Transmission:    4R70W - 950

We consider the 4R the greatest 4-speed overdrive transmission available (for its size) in history.  The Armageddon 4R is built to prove it.  This transmission is designed around the fact that lockup is not feasible beyond 700 to 800 ft/lbs of torque.  The TCC and converter have too much inertia in this power range and wreak havoc on input shafts and drums.  At this time, I only offer this transmission built with a typical input shaft design, however we are working on a solid, one-piece design comparable to what is utilized in our AOD-950.

You can call it a glorified AOD if you wish, but it fits Ford modular motors.  Like the AOD-950, this transmission utilizes special machining and hardening processes on the drums and other internal components to increase reliability in high horsepower and torque applications.  We take out all of the stops for this transmission.   It is fully rebuilt using F7 or newer cores we have available.  Each unit is fully inspected for wear, all gaskets and seals are replaced with quality new pieces, and final clearances are adjusted for performance use.
