I have a 1999 f-250 4X4 with a 7.3 engine and have quite a transmission
problem. As long as the truck is in neutral or drive there is no
problem but as soon as I shift into reverse the transmission begins to
absolutely gush fluid. It looks as though the fluid comes from
somewhere up on top out of direct sight. The transmission still shifts
into reverse and drive smoothly (that is as long as there is still
enough fluid). Does anyone have any idea what the problem could be? Any
info would be greatly appreciated!

Yep, only in reverse. That what stumped me? I can drive miles, but once
I shift into reverse fluid comes pouring out.

This problem seems to be the case. I have 3 F350's in my
files over the past 2 years that have caught fire when this
happened. All three were found with the dipstick pushed out
a couple of inches and the right side of the engine
compartment doused in trans fluid. It also appears to come
from the case vent which would indicate the case vent to be
clear. There is no indication of seal leakage. It does not
appear to be related to heat as one of the units had been
parked for 6 hours just before it started to back up with an
equipment trailer. It had moved less than 50 feet when it
burped and caught fire. One of the 3 had this happen in two
prior occasions without catching fire. Trans was pulled and
built after each event. If anyone comes up with a cause for
this, I would sure like to hear about it.

Wow, that's scary. Thanks for the heads-up. If I find the cause
I'll let you know.

Off the top of my head I can think of two things that could cause
this. One is a bad leak in the reverse clutch pack that it routing a
lot of oil back to pan in a path the is trapping some air and bubbling
fluid out, the other is a bad leak in the valve body reverse circuit
that is doing the same. Some how a lot of fliud is being expelled
internally were it is not supossed to be and it is trapping air in the
process through leakge and or areation caused by the leakage and
causing the effect you have. Also with a big internal leak the pump
could be cavitating and sucking air and creativing a oily foam that
would vent out too.
