This probably won't be an issue with you, but in FL, with the heat, the tranny does not like the II. I have ran both, first 1, then I tried the 2, I went back to the 1. The differences are:

BG I: Works better when warmed up.

BG II: Works better cool (the first 5 mins. of driving in FL), once warmed its too slick.

 

Only using Amsoil in my engine and trans. TC and Diff is OE fluid.

 

Dam i really need to find out what fluid the shop put in my car when the put my car back together. After installing the stroker.

 

Well actually it will be an issue for me due to the fact that I will be stationed in Tampa for a year so I will have to put this into consideration. Thanks for the heads up.

 

Amsoil fluids, front to back.

 

I was going to buy some Amsoil today, but NAPA didn't have the correct one. All they had was the synchomesh.

 

I haven't tried AMSOIL tranny fluid yet, but I hear its even better than BG II. BG, BG II, and Pennzoil synchromesh have acceptable fluids to use in the Evo transmission (5speed), and imho are much better than the OEM diaqueen fluid (ask anyone who races their Evo.)

 

I can't stand when people say only use Mitstubishi factory fluids. As long as you use GL-4 your fine. Shep uses a mixture of bgII and mt-90 and AMS uses all redline. I had my tranny, transfercase, and rear diff. fluid changed at AMS. They put mt-90 in the transmission, lightweight shockproof in the transfercase, and heavyweight shockproof in the rear diff. They also added some special additive to the rear diff. My car shifts like butter now.

 

Yep, that Redline wax in the small passages in the transmission works great, if you're trying to plug them up....

 

i use redline mt90 in trans and it feels smooth. shifts like butter! haha
