A/T 4speed fails, car wont move until hot.

You missed it:

Yes sir those RPM's are hot. Not even close to 800. But I does not shakes like a wet dog or want to shut off neither nor surges.

I would say 500 maybe 700? But yes off the gas and hot engine.

Well my bad about RPM numbers. I posted not close to 800 and that is not a number is a reference. but yes 700ish. Forgot to tell you also that my test drive was under Normal Shift Mode not using the Power Shift mode.

if the FPR looks old it is .....
Is indeed old
You mention that they don't last 20 years so my guess this one is 20yrs old


looks like its loosing power only on hills? and only driven fast.
You are just right. Are you sure you are not picking from TX? Relating to blind comment you made.

low fuel pressure
FPR bad.
(im assuming engine timed right /compression over 150)
injector screens clogged.
fuel filter clogged
bad gas
maf last, but must work 100% at WOT or the power will never be 95hP nor will the trans ever shift right with a weak maf.
really what is wrong here, lack of 95HP on DEMAND.
1 hp per cubic inch displacement here.

when i hear idle speeds wrong (still not reported yet, by you where RPM IS HOT)
my head goes. why.?
and wonders, is it too lean. or too rich? why.???? i never ignore problems, they like to stack-up.
they also can be the cause of the next hard failure. that early warning.
why ignore this , clear symptom.

Yes I have prolonged this too much.

if and engine is lean, running, it can burn valves. or ping (flogging a lean engine can do that)
i never ignore those early warnings
Would spark condition validate this?

are you sure this is 4speed
with OD lamp? (cluster lamp)
and OD switch? shift lever top.
and P/N tranny console switch??????
the 3speed, loves to smoke with the 3speed vacuum diaphram cracks.... 4sp has no such part.
Yes, pretty sure we have talked about this befiore(well written). OD lamp, n/p switch in dashboard, and button on AT lever etc.

some folks think TCC lockup is 4th gear, its not.
4th is a real gear and is aka. OD.

sorry for dumb questions, im blind here, and drivelines vary.
Is Ok. Sometimes thinking while writing I skip parts so I don't always write what Im thinking. My bad.

white smoke, with ISC pinched is the PCV valve sucking oil, as the plenum vacuum goes to moon. ( 25inches HG,just before a stall or near stall, 400rpm)
or the worst case test for intake valve seals, at that horrific vacuum , at that moment.
No the ISC was not pinched at that moment. It happened on stall test only.
