a904 whine noise

i recently rebuilt my a904 with all the performance goodies... I have a whine when in operation changes pitch with rpms,, , now, I know that is classic pump or converter whine, does in all gears,,, ie pump... but question... I have a PTC converter that was made for the combination. and blocked trans pump vent, and relocated to top and rear of case... as per tech articles on line here. I also have a a&a deep pan kit with there dropped p/up kit with o ring. modified valve body with TF-2 shift kit.... and the pump and everything specked out... no major wear visually seen either. don't recall it making any whine noise before I went thought it, just slipped real bad,, burnt bands, now that all this has been done, wondering if any of the modifications I have done may be causing the noise? I don't mind the noise,sounds pretty cool ,like a gear drive, just concerned if causing excessive wear in something... this is a fresh build no miles on it, does appear to shift ok. also have and external cooler plumbed into the radiator cooler as well with a spin on filter kit, before going back to transmission, k&n filter equivalent to ph8a..., spoke with Lynn at PTC and agreed it is not nraml and could be the converter, or the modifications to the valve body raising the pressure making noise.. any thoughts out there?
