I have a 2010 Hyundai Elantra 4 cylinder with a automatic 4 speed transmission and 7,500 miles on it. The OM (Normal Service schedule) states to inspect ATF every 40,000 miles or 48 months while the Severe Service schedule states to replace the ATF every 60,000 . My driving is 80% suburb / city driving and 20% highway . When would you do your first ATF drain & Fill ? Points to consider : To wait 40,000 miles before first ATF inspection seems long to me . Also Hyundai SPIII ATF turns from red to light brown after initial use so unlike regular ATF fluid (that stays red) - what am I looking for with inspection and a paper towel (i.e. dark brown SPIII ? , bad smell , some other cue ?) Lastly , the 2010 Elantra has a transmission screen I believe instead of a filter . Wouldn't there be contaminants in the first several thousand miles you would want to get rid of OR does this transmission screen hold a lot of contaminants , shavings , etc. before getting clogged ? So , all things considered above - when would you do your first ATF change ?
