Bro hindi naman seguro magsisinungaling ang owners manual para sa PMS. It indicates to inspect (only) ATF every 100k km under normal driving condition. But under SEVERE driving condition (i.e. repeated short trips, towing trailer or climbing mountain frequently, driving on rough/dusty road) indicates to inspect every 40k km and replace every 80k km. My personal comment MUX automatic transmission is sealed type without dip stick and therefore you will check ATF only as scheduled per owners manual. For your reference On my 15k km ng mux ko nagpa check ako ng ATF sa shell at ang ATF color appearance ay clear RED na medyo pinkish. At saka kung mag palit ng ATF ay approx 7 quarts ang capacity if drain all, who knows kung tutuong may actual ATF replacement dahil ang nakacharged sayo ay 3 liters lang.
Peace po sa mga Isuzu sevice center...
