Took the plunge yesterday. Put 6 quarts of Amsoil in....

AMSOIL - Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 (MTG)

It fixed all my shifting problems! Very impressed!

The truck shifts like BUTTER now!

Here is the oil. There is no way in hell i'd ever run ATF in one again.

AMSOIL Synthetic Automatic and Manual Transmission Fluid

How does this oil flows in the cooling lines.
I'm I right when I see the cooling lines on the 6 speed ZF transmissions.

My guy who works at ford said the pump is the same part number in the ZF6 from 04 to 09.

I am going to do this when I do my manual transmission change as well. I am curious, did you also change your transfer case fluid to the same 75w90? Or did you continue to use ATF in the transfer case?
