On my subject car (110k miles)I have never changed the transmission fluid. Owners manual does not recommend changing except under severe service conditions. This car has led a pretty easy life service-wise. Half highway and half city miles with a gentle driver. Never had a transmission problem. The fluid seems clear but is developing a black tinge to it. Should I change this fluid out? I hesitate only because I've been told that changing the fluid with this many miles may create more problems than it prevents.

ON, Canada eh?
I would drop the pan and change the filter and oil. I just wouldn't flush the transmission as this might create problems. Then in 50K miles or when the fluid changes colour I would do it again... This would be more gentle on the system and less likely to quickly remove any crud that had built up and cause problems.

I agree that power flushes are more likely to cause an issue. They can use strong chemicals. Just do a filter and fluid exchange.

Get that oil out of there quickly if its BLACK? Do a drain and re-fill a couple of times until that fluid goes RED again. Get the Pennzoil gal. jugs @ Walmart, drain bolt on tranny pan. No need to drop this pan as there's just a metal screen in there.

A drop pan is a must because there is going to be tons of clutch material sticking to the bottom of the AT pan. So do a pan and filter, and then after a few miles, use the AT flush machine.
