    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.

    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.

The Allison 1000 has no doubt proven itself since its mating in 2001 behind the first Duramax equipped GM trucks. Its longevity, even when pushed with moderately heavy loads and higher horsepower have put it at the forefront of transmissions until recently. However, as miles and horsepower accumulate, these transmissions will find their failure points, and ATS has the cure to ensure your horsepower is getting to the ground efficiently.

By increasing the capability of the torque converter, clutch surface area, and line pressure, the transmission can hold 200% more torque than stock. The result is a setup strong enough to handle aftermarket fueling, turbo(s), and tuning, yet is still smooth enough to tow and daily drive with.

ATS Extreme Allison Packages include proprietary modifications to the drums and pistons. ATS has found these modifications necessary when power goes over 700hp at the tires. In addition, the pump is also modified more extensively for increased line pressure. When coupled with the Co-Pilot (standard on all Extreme Packages), line pressure in excess of 300 PSI is achieved - which is needed to prevent clutch slippage.

The Stage 5 features the addition of the ATS Co-Pilot Transmission Controller. The controller dynamically raises line pressure electronically, for additional clamping force on the clutch packs. This prevents slip under high horsepower / high torque situations, such as drag racing, sled pulling or low-speed trailer towing. Shift firmness can be adjusted with the push of a button, so the driver can adjust shift feel in a matter of seconds. The Co-Pilot is designed for trucks at any power level, but becomes crucial at 600+ hp at the tires.

The Stage 5 also includes the ATS Billet Flex Plate and Billet Output Shaft. At power levels over 600hp, the factory flex plate can crack or break. The focus of the ATS Billet Flex Plate is to absorb more torsional load from the crank, thus resisting cracking/breaking as power transfers from the motor to the transmission. In competition applications (drag racing/sledpulling) the stock output shaft can break when launching. ATS includes a billet 300M output shaft to eliminate this point of weakness.

As with all ATS Transmission Packages, this transmission is covered by a 5 year / 500,000 mile warranty.

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.
