I have a 2003 Toyota Tacoma Double Cab 4x4 auto trans. Everytime I come to a complete stop it makes a low thumping sound of sorts. I don't suspect it is a defect. I think it is normal. It sounds as if something is disengaging.
Any ideas what it is and if it should be looked at by a technician? My wife is concerned about it and I have procrastinated finding out the cause.
