Which Redline trans fluid?

[Myke456@aol.com]

I just wanna get the right stuff the first time.

Ordered Redline manual trans fluid today from Imparts along with other stuff,
I described my vehicle-87 5kTQ, they said use the MTL4, so I went with it.

Then I remembered I saved phone number for Redline that I saw posted here
awhile back-called them and asked which fluid, they said MT90 is
correct.(??!??)

So I called Imparts back and changed it to MT90, but I'm left wondering. Can
anyone confirm this. The manual calls for GL4 type.

Thanks,
