No automatic I ever knew had a shift detent going from Drive to Neutral.
But there is a detent going from Reverse to Park.

Hmmm - so you mean you can be driving along the highway and just bump
it into neutral? Funny thing - I guess it is old age - I have had this
car for years and really do not remember if it was originally like
this.... duh... I was assuming something had given out on it.

Thanks for the clarification. Ole Betsy requires a lot of work. Had it
since new and it has not been babied, so there is a looong list of
things to be done. Sounds like I can at least scratch this one off my
list. Thanks again for the input.

Yes, I think all automatics you can bump from drive into neutral. I think
it is a safety feature so that you can always kick it out of gear if need
be. You can't bump reverse into park, though. That causes damage to the
transmission. Joe M was good until he got to the R to Park. lol That
causes lots of grinding and noise and if you do it at a fast enough speed
and enough force on the lever, you discover you no longer have park. Don't
try it at home, it is an expensive lesson. lol

Some very old Powerglides went PNDLR instead of what we consider normal with
PRNDL or PRNDLL today. I don't think there was a detent between R and L or
maybe not enough to prevent accidental changes. I believe the old '50s GM
Hydramatic transmission was also set as PNDLLR and maybe some Ford
automatics. The '50s had a lot of pushbutton automatics for Chrysler, so
I don't know if Chrysler had any sticks with PNDLR or not.

Yeah verily, a lock to get into N could cause
'concern' in some tight full throttle
situations. (remembering back to those IAC
incidents in Audis... did those cars have a
lock-out on neutral?)

The Powerglide's PNDLR was a money saving 'mod'
to the standard (at the time) Hydramatic NDLR.
It saved some valve logic in the transmission.
The Hydramatic parking pawl was engaged by
pulling the selector into 'R' after the engine
was stopped.

Early Hydramatics had no locking detents. The
selector could be moved to any position,
anytime. The parking pawl would not engage
unless the pressure on both the front and rear
pumps was zero. 'Low' wouldn't engage above 40 mph.

The old auto's with a rear pump could also be pushed started at a high
enough speed...
