Car won't shift from park into reverse all of the time, without a couple of tries
I have a 1999 Buick Century. Last week I took the car in to have a coolant leak fixed. They replaced the intake gasket and thermostat. Since I got it back, there have been 2 or 3 times when the car would not go into reverse from park. I have to make several attempts to get it into reverse. My service engine light has also come on again. I am wondering if there could have been something that occurred while they were fixing the coolant leak that could now be causing my transmission issue?
