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.
One of the weakest points of a 48RE transmission is the stock input shaft. At increased power levels, towing weight or in performance applications, the stock input shaft can break or twist. When this occurs, the transmission will lose movement and can damage the converter, pump and transmission. ATS recommends using a billet input with increased power and/or towing capacity/frequency.
The theory behind a billet shaft is to increase the strength of the material and flex to absorb torsional loads. This allows it to reliably hold increase power levels. ATS' two piece billet input shaft is designed to increase the reliability of the transmission, withstand greater than stock power and torque converter lock-up in sooner-than-factory settings.
While billet shafts are not indestructible, billet 300M material, coupled with stringent design and testing make them far superior to stock input shafts.
Adding a co-pilot or commander to your transmission will put the control at your finger tips. One of the things that many people want to do is have a transmission that they can race on the weekends and still drive it everyday without having to deal with harsh shifts driving on the streets. With the transmission controller, we give you exactly that freedom. During everyday driving, the lower settings will give you smooth shifts during everyday driving, and at the track, the higher settings will give you full throttle shifting that are quick and crisp. Along with this you gain control over your torque converter and can bring it on faster or later depending on your driving style and likes.
ATS billet flexplates are SFI approved, meaning that they stand up to the toughest race application standards. These are crafted out of strong billet steel allowing your transmission to shift faster and harder with out running the risk of breaking the flexplate. The added strain of racing your high horsepower truck is put directly onto the flexplate, giving it much more pressure than the factory settings ever intended. The added strength allows this high-stress situation to be overcome, and transfer all those ponies to the wheels.
The ATS Billet intermediate shaft is part of the back bone of your Dodge Cummins transmission. It is the first hard part to bring power into the transmission and transmit that power to the wheels. With no dampening or power loss other than the torque converter, the shafts in your transmission have a lot to handle. Now add power, weight from a trailer, bigger tires (and is some cases all these things together) and you will be well beyond what that factory shaft was designed for.
The theory behind billet shafts is not quite what you may have in mind. The key to success is not to make the shaft "stronger" necessarily, but give it the ability to absorb more torsional load. The way we do this, is by using billet shafts, they have the ability to rotate further with out breaking. This is going to give the transmission more "give" and allow it to transmit more torque and more load with out breaking.
Along those lines, breaking a shaft can lead to costly repairs
