Broken Shift Fork?
My '98 Explorer Sport was making a thunking sound, especially if you would coast (no gas) and then step on the gas. Worse going down hill. Took it in today and they said it is a broken shift fork. It has around $140k miles on it.
What is the cause of a broken shift fork? Could driving style or other driver error cause it? Or is it normal wear and tear? Thanks.
