The input shafts are different lengths also. Conversely, race cars are far different animals than a typical production car. The heart of the first-generation Powerglide was its torque converter (above). Its gear ratios are: 1st gear: 2.74 2nd gear: 1.57 3rd gear: 1 4th gear: .67 For the 1968 model year, Chevrolet introduced a semi-automatic version of Powerglide marketed under the name Torque-Drive.
