if you just want to change the filter just buy enough atf to fill up the new spin on filter.

the fluid does not need to be changed imo. but its really up to you

 

ok thanks...if i did wanna change it how much atf would i need to buy?

 

If you did a full flush, you'll want about 4 gallons on hand. May be a bit extra but better to be safe. If just doing a pan drain and refill, you need 2 gallon.
