Truck was on lift to change the oil last week, guy said the rear seal going out. Is this common at 77k? Can this wait til I get the tranny upgraded in March? Here are some pics. Also the botton of the bell housing has tranny fluid again. Dealer replacedthe front bell housing because they said the housing had a flaw in cast design... Is there something else wrong? It shifts fine. I dont have any drops on the garage floor. Been like this forever... Just checking to see if I need to park it til March or what.
