It's weird and it only started doing this recently, if im at a stop light, and it turns green and I give it a little gas, when first gear gets to about 1200 rpms I can hear like a faint knocking/clicking sound then when it goes about 1500 rpms I dont hear it anymore, atleast thats what I think unless I cant hear it cause of my engine, and if I put it in neutral and rev it a little to about 1200 rpms the same RPMS I hear the knocking/clicking, then I dont hear it at all, only when its in drive, can anyone possibly help me out? cause im guessing its coming from the transmission or something simular to it since it only makes the knocking noise while in gear.
