Recommend Automatic Transmission fluid

I appreciate your response. I bought a Merc Marauder and she wanted a Tiburon GT lol, my experience with Hyundai told me to find a place to ask since (your absolutely right) a new tranny isn't in the budget. Asked a service mngr I know at the local dealer and he insisted on Hyundai tranny fluid and another buddy said Castrol would be fine and I wasn't comfortable with that so I figured I'd make sure asking here. Fluid is NOT red, trans is slipping so I know it's time to change it, bought at 90k miles and now has 118k, quick little car, she's happy so you know how that goes lol, thx for the clarification, like you said it's definitely worth keeping the trans happy, thx again!

You're welcome , good luck.
