Pennzoil Platinum LV is the only Pennzoil ATF compatible with SP-IV transmissions. They screwed up, but I'm not surprised, at the chain shop I work at many times the computer tells me to put Dex III in transmissions that should not be filled with Dex III, including Kia/Hyundai transmissions. If the tech is competent they may have actually put the right stuff in vs what the work order says, I know I always do research before changing trans fluid and make sure the right stuff is put in, maybe ask to speak to the tech that worked on your car.
