Hi all, I just installed an nv4500 that I got from a pickapart a few years ago, it looked to be a fresh rebuild when I bought it, but the DA's at the yard emptied the oil out of it.My Chilton's said 9.5 pints of oil so I put in 10 (5 quarts) of royal purple 75w90 synthetic. The trans did a little whining at first then settled down, but then I noticed oil around the shifter seal ( no shifter boot cover installed yet ). When I first noticed it seeping I checked the vent tube and it had been plugged by wasps so I unplugged it but the seeping is still happening (overheat vaporizing the oil?). Any knowledge about this would be appreciated.
