It might be nothing but when I was checking the bolts for tightness on my AAM spacer after retighting a few bolts I started the car and it was idleing with the AC off, not in gear, the fan wasn't running, i noticed an odd sequence of sounds.

it was a click then a cliunk... at random intervals sometimes within seconds other times it would be a min between then but the two sounds were always approx 1 sec apart? Seemed to be commin from the tranny. Wondering what it could be.

 

Any ideas???
