Manual has multiple suggestions and have seen multiple opinions. What oil do y'all recommend for the 435 4 speed manual trans?

Some of the variances in opinions pertain to what temperatures the vehicle will be driven in the most. What works best in 100 degree Summer heat may not be a good choice for below freezing temps.

Exactly.
But since any location has a vast difference between summer and winter temps, a person has to decide on an oil that will work over the entire range, unless they plan to change it seasonally - PITA!!!!
