We are pleased to announce the immediately availability of our new Circle Track series of Powerglide transmissions! 

These transmissions feature low gear only, and must be used with a functional torque converter.  Direct drives cannot be used with these transmissions.  These transmissions are a great choice for Factory Stock dirt track applications as well as any other class that can benefit from a lightweight, low-gear-only Powerglide transmission.

The following part numbers are currently available: 

  • 28-2-76CTLG – Circle Track Powerglide transmission assembly, standard length, 17 spline input, 27 spline output, low gear only, standard OEM depth steel pan, 1.76 ratio
  • 28-2-82CTLG – Circle Track Powerglide transmission assembly, standard length, 17 spline input, 27 spline output, low gear only, standard OEM depth steel pan, 1.82 ratio

We recommend the use of torque converter part number P8TOW for racing classes that require an OEM-style 12-inch diameter torque converter.
We recommend the use of torque converter part number 10” PG IMCA B for racing classes that allow the use of a smaller diameter torque converter.
