Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • No model-year or vehicle fitment can be certified from the supplied casting numbers alone
  • Identification requires assembled transmission code, gear tooth counts and spline verification

Product Overview

This listing describes a Muncie-style four-speed transmission with an M22 ratio claim, but the stated casting references identify different parts and production periods. In particular, 3851325 is an early main case, 3831707 is an early side cover and 3857584 is a later tail housing. None of those castings alone proves M22 gear ratios. Request verified photos, tooth counts, input/output spline details and assembly code before treating the transmission as an M22.

Before ordering, compare this exact assembly with the part currently installed. A similar name or model year does not guarantee the same mounting, connector, dimensions or equipment options.
