My 90 Blazer is now trail ready with completion of axle upgrades and lift/locker adds. My only nagging problem is a leaking NP241. It was originally leaking from the tailshaft, but after replacing the rear seal it now seems to be leaking from somewhere high in the case. The weird thing is I never have to add fluid, and when I changed driveshafts this weekend to the new longer shaft it seemed to be overfilled - when I pulled the fill cap off fluid ran out. I checked the tranny, and it might be down a pint since I changed the fluid 2000 miles ago, but no more then that. Question is, is it possible that the tranny is leaking out of the rear seal and into the transfer case under pressure?
