So i've tried searching with only limited success, I was wondering what everybody uses for their trans, axle, T-case ETC. And why? I plan on changing all my fluids next week and I've got way more options than I need. Also, I have a slight grind going into third gear. Is there a fluid out there that will help to remedy this problem? thanks for the help.

 

Diaqueen.

 

I use Redline. They are popular among the racing crowd. Plenty of guys I know who race their M3 or Porsche use this stuff. Check out their website. They actually have an entire fluid kit for the Evo.

 

Searched through and found pen syncromesh is good so i used on mine. It feels way better than stock fluid. But still getting grind when i shift fast into 5th gear(no grind in normal drive)

 

That's kind of odd. I don't know if I just force my 2-3 shifts too much but I don't feel a grind at high revs. only when driving normally.
And this diaqueen? HUH?

 

Diaqueen is the stock OEM fluid. It's not bad stuff.

 

Try Silkolene..they have fluids for all purpose's
