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.
P.S. To all who may be celebrating, have a happy holiday season! :-)
