I have a '99 I30 Limited w/ a little over 38,000 original miles (engine and ATF) and live in Dallas, TX. Did a pan drop/filter replacement and refill w/syn ATF @ 10,000 miles. I'm about to take it in for a full fluid exchange w/ Mobil 1 ATF. I plan to also install an aftermarket ATF cooler. The B&M looks good. I've seen reference to the 70264 (and 70268) and wondered if it'll fit in the I30. The size is 11"x6"x1-1/2". Does anyone have any ideas on installation location and/or tips? Is another model/brand better for the I30? The aforemention part # seems to come up regarding the Q45. I haven't found any posts re: the I30. Also, should I do another ATF filter replacement before the exchange, just after, wait about 10k, or not at all? Last question: do I need any additives to the Mobil 1? Thanks for all your help...
