7.3 eXcursion, tranny gone what to do?
time line of events.
Last Friday i decide work has had to much of my time and the weather was supposed to suck later so I bailed and a buddy and I went for a dirt ride, good one too.
on the way home I picked up a small vibration a 65+ mph, in my Excursion and figured maybe it was the road or possibly even a wheel weight.
pulled over to check it out and found nothing that could cause it, still thinking wheel weight.
Pulled back on and as long as I was under 60 it was mild, then it started getting a little worse. Then bad.
Decide I need to pull over but the section of road I was on was not good for that.
Rest stop is 1/2-3/4 miles away and I figure that is my goal.
By the time I got to the off ramp it was bad, really bad and I was going as slow as I could, but fast enough to keep from getting ran over.
it is really bad now and I start thinking motor or tranny as it is at any speed.
pull in and stop, shift to N and rev....motor sounds good.
shift to reverse and rev......just rpm and no movement,then to drive and the same thing. Get out to about 8 quarts of atf running down the lot.
on site diagnosis revealed driveshaft bolts had mysteriously come lose causing the shaft to get out of balance and shake.
this is what I see


then I move to the trannyand see the 5 rear most pan bolts have vibrated out and are sitting on I-25 somewhere, this of course allowed my fluid to drain.
wrecker gets it home, I get new bolts ordered, they came in today and I start putting some things together to evaluate.
drop the pan and drain the remaining oil, only to find one of the little bolts from my valvebodies (?) stuck to the magnet.
grab the torque wrench and the bolt to tighten all the others and install the missing one.
Cant find the bolt hole, but where did it come from??
oh there it goes right there.....
whats that, I see something strange looking.
anybody else see it??


in case you dont see it, it is a huge crack.
no scratch that, my whole transmission housing is cracked in half.
sweet <!--emo&:2thumbs:-->
so I am guessing that should run in the price of oh say $2500+
not just a rebuild of internals I need the whole kit n kaboodle.
what am I looking at:
for cost?
does my theory sound reasonable as to what happened?
in the rebuild stage what should I do to make this tranny better?
I tow regularlly about 8000 pounds.
anybody know a good tranny shop in Denver/Parker Co?
I figure a recomendation is better than the yellow book.
Also I have a BTS valve body matched to my DP tuner what needs to be done with that VB?
Guess I should call Brian and Jody.
thanks for your help guys looks like my dirt racing season budget just got eaten up, 1st race is paid for and in 2 weeks so I would like to make that but???
ya know what they say:

sorry for the ignorance..
I called Brian at BTS and good golly I wish I had some more money, he is about half again as much but it would be forever fixed and no worries towing with that.
