Recall Notes:
Chevrolet campaign no 74-c-19. Possibility when the allison mt-650transmission is matched with either the 366 or 427 cid v-8 engines, the 1,3 to1,0 governor drive-to-driven gear ration can create excessive governor rpm whenoperated in top gear at or near maximum rated engine speed rpm of 4000. Theexcessive governor speed can result in a governor driven gear failure. Afailure of this type can cause a down shift of the transmission withoutwarning. If this occurs, transmission and engine speed would increase greatlyand may result in one of these components breaking. (correct by inspecting andinstalling new transmission rear housing assembly and governor with 1. 0 to 1. 0 drive-to-driven ratio. )
