I bought fulid, read some horror DIY stories here, bailed and let the dealer do a drain and fill for $322 all in.
still have the CVT fluid jugs on the floor of the garage. (will find someone’s subaru that needs green CVT juice, vs. my daily driver), I think yours takes fancier orange.
if you try to DIY make sure you follow the procedures keeping track of temps. (on mine they had to wait for it to cool down to 94 degrees F on the button,…if not too much or too little gets in)
print it off out of the free library (SLI seems to keep these safe and free,)
and I wish @Brucey would make a video showing how to safely get 100% like the pro-mechanics do, (using the cooler lines, but I would want someone that has done it successfully many times to actually do it on one of my cars).
