We install a new billet input shaft for applications with extra big tires and modified power levels. The factory transmission on your Cummins will not be able to handle all the newly created torque from aftermarket upgrades. Next is the valve body. Most importantly, all transmission shafts are not covered by this Warranty on any transmission due to the capability of certain situations to cause stress-loads beyond the structural ability of the shaft. The valve body is more aggressive than our Comp1 unit, but still provides a street friendly driving experience. Stock transmissions are only designed to handle the torque of the stock engine.
Pressure plates are precisely machined to add 1 more forward and 1 more direct clutch. The transmission's pump is modified to progressively raise line pressure, above the factory settings, to provide clamping force to the clutch packs. We re-program the valve body for higher line pressure, and add heavy-duty clutches with up to 25% more material than stock. We remove the thrust washers and install roller bearings throughout the transmission which eliminates oil contamination, maintains tolerances, reduces heat and prevents premature solenoid failure. Please plan for this when ordering.
The increased capacity comes from the material itself, which is stronger than the factory input shaft. Along with the factory plastic accumulator piston is replaced with a billet unit as well. There's another issue with autos dying just after a transmission fluid change. The increased capacity comes from the material itself, which is stronger than the factory input shaft. In addition, the valve body is modified to circulate fluid in park, reverse and neutral, capable of locking the torque converter in any forward gear, and raising line pressure vs. I've blown exactly one transmission in my driving lifetime, it was a Dodge 727 Torqueflite in a Ramcharger and that one had 200K + miles and everything was worn out but the shell basically.
Part of the appeal came from the availability of two unique powerplants: the immensely popular Cummins turbodiesel and the world's first V-10 to be offered in a light-duty truck. This Warranty shall not apply to any automatic transmission that has been improperly stored or installed This Warranty shall not apply to misapplication, improper operating conditions, accidents, or neglect. The valve controls shift timing and fluid flow to the clutch packs. Also, there was erratic operation of overdrive kicking in without provocation. A heavy duty truck needs parts which can stand up to heavy trailers, stop-and-go commutes to work, or high-horsepower applications. Next is the valve body. Truck Freight Item: Allow 1-2 Weeks for delivery.
The 2nd time in the shop, they replaced the transmission, clutch and slave cylinder, this worked. Drop these into a used-up, preproduction number 00081 Dodge Ram 2500 pickup headed for the crusher. Featuring a finned design to dissipate heat, and adding five quarts of fluid vs. Not only do they fail on trucks with minor upgrades, but even trucks in stock form have been known to be too powerful. The first time they took the transmission apart and inspected and placed back into the truck. Truck Freight Item: Allow 1-2 Weeks for delivery.
Pressure plates are precisely machined to add 1 more forward and 1 more direct clutch. Get it fixed up someplace solid, add a Racor filter and make sure that the cooling is solid, run nothing but synthetics and you are then fine for 300,000 miles or more. This Warranty shall not apply to any automatic transmission that has been improperly stored or installed. Light throttle shift firmness is also maintained at these higher apply pressures and no shuttle shifting problems. Please plan for this when ordering.
This is the transmission that was used in both the 1st and 2nd place trucks in the Diesel Power Challenge 2014. If you let the interval go to long, you will have a lot of crud in there. It is mandatory for implementation of this warranty that line pressures are tested at time of install. When the valve sticks, there can be a no up-shift condition. The modification process began with the torque converter. At 64470 miles the trans went dry and dealer replaced another trans.
This Warranty shall not apply to any automatic transmission that has been improperly stored or installed. A little over kill but it has been worth it. This corrected the vibration noise which turned out to be coming from a broken snap ring that held the overdrive unit. In time, this can wear on the clutch packs and internals to hasten the transmission's life. Deep Pan and Torque Converter sold separately. See your dealer for details. We remove the thrust washers and install roller bearings throughout the transmission which eliminates oil contamination, maintains tolerances, reduces heat and prevents premature solenoid failure.
