Magnetized Transmission Cooler Line Filter

I've been using a magnetized GoldPlug drain plug in my Sonata engine oil pan for a while.

Now I'm considering a magnetized transmission cooler line filter. MagneFine makes one. I just have to figure out what size transmission cooler lines we have.

Welcome to the Australian Magnefine Website

Anyone using one of these?
Any recommendations or installation do's and don'ts?

I'm going to drain and refill (2 times) the transmission fluid at 45K and I will be adding the mag filter then.
