ATS started R&D in 2007.5 and spent countless man hours and resources re-designing and strengthening the platform. This began with building our 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. ATS offers various stages to the 68RFE platform to meet certain power levels and uses. Contact ATS to discuss which stage transmission would be best for you. All ATS 68RFE Packages come backed with a 5 year / 500,000 mile warranty. The ATS Stage 1 68RFE Package is designed for stock to 550hp trucks. Without TCM tuning or the H&S Overdrive Software, this transmission can hold 400-450hp at the tires. With the addition of transmission tuning, capability is increased to 500-550hp. For those using the H&S Overdrive Software, any line pressure setting can be run EXCEPT the 250 PSI setting. Contact ATS to discuss transmission tuning in more detail. The Stage 1 includes:

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, we 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, we bypass 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 reinforce the pinions to prevent any movement of the pins ? thus eliminating failure from the factory design. Clutch Pack Upgrade For power levels over 400hp, the clutch packs need to be addressed.

ATS built 68RFEs feature extensive machining to the pressure plates to add: ? 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 At this point, we needed to look at the valve body and build it around the ATS Co-Pilot
