Power Transfer Unit (PTU) for AWD system has a known seal leak. Transmission fluid leaks onto hot exhaust manifold and smelly smoke permeates cabin when vehicle comes to a stop. First attempt to repair leak was not successful, despite a TSB.
5580 mi
Second attempt to repair leaking seal in PTU. No problems after this fix...no gear oil leaking onto exhaust manifold ergo no nasty smell anymore!
39040 mi
PTU unit leaking oil on exhaust and smelling like burning gear oil. Replaced right axle and resealed unit. In extreme cold there would be a whining sound coming from the transmission area. Especially around 60 to 65km per hour. Turns out there was a TSB regarding the transmission cooler line rubbing against the frame transfering the noise.
