Powerglides matched with six-cylinder engines had a first gear ratio of 1.82-to-1 and a direct gear of 1.00-to-1 for the second gear. In fact, the earliest Chevrolet technical literature often referred to the unit as a torque converter transmission rather than the more simple and familiar automatic. The original 1950 design employed a five-element, bolt-together converter that provided a torque multiplication factor of 2.20:1. In race cars, compared to a Powerglide a TH400 is better suited for cars with large tires and taller rearend gearing. The answer is identifying the gear ratio is quite simple. Someone feel free to jump in here if I am off base.
