THE TURBO 350: A LEGACY OF RELIABILITY
The Turbo 350 (TH350) transmission, introduced by General Motors in 1969, revolutionized the automotive industry as a lightweight, compact successor to the Powerglide. Originally engineered as a collaborative effort between Chevrolet and Buick divisions, this three-speed automatic transmission quickly became the standard bearer for GM vehicles, serving everything from daily drivers to high-performance applications. The TH350's innovative design, weighing approximately 120 pounds, featured a cast aluminum case, three forward gears, and a simple yet robust planetary gear system that proved capable of handling up to 350 horsepower in stock form.
Modern advancements have transformed this classic transmission into a versatile platform for both restoration and performance builds. Today's aftermarket support includes heavy-duty input shafts, updated clutch materials, reinforced bands, and performance valve bodies that can reliably manage over 500 horsepower. Key improvements include carbon fiber clutches, hardened gear sets, and electronic control modifications that bring this legendary transmission into the 21st century. Despite newer transmissions with additional forward gears, the TH350 remains a popular choice for hot rods, race cars, and classic restorations due to its exceptional balance of strength, simplicity, and adaptability.
