mine has just developed a strange noise - when travelling at low speed ie. in slow moving traffic - get a grinding/clunk coming from both rear and front transmission somewhere - I assume something to do with the DCCD - any ideas ?

 

i had this on my my03 jdm sti.make sure the settings are on fully open(right back) or auto when moving slow,afaik this does happen! always got mine fully open.hope this helps!
