In the early 1960s, GM engineers embarked on a mission to develop a three-speed automatic transmission that could handle the increased horsepower and torque outputs of their new generation of engines. This mission led to the birth of the Turbo Hydra-Matic 350, which debuted in 1969. For more details https://carsinspections.com/transmission/what-cars-came-with-th350-transmission/ The torque converter consists of two main parts: an impeller connected to the engine crankshaft and a turbine connected to the transmission input shaft. These parts are separated by a stator, which is free to rotate but is connected to the transmission case. A shift kit is a collection of valve body modifications that change the transmission's shift points, firmness, and overall shift characteristics. It allows for firmer and quicker shifts, enhancing the vehicle's responsiveness and performance. The TH350's adaptability extended to other GM vehicles, including: Installing a larger transmission cooler and upgrading the fluid filter helps ensure optimal operating temperatures and clean transmission fluid, extending the transmission's lifespan. When the engine is running, the impeller spins, creating a hydraulic force that rotates the turbine. The stator acts as a reaction element, directing the fluid flow to create additional torque multiplication. In low-speed situations, the torque converter acts as a clutch, smoothly transferring power between the engine and transmission. As the engine speeds up, the torque converter locks up, eliminating slippage and improving fuel efficiency.
