I took it to a shop today and he told me that its 100% not the engine, its coming from the torque converter/transmission

I also learned (not to my surprise) that this is not my original tranny.


My tranny is still shifting ok, and performs well, Has anyone had they're tranny make a knocking noise randomly? as far as I can tell, its not affecting its function

It pretty much does it at idle in park


thanks as always
