Have a 2009 EXL not ready for a flush yet but don't want to wait the thousands and thousands of miles the manual suggests either. At what mileage have some of you folks done your first flush and/or change at? I'm thinking maybe around 25-K is adequate. Would have my dealer do it.

 

Auto tranny? Just do a drain/fill - don't "power-flush" it. 25k or 30k sounds reasonable, then judge the NEXT one based on how dirty the drained fluid is.
