sup guys. I recently did a tranny swap and new oem clutch. I will describe this noise as best as i can. its more of a rattle noise. its not a heatshield or exhaust noise because it doesnt happen when i rev it or anything. It happens when im driving through the gears you can hear the slight rattle but nothing too loud. AND then when i let my foot off the gas when decelerating, the rattle gets louder. This is all when driving not making turns so i dont think its an axle problem. Its not a throwout bearing either because there is no noise when i press it or depress it. noise only happens while driving. car shifts smooth and everything. Any ideas would be appreciated!!!

 

Axle not seated completely in the tranny?
