Questions for you guys who know this thing! My 94 Runner used to have the 340H Auto trans but it now has the 5spd swap done to it so do I now use 75W-90 GL-4 gear oil or ATF?

Thanks.

 

If it is a gear or chain drive case, use gear oil:

What if its warp drive?

 

haha,

i use redline mt90 and have no complaints about it (in trans and transfer)

 

i dont think any manual transmission except MAYBE a newer honda car uses atf.

 

My '04 GTO with the Tremec T56 uses ATF. What truck did your manual tranny come from?

That's funny......there's a whole 'nother thread talking about this very thing.

Any recommendation on manual tranny fluid that is good from 0-110 degrees? This is an issue in Denver as we have extreme temp swings, and my tranny is not happy in the cold. I want to get a fluid in there that is still comfortable in the cold.

 

MT90 redline

 

I've just replaced my fluid with Redline MT-90 and my transfer case fluid with their 75w-90 designed for the application. I am pretty happy with it so far...go to the redline website and read up about the different formulas.

 

It came from a 2nd Gen Truck with the R150F Trans. It looks to me that I'd be using the Redline mt-90.

 

Nope. The T5 in my '86 Mustang uses ATF, if you put gear oil in it it'll f*** up your tranny with a quickness.

Denver - just use 75w90. I put 80w90 in when I did my clutch over the summer, and it gets kinda stiff in the cold till the tranny is warm, but it's workable. 75w would be a lot better.

 

What about for the diff? Mine came with the ADD since it originally had a 340H trans in it.
