I have taken the TE on several short trips of 40-50 miles, so today I drove
it 200+ miles and all is well. I am about to declare that changing the
filter fixed it, but I want to make a few more 4-500 mile trips to be
sure. Thanks to all who assisted with the diagnosis. Now if I could get

Here is the latest:
Sun Valley suggested installing a new Mann Trans filter, and fluid. To
them this seemed to be a common problem. They said the filter is probably
clogged or collapsed, as others on the list suggested. I ordered a couple
of Mann filters from Rusty, changed the filter
their mouth to clean the
dipstickand no spitting is not allowed.
Also allows us to taste the condition of the fluid.

They also check the accuracy of the temperature gauge by removing the

You call that macho? Hurts my back to bend over that far, I'd
suggest an appendage located closer to the engine. :-)

Vacuum doesn't control WHEN the shifts occur in 722.3/4 transmissions,
only how firm the shift is!

Are there springs in the valve body?
Absolutely. And BB's as check valves. I don't know about how
it's attached or sealed, but absolutely you can do it from below.
Cleanliness is all, however.

because you replaced the filter in may does not mean the filter does not
need to be replaced again. That is where you start. Anything beyond
that at this point is a waste of time.

do you know how the valve body is attached to the rest of the
transmission? I am wondering about pulling it out and seeing if the
gasket
or oring seal is the problem. Maybe I could find a used valve body.
Some number of small bolts or screws? I don't think it's very involved.
Just drippy.
Yeah, I am kind of looking at the Catheyesque method before I shell out
cash for a used trans. I am just wondering how the valve body seals to the
main trans body. Anyone know how the pump seals to the trans case? From
Herr Doktor's email, perhaps the pump to body seal may have given way.
Anyone know how the pump seals to the trans case?
The front pump seals to the case with a large O ring.
You can't even look at it without removing the transmission
from the car and taking out the torque converter and removing
the front housing.

yeah, I found the oring on Rusty's website. He was also kind enough to
send me an exploded diagram of the trans. It appears to be a 722.320 from
the info on Rusty's site. I suppose I will have to pay for a used trans or
a rebuilt, but the failure mode suggests a snapped spring or a blown out

The fluid and filter were changed a couple of thousand miles ago. I was
going to try that first, but figured it probably would not change much,
since it was recently done. My brother also suggested to see if the valve
body had loosened and was allowing fluid to bypass the normal circuits. He

is the valve body right there? I have never messed with auto trans

Sounds like a computer and/or vacuum malfunction. If it were mechanically
caused you'd be slipping or simply unable to engage in gear (e.g., FW or
RV). I knew when my transmission died because it simply refused to move in
ANY direction (1983 300TD).

I agree. Except that the computer in these vintages is fluidic,
not electronic, and ATF courses through its veins not electrons.
Your tranny is sick, in other words. You could try a fluid
and filter change as that's fairly cheap in comparison
