white smoke well either your burning tranny fluid or coolant no vacuum modulator on an aod so i bet it's gonna be coolant pull your plugs to see if any of them are wet or if water comes out and check to see if there is water in your oil also look behind or under the car (whichever the case may be) to see if you have a coolant puddle at the end of the tailpipe i bet you have a blown head gasket(most likely) or possibly a tiny ultra microscopic crack in your #6 intake runner at which time you will pull your heads off and look at the head gaskets and say hmmm they look ok then you disassemble your heads and see nothing so you put it back together and it still does the same thing smoking like a freight train (this happened to me) seriously though i bet it's a head gasket.
