Sealed Transmission.

I have good mechanical skills, I work in service at a large auto dealership (Toyota), but new to Mercedes. I am a little confused. reading on this forum about service on the sealed five speed auto trans on my 98 C230. Several contributors say have the fluid changed, several say do not. My particular car has 140,000 miles on it, is in exceptional condition and drives perfectly, literally a little old lady car which I got a heck of a deal on. One contributor said that changing the fluid at that kind of mileage if it works well may do more harm than good! Help.
Also sometimes the heater/air conditioning fan for the climate control sometimes starts to vary in speed by itself, up and down without any reason, although the system seems to work well. Truth to tell it could blow cooler in hot outside temps. Any ideas? Thanks, Phil.
