Oil loses it's viscosity over time and also becomes contaminated also, so yes, change the tranny oil and filter.
All the fluids should be changed as suggested by the owners manual.
Engine oil, transmission oil, transfer case fluid, differential oil, engine coolant, p/steering fluid andbrake fluid.
That's all part of good vehicle maintenance.
