It continues to be a reliable workhorse in classic cars, muscle cars, and even modern street rods. The planetary gearset is controlled by a series of clutches and bands, which are hydraulically actuated by the valve body. Each clutch or band engages or disengages to change the gear ratio within the planetary gearset, resulting in a shift from one gear to another.
The TH350 was the automatic transmission of choice for many of the legendary muscle cars of the 1960s and 1970s. Its ability to handle the immense power and torque of engines like the Chevrolet small block V8 and the Pontiac 400 made it a key component in these performance machines.
