47RH Stage 3 Package, 1994-95 Dodge 2wd w/ Speedo Adapter. In re-designing the 47RH, ATS addressed inherent weaknesses to produce a strong, reliable transmission for towing, daily driving or racing.
The result is a transmission featuring:
- Five Star billet torque converter
- Performance transmission pump
- Modified high performance clutch packs/bands and steels
- Valve body built around reliability and increased transmission life
- ATS billet 300M input shaft and forward hub
- ATS Co-Pilot Lockup Controller
- Deep pan for added cooling and convenience
The modification process began with the torque converter. Instead of a stamped converter with a single lock-up clutch, the ATS Stage 3 47RH comes with our patented Five-Star torque converter. Utilizing a billet 12 bolt cover, five square tab lock-up clutches, a billet stator and other modifications, this converter is designed for heavy loads, years of reliability and brute power.
The goal is to efficiently transfer your 12Vs power through the converter into the transmission.
In order to handle the increased efficiency of the converter, we addressed the 47RH from bellhousing to tailshaft. The transmissions 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 transmissions 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.
On the Stage 3 build, ATS adds a billet 300m input shaft and forward hub. Featuring a two-piece design, the input shaft is designed to withstand greater than stock power, torque converter lock-up sooner than stock, increased towing weight and racing applications. The increased capacity comes from the material itself, which is stronger than the factory input shaft. This is coupled with a precisely engineered shaft, directed at absorbing torsional loads from increased power, and transferring it into the transmission.
The Stage 3 (as well as all ATS Transmission Packages) comes standard with the ATS Deep Pan. Featuring a finned design to dissipate heat, and adding five quarts of fluid vs. stock, the pan helps keep the transmission running cool. The ATS 47RH Stage 3 is designed for trucks with stock to moderate power increases, light and heavy towing and daily driving.
In addition, we include the ATS Commander Lock-Up Controller on this package. This controller allows the user to base lock-up on vehicle speed. Torque converter lock-up can be moved to 1st, 2nd, 3rd gear or overdrive and can be changed at any time. Our controller features in-cab adjustability, so settings can be changed with the push of a button. Every time the vehicle reaches the set speed, the converter locks. The benefit of early lock-up is reduced transmission temperatures, quicker acceleration and better fuel economy.
The ATS Commander Lock-Up Controller will also synchronize lock-up with an exhaust brake, for additional braking force.
For moderate to extreme power applications, heavy towing or competition use, call ATS to discuss which transmission package would fit your application. All ATS transmission packages come backed with a 5 year / 500,000 mile warranty.
