My mechanic friend / shop manager says Seafoam is great, both the trans and
the engine oil additive for sticky lifters.
IIRC the sixties aluminum TorqueFlites have a relief valve which engages in
the park position to drain excess pressure off the torque converter to
extend the seal life.

Subject: [FWDLK] Tranny shifting
I think that Dan has diagnosed the problem, but, the cure may be in some
question.
I called my friendly tranny-shop today (which doesn't "like" to work on
cast iron 'Flites, as they are somehow stone-age
compared to the alloy-boys).
Anyway: he said to take a dipstick reading now, with the car stone-cold,
and then either drive it or run it thru the gears (I already
well-knew about the fullness-reading protocol) , and then wait about 1-3
minutes, and re-check the 'stick, to see if the fluid
may have returned to its cold-level (due to anti-backflow leakage, in the
torque converter. The T/C drains-down, and then needs
to be 'pumped-up' with fluid before the tranny will initially shift
gears).
I recorded a cold-level' well beyond the word "Check" , on the stick.
After starting the car, but before I tried to engage any gears, I waited
20-ish seconds to see if that time period
might allow the T/converter to pump-up.
The car went right into gear, after allowing the T/C to pump up.
Instead of taking a test drive, I started the car and went thru the gears,
for about a minute, and re-checked the stick while
the engine was running, in "N" (naturally).
The Fill-level was, surprisingly, about 1/8"-1/4" below the "F" mark.
Turned off the engine, waited 3 minutes, and re-stuck the trannie and
recorded a fill-level @ the first C in "Check", which
was more of a net-difference between cold-and-hot, than was the amount of
under-full that I recorded.
Presumably, a non-leaking-down T/C would either hold its fluid level, or,
take a lot longer to drain-down.
So, I will test-drive the car, again, to see if the fill-level might
actually be low, but, that doesn't appear to be the culprit
as far as the leaking-down T/C is concerned.
If the trannie is in fact low, then I don't need to worry about buying a
filler-tube drain pump (no small pump-system seems
to be available in our Burg, anyway).
No one seems to carry Sea Foam, but Kragens says that it stocks Lucas,
Prestone, and Barr's additives.
I'm going to be going to Carson City next month, so I should be able to
get MoPar trannie fluid and the Seafoam stuff (at a Wally-
Mart?)
I like the idea of a sort of long-term additive, like Seafoam; anybody
had any experience with the three above-referenced products?
BTW, I really like Lucas' power steering Stop Leak, but Lucas' engine-oil
additive has been shown (on an internet-site; yeah, I
know: the internet is 'always' right!) in a see-through enclosure, to
RESTRICT oil from adhering to a set of gears, at speed.
SO, it looks like I might need to seal-up/rejuvenate the T/C's
anti-leakdown seal !

Change your filter/fluid. If no change, your anti-backflow seal in the
