My gear shift indicator had been stuck in one spot for a couple of years but only just identified by GM as being an issue. I got used to counting gears to change & most times I was correct!! I was told it would be a 1/2 day appointment & when I went in found it would be much quicker. It was only an hour or so, I had a coffee & read a book & I was very comfortable. All is now resolved & I will see you again shortly to change to my winter tires. thanks
