Duramax, warm up time
I'm considering a 2015 Duramax that a friend is selling that is pristine and well maintained. He drives a lot, it already has 115,000 miles on it. I on the other hand have a short commute only 6 m...

Special DPF Driver Messages
If the vehicle is used for numerous short trips or extended slow-speed operation, the engine computer may not be able to adequately heat up the exhaust system to clean the DPF effectively. The engine computer has been designed to continuously monitor the condition of the DPF. When the engine computer detects that the DPF is nearly full of particulates and that the vehicle is not being operated in a manner that would allow effective automatic DPF cleaning, the Driver In Brief Information Center will display the message CLEANING EXHAUST FILTER KEEP DRIVING UNTIL MESSAGE IS CLEARED.If the vehicle continues to be driven in a manner that prevents effective DPF cleaning, the DPF will become plugged with particulates. If this occurs, the engine computer will turn on the service engine soon light in the instrument cluster and the DIC will display the message ENGINE POWER IS REDUCED.See Diesel Particulate Filter on page 9-11 and Engine Power Messages on page 5-11

Initial Drive Information Transmission Cold Operation
When temperatures are very cold,the transmission will prevent certain operations to protect against damage. The information below shows shift range availability based on transmission oil temperature:All shift ranges available at 25°C ( 13°F) or above.2 (Second) and 3 (Third) shift ranges only at 35°C ( 31°F) to 25°C ( 13°F).2 (Second) shift range only at 35°C ( 31°F) or lower.Torque converter clutch operation will also be prevented when air or transmission oil temperatures are below certain levels.In Brief For areas where ambient temperatures are below 40°C( 40°F), use synthetic transmission fluid approved to Allison®Transmission specification TES-295. See Recommended Fluids and Lubricants on page 11-10 and Automatic Transmission Fluid on page 10-10.
FYI, I very seldom "warm up" my duly. If I do, it's to warm the cab in the coldest of weather so I won't freeze to pieces driving.
I've never experienced any issues with DPF. Quite frankly, I absolutely cannot tell when the DPF is cleaning itself.
