You will never have such bad trans fluid when u NEVER do launch when u never drive like maniac .. In the past people were owning cars and NEVER EVER thought that they gonna replace trnas. fluid.. ONLY engine oil... Nowadays people doing all sht on internet just to make money from views so they will replace all possible nonsense on car.. When people suddenly shoot off from stop and step on it.. The trans gears making massive friction where micro chips happening from metals.. Nothing is undestroyable in the world.. If you never do all these car abuses your trans fluid will be STILL gold after 5 years or even 10 years of driving car...
