I just did a transmission fluid and filter change along with differential fluid at 99,000 miles just to give some background.
When I am between 35 to 40 mph and I take my foot off the gas there is a weird humming that was not there before I changed the fluid. Sometimes it happens at 25 mph but its always wen my foot is off the gas.
Also when I turn off the car there is a squeaking sound for half a second almost like a less high pitch mower belt that has slack in it engaging (anyone that has had this knows exactly what I am talking about).
Thanks in advance for your responses. This forum is a great source of knowledge.
