The Turbo 400, as
it is commonly known among racers and performance enthusiasts, made its
debut in 1964 as the standard equipment transmission in big block
powered GM vehicles.
Almost from the
moment it made an appearance on the street, the Turbo 400 attained near
legendary status as one of the strongest automatic transmissions ever
made. In addition to becoming the transmission of choice for serious
drag racers, pulling trucks and other mega-horsepower big block
enthusiasts, the Turbo 400 automatic found a home as standard equipment
in some of the most powerful and exotic vehicles ever produced. Today
the TH400 is only used as standard equipment in certain military
vehicles, but remains a favorite among horsepower enthusiasts in need of
a brutally strong 3-speed automatic.
Here at Rancho

performing transmission and make it better.
