Automatic transmission fluid should be changed according to the manufacturer's suggestions. Many manufacturers suggest having the fluid changed at every 100,000 miles.
Transmission fluid (Civic CVT manual every 50,000mls,Transmission fluid (A/T or ?/T) auto every 30,000mls
Every 5000 miles.
The transmission fluid on a Toyota Sienna should be changed every 100,000 miles. This helps to prolong the life of the transmission and improve performance.
Usually you should change your transmission fluid after 60,000 miles, but to be safe you should check it after 30,000 miles and if it looks like it is low I would add some fluid.
It should be changed every 30,000 miles.

You should not have to unless you have a leak
It depends how much you Drive, how many Kilometres per year you do. Maybe every couple of Years it should be changed.
If it is a rear-wheel-drive vehicle you should see a transmission dipstick near the back of the engine. Transmissions are often checked with the engine running and in neutral but some vehicle manufacturers requre that their transmissions be checked with the engine off. Always have the vehicle parked on a level surface to check the transmission fluid. Transmission fluid should be bright red. If it has turned dark and smells burnt you might be having transmission problems. When automatic transmission clutches slip they produce heat that burns the fluid. You should never have a burnt smell to the transmission fluid. If the transmission still shifts ok you should have the fluid changed every 60,000 miles at least. Some manufacturers suggest more often. If all else fails, go to a full service gas station and ask them to check the transmission fluid and watch while they do it.
I'm not an expert on this subject, but I had a mechanic recently tell me that your transmission fluid should be flushed every 30,000 miles. Good transmission fluid should be a semi-transparent pinkish color. If you notice that it is discolored, dark, or has dark particles in it it probably needs to be flushed. You can always add fluid if there is room but this will only temporarily fix the problem since your transmission cycles the fluid and reuses it. Hope this helps! Chris
