ATS has addressed the 47RH from bellhousing to tailshaft. The transmission's pump is modified to progressively raise line pressure, above the factory settings, to provide clamping force to the clutch packs. High-performance clutch packs are then added. Pressure plates are precisely machined to add 1 more forward and 1 more direct clutch. High performance bands, billet band strut, billet accumulator piston, and heavy duty overdrive bearings strengthen the clutch pack/band assembly.
Next is the valve body. Dodge 47RH transmissions can be plagued by sticking throttle valve issues. The valve controls shift timing and fluid flow to the clutch packs. When the valve sticks, there can be a no up-shift condition. In time, this can wear on the clutch packs and internals to hasten the transmission's life. ATS machines the bore to accept a Teflon sleeve, this ensures precise movement and control of the valve. 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. stock.
