Cool Re: Metal shavings in a manual trans

Interestingly, I checked the oil in the SM465 as well and it seems to be overfilled by about a quart (same amount the aux trans was low). The np205 transfer case had the correct oil level.

Now I'm thinking it may have a bad input shaft seal on the main trans which could be allowing the oil to migrate from one to the other... I planned to rebuild the sm465 when it was out anyway, so I'll know what's going on when I tear them both down
