Anyone else experience this? When dropping the truck off for service last Wednesday my fiancee mentioned that there's a burning rubber smell, esp after highway driving. I noted this on the drop-off sheet (both have busy schedules so we usually drop it off after hours). I stopped by the dealer the next day and the SA said the seal between the transmission (6spd MT) and transfer case was failing and needed to be replaced but had to be ordered so if we can drop it off again next Wednesday and they can have it all day Thursday to which I said fine. She said they topped off the fluid but I'm not sure if it was in the case or the tranny that was leaking as I never noticed and puddles or drips. Is this a common issue?
