my mustang has 160k now and the trans fluid and filter have never been changed, this car has no dip stick which makes it hard to check the fluid. have no issues with the trans at this time, but in my mind I should change the fluid and filter.i have talked with other owners most tell me if its not broke don't fix it. some tell me it does not require a change. my question is should I change it
