Trans problems

[pat]

I recently put in a new, or supposed to have been rebuilt, tranny in my Jimmy.
It was working fine for about a week. On my way to an interview, driving into about 30 mph wind, I suddenly see a cloud of smoke behind me and nothing else. All my tranny fluid dumped out in 10 seconds. I havent looked at it too close yet, but Im thinking it may be coming out of the base of the dipstick. I remember when I put the tranny in I was having problems getting it to go down all the way. So I just put some silicone on the base and it didnt leak. Is it possible that the dipstick got pushed out some somehow and the fluid all leaked from there? Or did something else really bad happen?
