-duty clutches with up to 25% more material than stock. The stock thrust washers, which disintegrate and leave metal filings in your transmission, are replaced with roller Torrington bearings. We can upgrade early 47RE transmissions with more rugged 48RE components, even add billet steel input shafts for extreme applications. Each valve body is tested to ensure proper function before we bolt on one of our rigid aluminum transmission pans, which not only adds extra capacity, but reduces case flex. Finally, 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 our Torque Converters and Flex Plates for added performance and strength. Call for details, we'll be happy to answer your transmission questions.

WARRANTY 36-month / 150,000 mile limited warranty on non competitive, racing or sled-pulling applications. BD torque converter must be installed at the time of installation of the transmission - use of a 3rd party or OE converter will invalidate the transmission warranty. See warranty statement for further details

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. We do not offer free shipping on transmissions, however, we do offer a very competitive flat rate charge that is added to your shopping cart at checkout. Further, to aid in returning your core transmission, we give you the option to be billed up front for the core return and we will coordinate the pickup and return of your transmission. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we'll take care of the rest. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

IMPORTANT NOTE: Torque converter is not included with this transmission package.

1030311 Transmission. Installed no problem .Won't go out of park, after the drive shaft was installed. Shifts and drives as it should . Freed the drive shaft and use neutral and the E-brake. Waiting for an appointment at a repair shop for warranty work. Otherwise the transmission works great.

Yes I've got a 93 W350 with the 5 speed Getrag. I'm wanting to replace it with a built auto because I'm just tired of driving standards anymore. My question is if a guy was to buy a automatic from you all would you take in my 5 speed Getrag in on core??

At this time no, we must receive the same unit back.

I have a 1990 dodge Cummins stock hp what trans will work. Do the trans have over dive?

Unfortunately non of the overdrive transmissions will work on your truck without modification. Since your truck has nothing that would make it go into overdrive. It would still be a 3 speed.-Sands

Weren't some of the early Dodge Ram diesels equipped with a 3 speed automatic transmission? I had a 1991 and as I remember, it was not equipped with an overdrive feature. What was the model number of this non-overdrive automatic transmission? Thank you.?

Yes, up until 91(non-intercooled) it would have had a "Diesel" 727 3-speed non-overdrive transmission. -Sands
