So I have a few issues, about me truck first... 04 f150 5.4 3v new engine new tranny..

I have had a clogged cat for a bit took a trip came back truck now when i hit the gas i hear a winding noise no codes except the clogged cat. I was thinking it's time for a clogged cat but someone was also saying it could be the torque converter, wouldnt that give me a code?

 

After a long and hard search I found a issue that someone else had on the net but with a solution this is exactly what mine is doing so im thinking that this is it... (pully and tensioner pully)
