Includes: Billet Input Shaft, Billet Flex Plate, Five Star Torque Converter, built 68RFE transmission, Reinforced Overdrive, Underdrive hubs, and Compound Planetary Assembly, Deep Transmission Pan, Reinforced forward hub and shaft, Reinforced intermediate shaft and hub, Modified pump, Modified valve body. ATS started 68RFE in 2007.5 and spent countless man hours and resources re-designing and strengthening the platform. This began with building 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 4 68RFE Package is designed for 600+ rear wheel horsepower. Exclusive to the Stage 4 is the ATS Billet Input Shaft for the 68RFE. The factory input shaft can fail power levels in the high 500\/low 600hp range. Early in the 68RFE's development, ATS addressed this weak point by developing a billet 300M input shaft (U.S. made shaft). ATS has seen this shaft withstand nearly triple the factory power output of the 6.7L Cummins. The result has been increased reliability - even with torque converter lock-up in 2nd gear. Stock flex plates become a liability when power exceeds 500hp. To cure this, ATS Stage 4 transmissions come equipped with an SFI-Approved flex plate. The ATS Flex Plate is designed as a direct replacement to the factory unit. Factory crankbolts and OEM spacer are re-used on the ATS Flex Plate.\u003c\/p\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\n\u003cul\u003e\n\u003cli\u003eHigh Volume Pum\u003c\/li\u003e\n\u003cli\u003eHeavy Duty Gear Train\u003c\/li\u003e\n\u003cli\u003eHandles High HP Applications\u003c\/li\u003e\n\u003cli\u003eIncreased Transmission Torque Capacity\u003c\/li\u003e\n\u003cli\u003e300m Steel Shafts\u003c\/li\u003e\n\u003cli\u003eIncreased Diameter of Steel Shafts\u003c\/li\u003e\n\u003cli\u003eLaser-Cut Clutch Packs\u003c\/li\u003e\n\u003cli\u003eMultiple Clutches in Clutch Packs\u003c\/li\u003e\n\u003cli\u003eIncreased Transmission Lubrication\u003c\/li\u003e\n\u003cli\u003eSingle Sided Friction Clutch Services\u003c\/li\u003e\n\u003cli\u003eApply More Power through Clutch Services without Burning Up\u003c\/li\u003e\n\u003cli\u003eEvenly Distributes Torque Between Clutch Services\u003c\/li\u003e\n\u003cli\u003eEnamel Coating Painted on to Prevent Corrosion\u003c\/li\u003e\n\u003cli\u003eRecomended Use with ATS Co-Pilot for Products Full Potential\u003c\/li\u003e\n\u003cli\u003eATS Five Star Viskus Clutch Drive Torque Converter:\u003c\/li\u003e\n\u003cli\u003eProduct Made in America\u003c\/li\u003e\n\u003cli\u003ePantented Viskus Clutch Drive System\u003c\/li\u003e\n\u003cli\u003eBillet Cover with Patented Square Flank Drive\u003c\/li\u003e\n\u003cli\u003eIncreased Oil Flow\u003c\/li\u003e\n\u003cli\u003eDecreased Transmission Temperatures\u003c\/li\u003e\n\u003cli\u003eImproved Vehicle Response\u003c\/li\u003e\n\u003cli\u003eImproved Towing and Driving Ability\u003c\/li\u003e\n\u003cli\u003eIncreased Efficiency\u003c\/li\u003e\n\u003cli\u003eIncreased Reliability\u003c\/li\u003e\n\u003cli\u003eSupports Increased Torque Loads\u003c\/li\u003e\n\u003cli\u003eNo Slip Design\u003c\/li\u003e\n\u003cli\u003e300m Billet Steel Cover\u003c\/li\u003e\n\u003cli\u003eCustom Stator with High Flow Windows\u003c\/li\u003e\n\u003cli\u003eRedesigned Spring Dampener\u003c\/li\u003e\n\u003cli\u003eViskus Disc CNC Laser Cut Clutch Plates\u003c\/li\u003e\n\u003cli\u003eSquare Tab Construction (Not Round) Clutch Plates\u003c\/li\u003e\n\u003cli\u003e5 Clutch Plates\u003c\/li\u003e\n\u003cli\u003eRuns on Bearings that Wont Wear Out Like Stock Parts\u003c\/li\u003e\n\u003cli\u003ePlasma Welded for Unsurpassed Strength\u003c\/li\u003e\n\u003cli\u003eFully Welded Turbine and Impreller Vanes\u003c\/li\u003e\n\u003cli\u003eHardened Turbine Splines\u003c\/li\u003e\n\u003cli\u003eUnique Bonding Technology to Ensure 100% Chemical Bond (ATS Exclusive\u003c\/li\u003e\n\u003cli\u003eClutch Formulation)\u003c\/li\u003e\n\u003cli\u003eOptimized Factory Stall Speed\u003c\/li\u003e\n\u003cli\u003eATS Extra Deep Transmission Pan:\u003c\/li\u003e\n\u003cli\u003eEasy Installation\u003c\/li\u003e\n\u003cli\u003eHigh Quality Aluminum with Powder Coating\u003c\/li\u003e\n\u003cli\u003e5 Extra Quarts of Fluid Over Stock\u003c\/li\u003e\n\u003cli\u003e1\" Magnetic Drain Plug\u003c\/li\u003e\n\u003cli\u003ePre-Tapped for Sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBillet Input Shaft\u003c\/li\u003e\n\u003cli\u003eBillet Flex Plate\u003c\/li\u003e\n\u003cli\u003eFive Star Torque Converter\u003c\/li\u003e\n\u003cli\u003ebuilt 68RFE transmission\u003c\/li\u003e\n\u003cli\u003eReinforced Overdrive\u003c\/li\u003e\n\u003cli\u003eUnderdrive hubs and Compound Planetary Assembly\u003c\/li\u003e\n\u003cli\u003eDeep Transmission Pan\u003c\/li\u003e\n\u003cli\u003eReinforced forward hub and shaft\u003c\/li\u003e\n\u003cli\u003eReinforced intermediate shaft and hub\u003c\/li\u003e\n\u003cli\u003eModified pump\u003c\/li\u003e\n\u003cli\u003eModified valve body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eNext, 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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eModified 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.\u003c\/p\u003e\n\u003cp\u003eAt this point, we needed to look at the valve body and build it around the ATS Co-Pilot features. 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, we 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.\u003c\/p\u003e\n\u003cp\u003eClutch modifications are generally one of the most impactive and important items that can be upgraded in any transmission. In the case of the 68RFE transmission, there is little room for additional clutches so modifications must be done to pressure plates providing increased clutch surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe clutch surface area are:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e The Under Drive (Forward) clutch pack surface area is increased by 21%, using single sided clutch plates.\u003cbr\u003e 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.\u003cbr\u003e The 2C clutch pack surface area is increased by 34%, using double sided frictions.\u003cbr\u003e The 4C clutch pack surface area is increased by 34%, using double sided frictions.\u003c\/p\u003e\n\u003cp\u003eAll 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. The ATS Deep pan eliminates flex and works towards avoiding a cracked case.\u003c\/p\u003e\n\u003cp\u003eThe first thing that needs to be addressed is the clutch packs. These are the connection point for a transmission when transferring power in the gears. These clutch packs have a great deal of room for improvement. When we rebuild the transmissions in-house, we replace the overdrive, intermediate, and forward clutch pack backing plates with machined plates. This allows us to install an extra clutch in each pack. This gives us more surface area to hold added power or heavier loads. Being that there is less chance for slipping the clutches when engaged, it also increases reliability.\u003c\/p\u003e\n\u003cp\u003eNext, we move to the transmission pump. This serves two purposes: circulating fluid and pressurizing it. Our main goal with the pump is to increase its pressure output ability. By doing this, we can raise pressure throughout the entire transmission, which takes us to the valve body.\u003c\/p\u003e\n\u003cp\u003eThe valve body is known as the \"control center\" of the transmission. This is what mechanically controls gear up-shifts and down-shifts, converter lock up, Park\/neutral\/reverse\/drive, and line pressure. The main thing we are after here is line pressure, which the valve body acts as control. By increasing line pressure, we have the ability to increase the clamping force that is put on the clutch packs. Holding them tighter, also drastically increase the torque capacity on the transmission.\u003c\/p\u003e\n\u003cp\u003eFinally we direct our attention to the rest of the transmission. This includes replacing all bearings and seals with new parts, and replacing the bands as well. The case is cleaned and painted with a sealed enamel to keep your transmission looking good, and prevent any type of corrosion. And finally, our deep pan reinforces the case to prevent flexing or cracking.\u003c\/p\u003e\n\u003cp\u003eFor about twenty years, ATS Diesel Performance® has been a prominent manufacturer of diesel truck performance products known all over the world for innovation and solid workmanship.
