Staghound Hydramatic Transmission Question

[Malcolm Towrie]

Your setup is the same as the Staghound, see photo. Nearest the engine is the cover for the front band adjusting indicator pin, as Marco says. The cover's missing in the photo. Then the front band adjuster, the pressure switch, the rear band adjuster, and the rear band adjusting pin.

GM had designed the Hydramatic just a few years before and, boy, did they modify it on the fly. First no band adjusting pins, which I think you said is like your other tranny. This requires removal of the tranny to adjust the bands, which was a routine task!
Then two pins to allow external adjustment of both bands.
Then they made the rear band self-adjusting, so only the front band had the pin. The Chaffee has this setup.

I don't know how far you are getting into the trannies on the M5, but the adjustment of the linkage between the carb and the tranny is critical. The tranny needs to know engine load so it can delay shifts, increase pump pressure, clamp bands and clutches tighter under load, etc.
