Ensure that the power of your Cummins is getting to the ground with an ATS Transmission Package. The 48RE transmission is the weakest point on a Dodge Cummins truck. Not only do they fail on trucks with minor upgrades, but even trucks in stock form have been known to be too powerful. A heavy duty truck needs parts which can stand up to heavy trailers, stop-and-go commutes to work, or high-horsepower applications. That's why ATS modifies the transmission to make it the strongest and most reliable part of your drivetrain.
With the many shortcomings of the 48RE, none are more important than the clutch packs. This is what takes the power load and transmits it to the rear wheels. ATS transmissions increase the clutch count in the Forward, Overdrive, and Overdrive Brake clutch packs which allow much higher torque capacity in each gear. Clutch material is also essential which is why ATS uses Borg Warner and Raybestos clutches which has both high torque strength, as well as longevity and reliability.
Another important aspect is the hard parts on the transmission. The factory sheet metal strut anchor is replaced with a much stronger billet strut anchor, allowing more precision application of the band. The factory plastic accumulator piston is replaced with a billet unit, as well. The apply lever is a 1:5.0 ratio apply arm, which applies the Borg Warner red lining band. This band features a performance friction material capable of holding higher power levels.
The valve body receives extensive modifications, as well. The ATS valve body has the ability to lock the torque converter in 1st and 2nd gear and circulate transmission fluid in park/reverse/neutral. ATS also machines the TV valve passage and they install their own proprietary TV valve sleeve, and increase the line pressure. You can choose between a towing or a racing valve body. The towing version will deliver smooth, quick, crisp shifts that enhance the drivability and operation of your transmission on the street and attached to a trailer. This is the valve body of choice for a street driven all-purpose truck. The race valve body is their hardcore power build. It is made to sacrifice as little time as possible between shifts, shift hard and fast, and leave nothing behind. It is a very aggressive valve body and a minimum of billet input shaft and flex plate are recommended.
WARRANTY INFORMATION: As with all ATS Transmission Packages, this transmission is covered by a 5 year / 500,000 mile warranty. In order to be eligible for this warranty, all paperwork must be filled out upon installation of the transmission and returned to ATS, to include verifynig line pressure with a mechanical gauge or scan tool.
IMPORTANT NOTE: This Stage 6 Transmission Package comes standard with a Racing Valve Body. If you prefer a less aggressive shift pattern please select the option above to switch to a Towing Valve Body. No additional charge necessary.
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.
