NP435 noise
Hey everyone at FTE just got a quick question I have a 68 F250 4x4 with a NP435 trans, 205 transfer case and of course a 390 w/ 4bbl intake any how my question is, under very light acceleration there is a kinda ringing noise it goes away under harder acceleration or absolute coast its present in all gears with or without clutch engagment I cannot feel any vibration being transmitted to shifter on transmission or transfer case. Doesn't seem to be causing severe damage just real anoying any suggestions most appreciated .
