Consumer Description

I have noticed that when it's very cold, the vehicle will not shift to the two highest gears (I think) until 20+ minutes into my trip, and that's with having auto-started the vehicle 10 minutes prior to getting in it. So it takes about 30 minutes for the vehicle to shift into whatever the two highest (I think) gears are. This morning, 20+ minutes into my trip, I was going 71mph while pushing 4,000rpms, and it wouldn't shift. The temperature outside is 1 degree fahrenheit. The same thing was happening when it was cold in December. That day I don't think it got above 0 degrees fahrenheit.
