Fits all year G-Bodies

  • NOTE1: OSR = Outside Snap Ring; ISR = Inside Snap Ring.

There are basically only two types of transmission slip yokes for all G-Body applications. Now OPGI has both of them, brand-new with different lengths, depending on the application. They're made from ductile cast-iron and are machined to the exact same tolerances as the GM originals. Between the two different spline counts and the different lengths, one will fit all GM manual or automatic transmission applications.

The 27-spline fits Powerglide, TH350, 700-R4, 200-4R, early B/W T10, all Saginaw manual transmissions. The 32-spline yoke fits the TH400.
