I was told a few days ago that it is good to overfill the NV 4500 by a quart or so, is this true? I have always filled mine to the normal level and I have over 200,000 miles on it and it is just now having synchro issues, I was just wondering if overfilling it would help or if you could have some problems with seals leaking because of a higher oil level.
thanks,
