So I have this civic 03 coupe ex that had a Japanese motor installed and a month after when driving on first second or Reverse @ high Rpms I hear rattling noise by engine/trans area?? Anything on this ??

check motor mounts , I can't think of any panels or shrouds in that area but take a look , pop the hood and rev the engine

NDNV

Loose exhaust heat shield(s)?

it sounds like inside the bell housing, I haven’t put in the air but I will soon. I just thought it was odd cuz it only does it on first and second gear when I let off the throttle and it’s in those gear. Kinda sounds like lose fly wheel.

Could be a bad throwout bearing, or something could be loose in there, any vibration in the clutch pedal at any time?

No noise when the clutch is in. it’s only either on de acceleration or acceleration on first and second gear mainly. Im going to put in the air soon and go from there. Hopefully something lose.

So I found out it’s inside the transmission, bearing noise. I will take apart my tranny and rebuild. Does anyone know any good places to get transmission rebuild kit for good price ? Or should I buy bew tranny ?
