Looking a changing all of the drivetrain fluids out and switching over to either Redline or Royal Purple. I can not find the standard for the manual transmission fluid in the H3. In the manual for the H3, page 6-12, it say's "Manual Transmission Fluid (Gm Part No. U.S. 89021806, in Canada 89021807).". Well cool, now where and what the FU(K is the standard that GM is using for the fluid in this transmission.
