On the road...

Ryan, the tranny cooler may not be at the radiator. I forgot what
year bus you have and it is not in your post. On my 94pt there is a
big pipe under the radiator that has tranny lines in and out. The
pipe also has two large radiator line in and out. this is the part
MikeH refered to that failed and allowed water to mix with fluid.
If you are losing fluid that is better than taking on water
(coolant). The trans cooler pipe is a borgWarner part. If you are
dumping fluid into the radiator you should see white residue around
an opening like the puke tank. If it was my bus I would call the PO
( previous owner) and contact the rebuilder for input. I would also
ask the PO more questions on what was going on when he was required
to rebuild the tranny. If he repeats the symptoms you quote here,
maybe the failed tranny was a result and not the cause of failure.

My bus would show a do not shift light from time to time and I was
unable to have the computer read because the Allison dealer said it
goes blank when you shift into reverse????? The intermitting idiot
light went away and never cause a problem with shifting.
