Okay- I'll avoid using the transmission additive.
Instead - I think I'll try another oil; The back of the Penzoil Synehcromesh says its GL3 rated. Shouldnt it be Gl4 rated, since the manual states Gl4 is required?
My local NAPA has Sta Lube Gear Oil GL4 85W-90; I want to go with this - however could the weight rating be problematic? The manual calls for 75W-90, and that seems pretty far off from the 75W-90 that is required. Would it make a difference?
I live in California, so the temperature is usually warm here, in case that makes a difference.
Thanks
