I can now say, "BTDT" to the Amsoil in the 4kq tranny. I've used Amsoil engine and trans 
oil in many different rigs over a five-year period and never any trouble. But I just 
couldn't shift the Q as well as I thought should be able to.

I tried the MTL and it's much improved over the Amsoil GL2-5 75/90 I was using. 
Especially the first>second shift when cold (20-40 F, first few miles). I couldn't make 
that shift with the Ams. Interestingly, I was shipped the Redline 75-90 initially (wrong 
stuff). The bottle specifically mentioned not to use it in transmissions with copper 
synchros due to "reduced friction, blah, blah..."

The moral:  I recommend MTL over Amsoil for the transmission. I did leave the Amsoil in 
the rear diff.
