i thought that 4th is controlled by the solenoid in the trans? our 46RH only has PRND21 like a 727 but has the 3 pron plug-in (not the N safety)...

gates are the same for the above as far as i know... PRND21

The overdrive unit is too large, there is no room for the bellcrank through the floor plus no mounting bracket for the tab on the other end.
