Well, could be a lot of things that cause the light to come on - its a rather complex trans control system. Does it show any symptoms? If its stuck in a high gear (4th as I recall - should say in the owners manual) its in "limp mode". This could be caused by something that the computer is confused about, but most likely the trans is cooked. How many miles on it? These cars 92-95 actually had a light-duty General Motors trans, the 4l30e, and in my experience, if they aren't maintained REALLY well, like fluid & filter change every 40,000 they wont make it much past about 125,000 - 150,000 miles. Good Luck!
