Went on a drive about 45 minutes away. Speeds were around 80-85. On the way back I noticed a small burning smell, didnt think too much off it as there were a bunch of cars around. 5 minutes later Im looking in my side mirror to a smoke screen covering the road. I pull over and there is fluid dripping from EVERYTHING. I let the truck cool down, sit for awhile, check the fluid, and theres enough to drive home thank god...
I get home, clean it up, and start the truck. Theres a big black round seal on the bottom of the bellhousing it seems to be, right behind the tranny pan, it seems to be leaking fluid. What is this seal, and why would is burst like that??

Two possibilities here. One is the torque converter seal if it leaks all the time and the other is tranny is overheating and venting fluid when it is hot.
My cousin had a similar problem on his (sorry to mention this here, I bleed blue oval personally) GMC 2500. He had picked his truck up from a body shop after having a fairly serious collision repaired. After about 20 minutes on the highway, the same thing happened, smell, smoke, etc. When he stopped and checked it out, tranny fluid was RUNNING out of the dip stick tube, onto the exhaust manifiold, and caught fire. Luckly, he was able to put it out without any real damage. The problem was eventually traced to a pinched transmission vent tube. When the truck was wrecked, the tube got pinched. It was in a non-cosmetic area and he had the body shop do a quicky fix up because it was just a work truck so it was never spotted. Maybe your vent is plugged? I don't have much experience with automatics (all my stuff is stick) and this was a GMC, but if there is a vent tube, it may be worth a look.

Ill have to find where the vent tube is on the tranny and check it out. Thanks.
