You need an expensive scan tool or change the fluid twice. I changed again after 3 months.
I would suggest to install a high quality high temperature neodymium magnet in the reservoir too, it will keep abrasive particles trapped on it.
so hows the result after changing twice.
Everything was working fine even after the first change. I changed 2nd time to clear the old fluid as much as possible.
What should be the dimensions/ size of that magent for this small reservoir?
