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?

All I have ever used since the 1980's. 40,000 trouble free miles on my 09 with AMSOIL in everything since about 5,000 miles. Never uses a drop of oil and I change oil once every 2 yrs. Stored winters....
