SKU #: ATS-3099142326 ATS 3099142326 Stage 1 Transmission Package 07.5-09 6.7L Cummins 68RFE 4WD

While the 68RFE transmission has been a far superior transmission to any of the previous offerings from Dodge, its shortfalls have ultimately reared their ugly heads. On top of this, the 68RFE is heavily computer controlled, which means that when stall rates and other necessary items are upgraded, the factory computer gets which can lead to the immediate demise of what should have been an upgraded transmission. The professionals at ATS have determined how to properly upgrade the 68RFE to ensure its longevity under any circumstances.

ATS started RD in 2007.5 and spent countless man hours and resources re-designing and strengthening the platform. This began with building their Five Star converter for the transmission. It features a billet cover, five square tab lock-up clutches, billet stator, furnace brazed impeller, billet piston and HD bearings - all stalled to the Cummins torque curve. Capable of handling 2500 ft/lbs of torque, this torque converter will handle whatever is thrown at it.

The ATS Stage 1 68RFE Package is designed for stock up to 550 rear wheel horsepower. Without aftermarket TCM tuning (typically available as an option with custom tuning devices such as EFILive) this transmission will be limited to supporting 400-450 rear wheel horsepower. With the addition of transmission tuning, capability is increased to 500-550 rear wheel horsepower.

Torque Converter Regular Valve Upgrade - The Torque converter regulator valve has been redesigned to prevent over pressure and ballooning of the converter. This also regulates minimum converter charge for proper cooling and lubrication of the transmission gear set. This redesign eliminates the common problematic valve and bore ware that is usually the first cause of high mileage transmission failure.

Pump Upgrade - The main pressure regulator circuit is modified to enable a broader range of pressure that can be commanded from the Co-Pilot. This allows the pump to lower line pressure when the engine is at low loads and more responsively raise pressure above stock to react with increased engine torque and horse power levels.

Low Sprag Upgrade - Next, ATS removed the plastic low sprag and replaced it with a metal clutch. Due to physical limitations inside the transmission, there is no way to make it physically larger. However, ATS bypasses its use when paired with the Co-Pilot, thus eliminating failures between 1st and 2nd gear.

Reinforce the Forward and Intermediate Shaft Hubs - A common failure on the 68RFEs are cracked shaft hubs. Even with stock power, the hub can begin to crack near the point it meets the shaft. ATS reinforces this area to avoid torsional stresses that can cause catastrophic transmission failure. This is a standard on all ATS 68RFE packages.

Reinforce the Rear Planet Pinions - Modified power or towing frequently can cause the rear planet pinions to loosen and cause catastrophic transmission failure. ATS reinforces the pinions to prevent any movement of the pins - thus eliminating failure from the factory design.

• The Under Drive (Forward) clutch pack surface area is increased by 21%, using single sided clutch plates.
• The Over Drive clutch pack surface area is increased by 17%, also using single sided clutch plates, this allows for better clutch control when overdrive is used at higher power levels.
• The 2C clutch pack surface area is increased by 34%, using double sided frictions.
• The 4C clutch pack surface area is increased by 34%, using double sided frictions.

Valve Body Upgrade - The 68-RFE uses a non-synchronous, clutch-to-clutch design. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve a flawless shift. Because of the sensitivity of the hydraulic circuits, ATS heavily modified many areas of the valve body. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity. The accumulator plate is made of high-grade material to compensate for the additional pressure that the accumulator pistons and springs exert during heavy power situations.

Deep Pan and Eliminating Case Flex - All ATS 68RFEs come with a deep pan. The pan adds extra fluid, features an aluminum-finned design, magnetic drain plug and is tapped for a temperature probe. One of its most important benefits is that it adds rigidity to the case. 68RFEs are known to have excessive case-flex, which results in a cracked bellhousing, tailshaft or main section.

A broken case, bellhousing, tailshaft housing, shafts or planetary/sun gears are not covered under the ATS warranty. Please consult the ATS Transmission Warranty for specific details.

SHIPPING POLICY - PLEASE READ - 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. For this reason, we cannot offer free shipping on transmissions. However, we do offer the option to pay for return shipping up front. If you select this option once your core transmission is ready to be picked up, you just need to give us a call with your original order number and the core tag on the transmission, and we'll take care of the rest. As always, if you have any questions, give us a call or send us an e-mail.
