Smokin Bad

So I'm drivin thru the mountains in PA headin to OH when I notice that I'm smokin real bad. I was runnn up hill and let the motor load up in OD by accident. Then she startin to "pop" or missfire like it was loadin up with water. I down shifted to 3rd (shoulda dun that to begin with) and she ran fine till I could pull over. Whe I stopped I looked under the truck and could see her smokin from the back side of the engine/tranny area. Smelled real clean to, not like it was oil. Gave it a few minutes and it cleared right up. Now it smokes real bad whenever she's under a load in OD, kick her into 3rd and it's all good. Checked the tranny fluid, all clean and full, engine oil needs changed tomorrow anyway and I'll check the plugs as well. Any possible way I could be burning tranny fluid, or suckin it into the motor. I really don't think it was oil as it didn't smell like it. I'm gonna check my lines to the cooler as well. Oh yeah it's a 93 351w with the e4od. Any help is much appreciated as I have to drive back to VA Beach this week.

smell your tranny fluid. if its burnt or smell rotten then your tranny may have overheated causing the fluid to boil and push out a seal onto the exhaust. does the tranny act funny?
