mehr zu GM Turbo Hydramatic 400:
The Turbo Hydramatic 400, or Turbo 400, as it is more commonly known among racers and performance enthusiasts, made its debut in 1964 as the standard equipment transmission in big block-powered Cadillacs and other full size GM vehicles.
Almost from the moment it put in 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 – from V12 Jaguars and Ferraris to Full Size Jeeps and military vehicles. Today, the THM 400 transmission is only installed as original equipment in certain military vehicles, but it remains a favorite among horsepower junkies everywhere in need of a brutally strong 3-speed automatic. Although Turbo 400s are already stout in stock form, a TCI® prepped Super StreetFighter™ or Competition Turbo 400 can handle over 600 normally aspirated horsepower.
