gonna be boostin 8-12 psi by end of summer, just wondering what tranny fluid would be best for me, i kno the manual trannys are finicky with fluid but idk about the auto ones, and i need this tranny to last until the swap. i was considering royal purple due to its prestige.

thanks for the help

 

The only fluid you should use is Hyundai fluid, just make sure to get a tranny cooler. One of the local GK guys is running two coolers on his setup.

 

Doesn't the car have a stock cooler? Part of the radiator?

 

New OEM fluid with an aux. tranny cooler.

 

It does but it doesn't do a good job lol. If you like to drive your car hard no matter your setup, a tranny cooler should be on your list.

 

Oem fluid would be got from the dealership?

 

Yes sir. I believe it was $7.67/qt when I got it from the dealer about 3 weeks ago.

 

Sounds about right. Our OEM fluids and Filters are very high quality. Sounds strange but its why there is TSBs on not using OEM stuff.

 

Thanks for all the info guys... any reliable places on getting a trans cooler?

 

If I were you I would get a transmission flush and run to auxiliary transmission coolers.
