Description


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. Thats 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. We 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 we use 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. Along with 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. We give the valve body the ability to lock the torque converter in 1st and 2nd gear, circulate transmission fluid in park/reverse/neutral, machine the TV valve passage and install our proprietary TV valve sleeve, and increase 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 our 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.

Answer

The ATS Built 48RE Transmission is built as an improved factory replacement, but not designed as a performance transmission like the ATS Built 48RE Transmission Package’s. The ATS Built 48RE Transmission Package is offered in a number of configurations depending on you applications intended use. For more information on these transmissions, give our Diesel Experts a call at 1-888-DIESEL4!

How much horse power can this transmission hold? Does XDP offer a transmission that can stand up to 1,000 HP?

Answer
Standard ATS Built Transmissions are designed for trucks that are used for light towing, daily driving and stock or slightly modified power levels.

We offer transmissions that fit all HP/TQ needs! As long as the key areas of strength and durability have been addressed, you can withstand those high HP/Torque situations. ATS transmissions, for example, all basically start with the same modifications. Changes in materials are then address as the HP/TQ requirements increase. The difference between a 500HP transmission and a 1,000 HP transmission could often be no more than converting over to a stronger billet internals A billet Input shaft, Output shaft, Intermediate shaft, Flexplate, along with upgraded electronics allow there transmissions to withstand greater torsional loads and absorb the load transfers of power through the transmission, thus increasing reliability. Without these billet shafts, the transmission is at risk for failure during heavy towing/competition use.

ATS offers a number of different level packages on their transmissions. Contact one of our Diesel Experts at 1-888-343-7354 for more information!
