Had several recommendations both on this forum and from other 10th gen owners and repair techs to drain the Honda MTF and put in some 75W90 and I am glad I did. When I drained the tranny it was like water literally that stuff is so thin and after putting in two quarts of Sta-Lube 75W90 Gear Oil (Yes it is GF-5 and labeled as safe for use in Manual Transmission and for LSD and Hypoid type Diffs and all that). Really as far as shifting, power, gas mileage I see no difference but its got to be lubricating the tranny better than the stock Honda fluid. Also noticed a nice glittery look of metal bits when I drained the fluid but seeing as its only got 700 miles on it I assume that is from the break in and maybe the few times I ground the gears a bit getting used to the new car. LOL
Anyway, thought I would share.
