Trans fluid

[Jdbuilds]

Good morning everyone! I just picked up my first speed a 2012. I’m going to swap both engine and trans fluid. Was wondering if anyone had experience with the valvoline 75w90 synthetic gear fluid. Just want to make the right call. Appreciate everyone

I've had goodluck with Torco RTF but if @JohnnyTightlips likes it you know its legit.

Don't forget to shake the bottles well before dumping, the additives like to settle.
