The best way to preserve tranny in good condition is to replace ATF a bit more often than WIS says, but without extravagance like with each engine oil change as it will not bring any benefits. Recommendation varied over years from 100.000 to 60.000 miles (in the meantime Volvo recommended lifetime fill in the same gearbox...). Generally speaking conditions in gearbox are much more friendly to oil than in engine, so degradation takes a lot more time. Something between 40.000 - 60.000 miles or 5 years would be fine for 5-spd. Aisin. It depends heavily on driving style and climate conditions - aggressive ride/frequent towing or high ambient temperature will degrade oil sooner. Don't experiment with oil or additives - use Mobil 3309/Toyota T-IV.
I recommend full oil changes as describes in WIS (link below) instead of a few partial changes, when the old fluid mixes with the new one. Full flush uses less oil and it's definitely better (no old/new mixing).

Unfortunately this gearbox has internal oil filter, which can only be changed when you take it apart. Proportional valves (SLU, SLS, SLT) are prone to dirt - sooner or later they will get stuck. They could be cleaned with home methods or replaced by new ones (Rostra claims that they succeed to make improved ones).
