7. Showing the piece-by-piece reassembly of the StreetFighter takes more space than we have, but simplified, the rear drum friction band goes in first, mating up to the rear band articulating arm. The reverse clutch drum and ring gear and planetary slide in next. It’s followed by the rear planetary gearset, the sun shell and sun gear, the front planetary, and the front and rear clutches. The 727 uses a for-the-time revolutionary Simpson gearset designed by Howard Simpson that uses one sun shell for two planetary gears.
