3. Stronger Clutches and Bands

The TH350 was engineered to be robust, smooth-shifting, and efficient. It featured a planetary gearset, a torque converter, and a valve body that precisely controlled the hydraulic pressure to manage shifting. The design was based on the previous Turbo Hydra-Matic 400 (TH400) but was made more compact and lighter by using aluminum castings for the case and other components.

A Brief History of the TH350

While newer transmissions have emerged with more gears and advanced electronic controls, the TH350 remains a popular choice for enthusiasts who appreciate its simplicity, durability, and performance potential. It continues to be a reliable workhorse in classic cars, muscle cars, and even modern street rods. Performance torque converters are designed to increase torque multiplication, resulting in faster acceleration and improved overall performance. These converters feature tighter tolerances and higher stall speeds, allowing the engine to rev higher before engaging the transmission, resulting in more powerful launches.
