Part # 3099222308
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.
