actually forget that thing it weighs more than the engine, parts are next to impossible to find, needs periodic adjustment, and has no park.

Had to be an a$$
sorry

Ahh but it did have a “park” in consumer vehicles .

Although it didn’t have a park position on the selector .

Remember when this “new fangeled” automatic transmission came out it was customary to put your manual trans in reverse when parked , why because reverse was generally the lowest gear .

So it was a natural thing to put the automatic in reverse when parked .

The 4 speed Hydramatic has a parking pawl that is held off when the engine is running and the transmission is pressurized . When selecting reverse and shutting the engine off the pawl in no longer held off and a spring pushes the pawl into engagement with the components directly connected to the output shaft of the transmission .

Start the engine in neutral and drive away in whatever gear selected .
