Along with the over the road SAE50 manual fluids(usually GL4) and the OTR GL5 non-LSD 75w90's.
Plenty of stout choices in the GL4 and non-LSD GL5 gear oils.
Since there are NO identical transmissions, ALL OF THE FLUIDS I LISTED DO WELL IN EVERY TRANSMISSION THAT I'VE USED OR INSTALLED THEM IN. For the colder climates, go a little thinner if you have a shift issue.
