Went out and started my wife's 2012 Edge this morning and the temperature was -17. Warmed car up for 15 minutes and went to move it and the brakes were froze. Wouldn't back up so I went forward and with a little gas it broke free. As I tried to back it out of the garage the trans started to slip but was able to get it out. When I went to go forward it acted like it was going in and out of gear and slipping. Put it in reverse and backed up ok, not perfect. So I pulled up again to the same issues as before. So I backed it into the garage and parked and drove her to work like I knew I should have anyways. Anyone care to guess what I may done/messed up this morning? car has 113,000 miles. assuming this won't be a cheap fix.
