First offered in full sized Ford cars and trucks in 1979, this transmission quickly found its way into the ever popular 5.0 Mustang in 1984.

Performance Automatic recognized the future potential of this transmission and quickly went about re-designing the hydraulic circuits. What emerged was a transmission that could handle
more horsepower and torque than was originally thought.
