Ensure that the power of your Cummins is getting to the ground with an ATS Transmission Package. 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. 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 48RE, none are more important than the clutch packs. This is what takes the power load and transmits it to the rear wheels. ATS transmissions 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 ATS uses 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. 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. The ATS valve body has the ability to lock the torque converter in 1st and 2nd gear and circulate transmission fluid in park/reverse/neutral. ATS also machines the TV valve passage and they install their own proprietary TV valve sleeve, and increase the line pressure. The race valve body is their 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.

SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive rate charged at checkout checkout. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we can supply you with a quote on the return shipping as that is not covered in the original shipping cost. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

Adorable and Well‑Made Outfit for Special Events
Color: Light Blue, Size: 10, Color: Light Blue, Size: 10
Got this suit set for my son and absolutely love it. It comes with everything he needs to look sharp, and I really appreciate that it includes both a tie and a bow tie so we can switch up the style depending on the occasion. The quality is impressive for the price — the fabric feels light and comfortable, and the whole outfit has a polished look without being stiff or uncomfortable. The fit was spot on, and the adjustable waistband is a huge help for getting it just right. My son looked great in it, and it’s definitely something he can wear for more than one event. The little details on the jacket and pants give it a classic, dressed‑up feel that works for weddings, holidays, or any special moment. Overall, it’s a stylish, practical set that makes getting him ready so much easier. Really happy with this purchase.

Boys linen fabric suit
Color: Light Green, Size: 16
Boys suit set in a lighter green color. This suit is made with good proportions and seems to fit well. The sizing seems slightly big so maybe size down one size. The fabric does wrinkle easily so be aware that sitting and folding the suit may cause wrinkling. Otherwise it is a very nice suit for a formal occasion. It comes in many good colors.

Nice elegant suit for any occasion.
Color: Light Blue, Size: 12, Color: Light Blue, Size: 12
The suit set is very nice, the fabric material is durable and soft. Overall stitching is tight with nice surging of the hems and great construction on the shoulders. Buttons and button wholes are well done. I'm going to iron in the creases on the front of the pants because they weren't folded properly for shipping. The material does hold on to wrinkles so don't be afraid of your iron to get a super sharp look. The color is a soft baby blue that stands out in a crowd of black suits. With the option of an elastic tie or clip on bowtie this is everything you need to make him look presentable for a variety of occasions. My only complaint about this suit kit is the dress shirt is stiff and thin. I found some loose threads that I don't trust to not get played with. I'll probably trade it out for something with a little more cotton. As far as cost goes mid range, but definitely worth the cost. I might consider something with a vest if it's a super formal event, but I'm very happy with how this suit comes together.

Modern luxury with summer fabric that performs above its price!
Color: Beige, Size: 14, Color: Beige, Size: 14
Wow! My son wore it for Easter Sunday and this suit fits the bill! The linen material is spot on--not too heavy and not too light especially since the weather is warming up now. The jacket is quality made--the design is modern executive, the stitches are strong no flaws to note. The pants are tad bit longer but that's okay, build quality is also great. The white shirt is decent and matches well with the rest of the set. The bow tie and tie itself is a great complimentary to the set, though optional to wear. The whole set just has that quality you would really look for in the price range you would want to pay. Overall, best value for for the, wear right outside the bag, maybe a light ironing otherwise it's perfect! I highly recommend it, no complaints here very happy with this suit!

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out! It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy. The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement. The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort. It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using. Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.
