Hot or cold, it doesn't feel like crap.
Amsoil doesn't make the proper viscosity for the X transmission. 75W-90 is too thick and will be very notchy and hard to shift when cold.
Use the OEM Mitsubishi Diaqueen 90W LSD & OEM Mitsubishi Diamond ATF SP3; same intervals as the transmission fluid (I do mine every 15k miles or so).

 

So Your basically saying, just go to dealer and buy all the fluids from them.

Fresh fluid is fresh fluid, if Mitsubishi uses them on our cars then obviously will be fine.
The most important I guess is to replace it every 15000 to 20000 miles.

Thanks

 

Amsoil is good stuff but the Redline mix is where its at.

 

My 30k is coming up and I need to do this too. I heard a lot of good things about the reline cocktail and I think I'm going to try it out. What exactly is the mixture I need to order?

 

What order do I fill the transmission in?? The whole bottle of mt 90 first or both mtl then the mt 90??

 

If you mix it before putting it in, it wouldn't matter, right?

 

 

Bought it from amazon for $47 shipped to my door. Friend helped me do it in half an hour

1qt - Redline MT-90 50304
2qt - Redline MTL 50204

 

guys does the diff and tranfsfer case use the same oill in evo 7 gsr/.

 

Only oem fluids for a drive train. I am using only stock fluids, and the car runs like a champ from day one.
And that is 3 years of racing. In my drive train everything is original. We just swapped the rear ayc out for a new rear diff, but that is only because i have a new ACD ecu.(aftermarket wont handle ayc, only mechanical diffs)and the ayc look good too. But it has been a lots of abuse and tq put on it at least 3 years now. Over 400 wtq for sure.

My suggestions is if you have a stockish car, stick with a oem fluids . My car never had anything in the car but mobil 1 and dealer fluids.

I use mt90 for tranny....makes shifting so smooth and crisp
