Hi all -

I'm about to change my transmission, transfer case, and differential fluid out for the 3rd time at 40k miles and wanted to get some input. I've had Amsoil Severe Gear 75W-90 in it for about 1.5 years without any issues. I'm getting an Exedy Twin HD clutch put in on my Evo X GSR soon and was considering what fluid to use. On a side note, I'm also looking into getting the ACT Monoloc one piece collar as well. I might just use Amsoil Severe Gear 75W-90 again for everything but wanted to get input from the community here.

I've seen some people swear by Diaqueen for the transfer case and differential, and others run a mixture of Redline or Amsoil for the transmission. I'm a fan of Amsoil as I've been using it on basically everything on my Evo X for a while without any issues. Any input or thoughts?

Thanks.

 

Save your money and use stock Diaqueen, it works fine

 

why are you changing your fluid so often? 3 times in 40K miles? that seems excessive.

 

What would be more reasonable?

 

isn't it recommended at 30K, 60K and 90K and so on?

I guess if you track it, it make sense to change it more often.

I run diaqueen in my two Evo's. My car sees track duty at 450whp, and the diaqueen does the trick.
