These are the Aisin branded automatic transmissions. A Toyota joint venture.
I had one of these automatic transmission. I had a 2004 automobile that has one. This car is still going strong right now. "lifetime" automatic transmission fluid. No dipstick.
BUT.
Read the owners manual. On my car it states to change this "Lifetime" fluid at 60,000 miles under hard use and 100,000 miles on normal use. I had the fluid changed at 80,000 miles.
Read the manual.
As far as radiator goes. Never put any "cleaner" in it. Too many potential issues. Just do a gravity drain and refill with correct fluid and mixture. Dispose of properly. It's usually a simple petcock valve on bottom of radiator.
Be careful as some are plastic now.
Most (not all) engines today are aluminum alloy and rust is not that big of a factor. All radiators today are aluminum and again don't rust.
As stated above, fluid does break down over time.
I change antifreeze every 2 years. Cheap money for the satisfaction.
