So long story short, we had a HUGE snow storm and I was going to have to go up a steep hill on the way home. Other cars are in the ditch so I thought I'd just drop it into 4LO and drive up the hill. I was in panic mode and forgot to put it in neutral before putting it in 4 LO, I was in park. Now my 4LO indicator on the dash is on all the time even if I out it in 2WD, plus my ATP light is on. Have I ruined it?
