another 'flutter" question

Hi all,
bear with me i'm new to the ford world. I have an 01 f350 4x4 v-10 auto with 4:30 gears and 40k on it. i just baught the truck last week and i noticed today around 2000-2300 rpm a weird noise thats sounds like an air compressor relief valve popping off when the take is overfull. it does it intermitently I watched monstas video but i couldnt tell for sure. does this sound like a flutter noise to you? or should i be worried about blowing a plug?

help!

thanks

I would be checking all your plugs!

Also check the inspection plate cover on the transmission bell housing. It's in the front of the tranny on the bottom, 2 bolts. You might need to put a foam gasket or something similar between the plate and transmission. Sometimes bending it slightly will alleviate it as well.

Also check and make sure the heat shields on your exhaust up by the Y pipe aren't loose. I had to put hose clamps around all of mine, the welds broke and they made all kinds of noise.

mine sounded the same way, i took it off, put a slight bend in it and put it back on. when you put it in a bind it won't make that pressure relief sound, it just needs alittle tension on it.

but if that's not it, double check your plugs, just in case.
