I have a 95 sonoma 4.3L and when i start it it those loud noise until i put it into (D) drive. when i put it back into park it those a loud noise then itt keeps doin a sound
hard to explait but im only 17 and dont know whats happenin

and my clock stays on when my ignition is off

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?
