E4OD leaking fluid.
I was driving around town for about two hours, city and highway in my '95 5.0L Bronco yesterday and noticed blueish smoke in my rearview mirror. I pull over fearing the worst, thinking I may have blew a headgasket or the valve seals were going. Turns out I'm leaking tranny fluid all over the place, (blueish smoke from under the hood, a small puddle under the truck and a drip trail of ATF). Any idea what the problem could be before I take it to a tranny shop?
Thanks,

If the fluid is coming out of the bell housing area you might have got the trany hot and the front seal flipped and puked out fluid. On some occations I've seen the seal stop leaking after the trans had cooled down. A buddy had this happen 6 months ago, refilled the trans and it hasn't leaked anymore.
You could change the fluid and filter and clean out the cooler(s) as a little preventative measure. Hopefully you'l get lucky and it won't return for a while...

Where is it dripping from? A cooling fitting, the bell housing, the tail shaft, where?
Smoke comes usually from either the fluid dripping on a hot exhaust pipe, which isn't to bad and usually cheap to fix. The other usual source of smoke is the tranny itself which is bad. This means the oil is "burning inside the tranny itself. Probably means a rebuild.
Check you fluid level, I would bet it may be pretty low and or foamy. Also check for color and smell. It should be red or at worst pink. It should also smell nice and chemically. If it is brown or black and or smells burned, then you found your source of smoke.
Good Luck, let's hope it is just oil on a hot pipe.

It's pouring here so I didn't get a chance to get under the truck today. I'll climb under it tomorrow. I bought some Lucas transmission fix and hopefully it'll solve the problem.
If it starts leaking again, I'll take it to a professional.
