Converter drainback is a perfectly normal occurance, there are service bulletins advising owners to start in Neutral instead of Park.

why is every one ragging on this guy for wanting his car to act right? Mine does it too, and it kinda pss's me off too.
Because Ford and Chevy figured this out and didn't have this problem. But Mopar is PERFECT in everything they do. So if Mopar is perfect then it really can't be a problem.....
My old truck takes quite a while to warm up, even though I live in Atlanta. I often go and do things while it warms up even if it is something as simple as taking out the trash or the recycling. And my driveway is slopped. So it is a PITA to sit there for a few minutes in neutral (and yes, depending on where I am in my driveway it is too steep for the parking brake to hold and is a grade beyond that specified by Mopar for the brake to hold). Maybe my life is just to hectic.  Or I shouldn't drive my old truck unless I have time to handle its peccadilloes.

So by extension, this has been a known problem for some 30+ years? Even new cars off the showroom floor may have had it? Or does some normal trans or converter wear eventually lead to this? I've got a stock 75 /6 with a 904, and a shift kitted 70 340 Swinger with the original 727 that do this...

My sentiments exactly. Quit ragging on the guy for wanting some help with the proverbial 727TF tranny drain back. Mine does it and after it warms up it is fine. He is right to be concerned about parking on what he has described as a steep grade in his drive way. And by the way...even the new 518 trans have the same issues as their older 727 cousins. It is what makes these old MOPARS unique beasts....

They eventually fixed it. And by eventually, I mean a '96 I had and then sold to my dad does this and there is a warning in the owner's manual about it. So it was after '96. If yours goes into drive right away and doesn't act like there's anything wrong I think there is little to worry about. We've had an '83 pickup since '86 that we could always just drop in gear and take off without problem. It has at least 180,000 miles on the same transmission. ... the valves seals on the other hand.... And don't worry. I can take some ragging. Especially when I know I'm right!

CRT manual valve body in mine I ask john about the pumping in park or N said it pump in N not park but did have a new valve for converter drain back but thats not a homebrew VB either  non of my 727 have ever done this that I can remeber...or any 904s I have run maybe I got the good ones from the JY  but I do have a habit of starting them in N anyways for the warm up I would not rag on you...as low level performance/knowlege as I am...I want it to work correctly also.

What's wrong with the valve that allows the converter to fill in park? ... like Ford and Chevy do.
I don't know what was done to the 727 in my GTS, but it was fixed by a tranny guy in the early 90s. The point is that it can be done. But, for what it's worth, I've never had a Mopar auto that took a long time. Start it in Park, put the shifter in gear (reverse or drive) with the foot on the brake. Any delay in engagement has been mostly negligible.
