When im accelerating I hear a little whistle sound not too loud but u can hear it. But when I deaccelerated in 5th, 4th, and 3rd gear all I hear is grinding and rattle like sound. But when I push in the the clutch to shift it goes way unless im down shifting instead of breaking. Also when I let of the pedal I deaccelerated pretty fast then normal I believe. I changed the clutch and transfer case last year this time and had a manufacturer transmission put in july. Will post video of noise.
