New to 4th gen KIA. I have a '12 Optima SX, 107K. Just did the messy ATF fluid change and level check. Looks like the trans has just the two cooler hoses from the front of the trans to the radiator. Any suggestions on where exactly to put a Magnefine 3/8" filter? I don't know which direction the flow is going. BTW thanks to Turbonut for other advice on this site.
