[FWDLK] 59 Torqueflite problem: News ...

["Philippe COURANT" <accf_clb@xxxxxxxxxxxxxxxx>]

Some days ago I write an e-mail about a Torqueflite problem: after a 1/2 hour of
 drivin',
the all new rebuilt transmission "died" suddently : no drive anyway ! Several
 tests after
(oil level, cable, regulator valve) and after drain the converter, results were
 strange:
no drive and the converter remains empty, even in N ! As I said, it seems that
 ther's a
front pump problem.
Today I've found the solution (i think..). I took the pressure line : correct !!
 Around 70
psi but identical in all positions ... So the pump was driven. But, why the
 converter
remains empty ?
Before removing the trans. from car, I would make other checks so I remove the
 oil pan.
Bingo ! There was a 1/2 inch of mud-paste-mixture in the bottom and the oil
 strainer was
completly clogged with this "like grease" mixture. So the pump couldn't suck any
 oil ..and
the converter remain empty.
But, from where this mixture come from ? Not from the trans. as I rebuilt all
 the
components and flushed the case. It could only come from the converter (not
 flushed)  but
why, when i drained the converter, the oil came through very clean ?
I think that, before rebuilding the trans., some oil passages were a little
 clogged so the
"mixture" remain in the converter and couldn't reach the pan (oil was clear at
 removing);
but, after cleaning the case, all the mixture was free of motion ... So it fall
 in the
pan. And now I must remove the trans. and clean all the components: if ther's
 dirt in the
pan , ther's also dirt in the valve body, oil passages, clutches, pumps etc...
I don't know if ther's still some "mud" in the converter; I'll try to flush it
 (as
described in the FSM) but itsn't easy: oil access holes are very small...Does
 someone has
flushed a converter ?
