I don't think using MaxLife ATF is going to change their minds and the warranty is surely expired by now.

The 10/100 Hyundai warranty only applies to engine, engine accessories, and transmission. Catalytic converters are covered by the Federal Emission Defect & Performance Warranty, which is good for 8 years or 80K miles - whichever comes first. But don't let me rain on the parade. Carry on.

I am using maxlife in a kia spectra , no comparison maxlife is better in everyway. I think most failures after a change are pre existing problems that were just waiting to happen. And using a non manufacture fluid is a easy way out for the car company . Its up to you to battle them over warranty issue's

1)No. never changed my transmission fluid.
3)My memory is failing me on this one.. but SPIII and ATF +3 are both highly friction modified fluids more so than the original dexron 3/mercon.

When you said "I wont mention any horror stories about clutch material melting etc." it seemed as if you had heard of MaxLife causing AT damage...

So can anyone else verify the fact that ATF +3/+4 is similar to SPIII?
