As long as it says CVT on it it will be fine with the cheap stuff. I replaced my 5R55W trans in my 02 mountaineer with a totally remanufactured one and used the trans fluid it called for but bought the walmart brand and it hasn't had a problem in almost 3 years. A lot of people swear by the name brand expensive stuff I'm not one of them and my trans will last just as long as their name brand trans fluid
