Not only do they fail on trucks with minor upgrades, but even trucks in stock form have been known to be too powerful.

48RE Stage 5 Package, 2003 Dodge 4wd. 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. 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.

It is a very aggressive valve body and a minimum of billet input shaft and flex plate are recommended.

A much more affordable option for Subaru owners
Size: 5 Quart, Style: 1 Pack
When you're paying between $16 & $18+ per quart of Subaru brand CVTF 2 fluid this is a much more affordable option. If you look on the back of a Subaru branded CVTF 2 quart bottle you'll see the Idemitsu logo. Doing this job myself saved me over $1000 on what the dealership quoted me to change the valve body and drain and fill my CVT without skimping on anything.

Same fluid as the Subaru brand
Size: 5 Quart, Style: 1 Pack
This is the manufacturer that makes the Subaru cvt fluid. I used this for the drain and fill on a 2019 Subaru Forester. No problem using a hand pump to fill the transmission. Excellent product will use again to service a 2018 Subaru Crosstrek.
