fluids change 43k

Cts 3.6 di early 2008, 43k miles. Car was used for short fast trips, so I am going to change fluids in AT, differential, engine coolant, brakes...
However, I am not sure which method for tranny fluid would be the best in this case. Should I deinstall the pan and change filter and just refill with new fluid or just drain and refill?
I am also looking for any voice convincing to not use GM fluids... Any recommendations?

Any recommendations regarding AT/cool/differential non-GM fluid manufacturers?
Transmission fluid is anything meeting Dextron VI standards. Coolant is Dexcool. Rear axle is 75W90 synthetic. If it's a limited slip axle, get a bottle of GM 1052358 additive.
