Is it a clanging-banging noise under your feet until you shut the motor off?

Its more of a loud humming noise, when i shift it from drive to park it does a loud cluking noise then starts humming

I've seen a torque converter nearly disconnected from the flexplate bang in park then get quiet in drive but I haven't had what you mention.
Maybe someone else is familiar.

wen i start the truck sometimes it starts really fast, i dont even have to turn the key the whole way. it does the noise only in park or neutral not in drive u think its in the stearing colomb?
