NSG370 Transmission 10mm hole ?
Q: I found a lot of sand between the Transmission and Transfer Case which had enter though a 10 mm hole in the transmission near the gear detent where the xfer case join. The hole is facing forward 11 o'clock very close to the bolt holding the xfer case to the tranny. No breather hose or filter. no1 can explain what the hole is there for and just live with it ?
Must be there for a reason and most likey to equal the air-pressure when the drive shafts are spinning not to blow a seal. I have put a stainless steel guaze mesh over the hole as not to block the drain hole with crap coming in though the 10mm hole.
