A/T 4speed fails, car wont move until hot.
read all 100 posts and filter not mentioned changed out....im sure i missed it some how.....
so did you use snake oil next? (magic bottle of juice that makes transmissions work)?
say all actions taking in one post.?
and if the TV cable is good, end to end.

sure the fuel filter can be clogged, and 10x that if bad gas sold.

car wont move for 1minute to 10 is bad trans. (shifter works) and is line pressure failure doing those minutes.
cause is many. "only super man ,with xray eyes can find it"

could even be seals in valve body bad, even the MANUAL valve bad or leaking or just a weak pump. or a leak inside on the main pressure line.

$500 core
$1500 rebuilt
http://www.drivetrain.com/parts_catalog/...sions.html

the list of causes are huge.
even pressure reg .
if the pressure in to the manual valve is too low, the output of the valve in DRIVE (it is drive line) will be low.
or if the drive line feed, is leaking, same thing.
the TV cable and cause line pressure to be low.
as can pump, reg, and stuck manual valve , leaking OD clutch and others reasons
more....
forward clutch leaks.
"leakage from D range, fluid pressure circuit"
or any leaking Accumulators.. seals.... lots and lots of seals to leak in DRIVE.
the spec for P/n to drive is 1.2 seconds max.

the box is really built up a43DE box. more common, 2wd in base form. but is 4wd here,,,,, Aisin + Borg Warner box.

lets look at nicer drawing with this 41TE , simular but drawing is for drive mode... nice.
see the pump see those red lines. if those have leaks , it will fail.. in drive.
s1 to s4 solenoid valves.
the clutch servos are on top.

if the 7 minute delay to move is in reverse too?. then the problem is only on the bottom red lines, not the DRIVE red lines in center. see that?
that would mean leaks there, or regulator stuck or leaking
or a simple weak pump.

finding the true cause is very hard, most big shops do not try to, they send it out.
some builders sell rebuilt valve bodies, but what then, if that fails to fix it? at $300 a pop and not returnable. (warning they had 2 body styles and different parts inside)

its not that screen show above. its not dirty enough.
it's more serious.
im sure line pressure is too low.
and may be in reverse too, the FSM shows doing both, for good reasons.

but is the TV detent valve retracted? on the casing...
the TV stuck out , will not fix. start off.. delay
only make shifting way late.
but if it was stuck and the delay is tolerable, then you can skip a full fix. after getting TV working again..

line pressure is

D-idle=55-63psi., D-stall=166-188psi, R-idle= 73-81psi, and R-stall=202-237

real name is.
AiSIN Borg WARNER, A43DE.

all parts inside
