The torque converter housing pinion bearing cup in the AF50-8 transmission must be removed during unit repair procedures. GM-51919 is a unit repair tool that consists of a support bridge and two legs with specially shaped feet. The bridge features multiple attachment holes for the legs, allowing them to adjust to fit the ID of the bearing cup being removed. This feature makes the tool universal for future applications, as bearing cups that previously required essential inline tools will no longer fit. The other three bearing cups in the AF50-8 transmission can be removed with inline tools that dealers already have.
