i'm in compleat agreement.  i'd rather the front than the rear, too.  though
to be honest, i'd rather that none of it leak, really.  at least with the
Scout the whole front is easily accessible.  there's just nothing in there
to get in the way.  pull the radiator, drop the oilpan, and i might be able
to do the job right there.  we'll see.

now that you mention it, i do remember you having that problem.  i'll check
the valve immediately.  in the meantime, in all honesty i wasn't sure if the
front reservoir went to the front or the back...  in doing a brake check, i
discovered that the brakes i didn't have were up front and the brakes i
*did* have were in the back.  rear reservoir full, front reservoir empty.
refill, bleed, refill, bleed...  front brakes operational again.  week
later, empty front reservoir, no front brakes.  i put two and two together
real quick after that.  <Grin>

fortunately i hadn't been driving the thing for a while, otherwise it might
have been a serious problem.  i was driving the Scout, though, and handn't
even looked at the TravelAll for a week at least.  now i go out there and
look it over at least once every couple days, see if i need to do anything.
the batteries, both of them, have started going flat if it sits for more
than two or three days without being started.  i think it's the isolator, so
i'll get that replaced soon as i can.

you know, i can't tell if it leaks more when parked than it does when
driving.  it doesn't seem to leak at all if the engine isn't running,
though.  does that mean anything?  i'll look close at the shift shaft seal,
as that seems the most common leak point with these things.  i get a lot of
fluid runnin down the bottom of the bell cover from the front near the flex
plate, though.

something else i've noticed, and i'm not sure what it means.  i can always
tell when the transmission is getting low on fluid...  it starts operating
correctly (or at least more closely to the way the one in the 1010 did).
when properly filled with fluid, the shifts from second to third are mushy
and soft, and the shift points for both are too low.  but as the fluid gets
low, the shifts from second to third get more and more firm, and it shifts
properly at the right rpms.  also, as it gets particularly low, the stall
converter actually grabs more positively and i can almost spin the tires on
asphalt (and it *REALLY* spins 'em in sand).  what's going on here?

incidently, the shifts from first to second are always firm and solid, the
way i prefer them to be.  as the fluid level changes, the shifts do not.
only the shift points change.  from second to third, even if i manually
shift at a higher rpm, they're still a little mushy, regardless of fluid
level.
