So a friend of mine has a 96 Pontiac Bonneville. For years he's had a problem with the transmission. When the car is cold, it won't shift out of park. He has to wait for the car to warm up for the transmission to work. Keep in mind, this isn't really dependent on the weather, although it takes less time in the summer than it does in the winter. What exactly would cause something like this? His mechanic says he can't find anything wrong with it at all. I'm curious.
