ATO SHD 47RE/48RE Diesel Automatic Transmission
ATO 47/48RE Transmissions are Redesigned to Withstand and Handle the demand of
todays Big Torque, Big Horsepower Diesels. Much of the Improvements came from
years of building 727 Torque Flite Transmissions for Competiton Drag Racing for
Improved Speed and ET with longer run time. Years of research and testing has
enabled ATO to design the Optimum Fluid Circuitry to Protect the Bands and Clutches
from Premature Failure along with Improved Converter Clutch Apply for more efficient
Clutch Lockup to prevent Clutch Failure under extreme conditions. ATO builds Longevity
into the Planetary by System Incorporating High Thrust Load Needle Bearings to Eliminate
the Heat and Friction that's common with standard thrust washers.
