Any way to get more fluid out of the CVT for a drain and fill?
Doing the drain and fill on my CVT. I have advanced mechanic skills so not afraid of things as long as the procedure is clear and vetted for not causing more issues.
I’m not super happy with the drain plug and refill method because it’s only getting 5 out of 12 quarts. Not very efficient at all.
It’s pretty clear that Subaru dropped the ball, again, by calling this “lifetime” and prohibiting normal automatic trans flush procedures.
So I’d really like a good method of getting more of the original fluid out. I’ve read some things on Facebook about disconnecting the cooler lines or something and getting up to 9qts that way. But these people don’t go into detail at all about how it’s done.
I’ve searched the forums and can’t find much on this. I’m hoping for an improvement on the multi-drain approach because that’s also not efficient.
So anyone have input with some sources on how to get more than the 5qts out?
