Just that. Kinda sounded like it was coming from the tranny. When I first noticed this noise is when I reinstalled my engine after repairing my pull start. I have adjusted the engine and slid it every way you can an nothing has fixed it the noise. When the truck is at idle, I can give it a bit of throttle and the noise goes away temporarily. Shortly after I heard this for the first time last week I tore out my spur gear and found the bearings and clutch on the engine were toast so I figures that is where the noise was coming from. Since I have installed new bearings, 3pc clutch, bell, and spur. Truck acts fine, just still has this noise.
Any and all help is appreciated.
