Yesterday it was around 10 degrees out I didn't plug my truck in all night and it was easily in the single digits. So I started it VERY hard start. Let it idle for 5 mins and drove off to work. I got maybe 200ft down the road and the OD light started flashing so i let off I hard to turn anyway, so I slow down turn and its fine the rest of then30 min drive.
Get to work and again its still 10 outside my truck sat for 12 hours out in the cold not plugged in, this time I got a little further but I didn't get to go over 20 as I was leaving town. still a very very hard start, felt like the trans wanted to drive when I had the brakes on but this time the light flashed at me only 2 or 3 times then stopped. again after that everything is normal.
WTF

Its under warranty, but I'm in NY and the shop is in SC
