Knocking sound
 

I discovered a little knocking sound comming somewhere from the engine...I think, The funny part is it doesn't knock until i engage a transmission and back, then it starts knocking, and the knocking stops on the higher RPM, above 1000. Doesn't sound like the flexplate issue.

Please help

Are you sure it isn't just the heat sheild rattle???

I checked everything, shields, any lose parts etc. it comming somewhere from the engine or bellhousing area, and it doesn't sound like a tranny ether.

How would i know that it is not a main berring or something serious?

a main bearing would knock even if it wasn't in gear... especially on start up. I think it is either a loose torque converter bolt or a cracked flex plate.
