Hi everybody!! I own a 2002 Hyundai Santa Fe, and it's been a good, reliable vehicle for me. I need to change the transmission fluid and the owner's manual states that I should use HYUNDAI GENUINE ATF or DIAMOND ATF SP-III or SK ATF SP-III. I called the Hyundai dealer I bought the vehicle from and asked if a "Dextron-III" type transmission fluid would be equivalent to those listed in the manual, and the man working in the parts department tersely informed me - "No, you have to use (the above mentioned brands) or Mitsubishi brand." I asked the price per quart and he said "$4.42". I think that's pretty steep for one quart of tranny fluid, and my gut feeling is that he was B.S.ing about there being no suitable equivalent. I didn't know Hyundai made their own transmission fluid. So I ask you out there, does anyone know if there is a less expensive, good quality, equivalent, tranny fluid for a 2002 Hyundai Santa Fe, or will the dealership be my only option?? Thanks for any help.
