Jet-Away (Oldsmobile's name- can't remember Pontiac's name) were truly a 4-speed. However, the small extra fluid coupling (they were called Dual-Coupling Hydramatics) took the place of a previous clutch in the older Dual-Range transmissions. A shift into 2nd or into 4th gear involved filling the empty front coupling with fluid, so these shifts were "soft"- and no amount of internal modification could improve them much. They aren't "bad" transmissions, and some owners really like them. But like any old Hydramatic, they can be difficult (expensive) to repair or rebuild.
