Believe it or not you can not check the transmission oil on a 2008 Tundra with a 5.7 leader engine. It is designed to go 100,000 miles before servicing and IT MUST BY DONE BY THE DEALER. it has to be brought up to a certain temperature and need a special tool to check it. Talk to a Toyota service manager if you don't believe me.
I had a conversation with a service manager and he said "You can't believe how many people drain the transmission and then can't figure out how to refill it and have to tow it back here to get it fixed."
Also look in your "Owners Manual" and you will not find anything on servicing the transmission by the owner.
You should change your automatic transmission fluid in Toyota gearbox at least after every 30,000 miles.
If it is an automatic transmission every 30 thousand miles.
Toyota recommends every 5,000 miles but you could do it sooner if desired
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.
ten thousand miles
50,000 mi
Urine because you can change the fluids often.
Every 15,000 miles.
You must replace the belt every 90,000 miles. Warning:This is an interference engine.
