Product images may differ from actual product appearance.

TCI GM Speedometer Gears fit most popular transmissions like the Powerglide, TH350, TH400, 2004R, 700R4, etc. Choose from many gear options.

The formula below will work for any GM, Ford, or Chrysler vehicle; it is very useful when there is no established baseline from which to work, such as replacing a transmission in a vehicle that was purchased without a driveline.
