I have a 95 GT Auto. I use the cruise as much as I can. Also in Overdrive! When I am on the highway it seems kick itself out of OD. It stays there probably 5-7 seconds, then goes back normal. I thought it just did it on the hills, but I realized it did it all the time. Does anyone know of why it does this? I am sure I left some key info out. Ask and I can give it to ya! Thanks!!
