5spd fluid
if you have a Mazda M5OD and it has miles on it I'd drain it. I, as well as others, run a 30w Synthetic motor oil in the trans with Lucas Oil stabilizer.... just a tad heavier than Dexron Trans fluid but not as heavy as 80w90 gear oil...
it will shift very smooth and get rid of the gritty shift feeling. That was the advice of a few trans rebuilders....
