The 47RE 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 47RE, 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 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 1:3.8 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.

This ATS Automatic Transmission carries a FIVE YEAR/FIVE HUNDRED THOUSAND MILE (5 yr/500,000 mile) Warranty. This Warranty shall not apply to any automatic transmission that has been improperly stored or installed This Warranty shall not apply to misapplication, improper operating conditions, accidents, or neglect. This Warranty shall not apply to an automatic transmission that has been improperly repaired, maintained and/or altered by the owner or his agent/tech. Most importantly, all transmission shafts are not covered by this Warranty on any transmission due to the capability of certain situations to cause stress-loads beyond the structural ability of the shaft. ATS’ Automatic Transmission Warranty is NOT transferable. It is mandatory for implementation of this warranty that line pressures are tested at time of install. ATS will not pay for any fluids replaced in the event of a transmission failure.
