Larry,
Those would probably be good candidates for the "...blunder" section of the
Rock Auto monthly newsletter!! I, however, probably have more such
candidates than you!!

Ever just shoot yourself in the foot...not once but twice?
I've been struggling with a transmission that has been running about 40-50*
warmer than what has been normal. On an 80* day the trans temp would run
about 180-190*. Normally under the same circumstances trans temp was closer
to 130-140* This is my first run following a fluid and filter change.
With the discussion on this forum, I've been assuming that the problem was
probably the trans filter with a slightly undersize feed tube allowing air
to infiltrate the system. Two days ago when I found excess fluid in the
overflow bottle, I decided to check the fluid level. WOW...it appeared to
be
about 2-3 quarts high with some air bubbles also on the stick. So, somehow
when I changed the fluid, I put to much fluid in the trans. Don't know how
I could have done that, cuz I ran and checked the fluid multiple times
during the refill, then took it for a ride and checked it....but I did....
POW...the first shot...I seems somehow the fluid level reached the rotating
assembly and the contact introduced air bubbles into the fluid, raising
the volume even more. So now I am charged with the task of removing some of
the fluid (I figure about 1 ? qt) without making a mess on the parking
pad in Natchez State Park. I found a catch container (cheap Styrofoam
cooler lined with several black plastic bags), raised the coach enough to
get
the catch under the trans, pulled the vacuum modulator out and drained about
2 qts. Son of a gun...No runs, NO drips, no mess!! Put the modulator
back in and checked the fluid level. Now about a pint down (cold). So I
figure, tomorrow I'll run it for a while on our way to the next stop and
check it hot. Next morning I pull into the dump station, dump and pull out
onto the entrance road and hook up the car. Start the coach and
...POW...the second shot...no drive. Shut it off, step outside to find about
a gallon of fluid on the road. Apparently, when I put the modulator back
in, the forked plate that holds it in, did not catch the flair on the
modulator. Pressure of putting it in drive the 3rd time popped the modulator
out, and there it was hanging from the vacuum line.
So, now I can't move the coach and there is a gallon of fluid where I have
to lay to get the modulator back in the trans. We soaked up as much fluid
as we could before I got to the modulator to reinstall it, Anyone out
there experience rolling around under the coach in trans fluid? Even with
cardboard as a barrier between me and the fluid on the road, I ended up with
my right side and back soaked with trans fluid.
Oh...BTW...Yesterday we made it to the next stop and the trans is back to
normal temps with fluid level at about 1/2 pint low. Life is .....better....
