I notice, only when dead cold, first thing in AM, a LOT of engine
fan noise, and the shift points are way up, even under very light load.
(I don't belive in gooseing an engine till it's warm) After 2-3 min,
the fan/air noise settles down. Almost like the thermal clutch
on the fan works backwards. Not an exhaust sound on mine.
