[FWDLK] Tranny shifting

[Eastern Sierra Adjustment Svc <esierraadj@xxxxxxxxxxx>]

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 !
