hi scotty ,I have a 2013 lexus es 350 and they say is a sealed transmission that don't need to change the transmission fluid ,what's your advise ,should I change anyway ,how many kilometres should I do if I change and should I flash too or not ,the car has only 45 thousand kilometres ,Canadian car

I would change it every 50 thousand miles anyway.

@ScottyKilmer. If the car manufacturer says that the transmission fluid is lifetime, that means that it should never be changed. I know you have 50 years of experience under your belt, but that's how a lot of modern cars are these days.

Many car manufacturers are using proprietary fluids these days so I understand where they are coming from they would rather declare it a lifetime fluid than deal with warranty claims from morons who put the wrong fluid and burned up the transmission
