2007 NBS Transmisson Smell ? - 10/1/2007 7:35:50 PM    Rod Man   Posts: 14 Joined: 5/26/2006 Status: offline Hey Guys, I just bought a new 2007 NBS Silverado with the 4.8 engine, 342 rearend it's the W/T edition with the LS package. well my question is it has 300 miles on it now and i smell something like hot transmission fluid after driving and getting it hot. i pulled a 14ft. box trailer empty about 15 miles tonight and when i get home you could smell that trans fluid even my wife smelled it. the computer said trans temp was 196 degrees is this normal for a new truck? is it just burning off the new ? and what's normal operating temp for the transmission ? Thanks, Rodney Post #: 1

I would recommend having a tranny cooler (GM part #19171483) installed if you plan on using it to tow regularly The hot burning odor is probably just the Cosmoline preservative (that is applied to the undercarriage prior to leaving the factory) burning off the exhaust system and nothing to worry about, it should go away soon.
