grinding gears?

that would be bad…you use ATF in a t56

Just out curiousity, why is that? I heard several guys using gm syncromesh in their t56 to improve shifting. I’m assuming the friction modifier may wear components? Albeit the gear teeth are very hard, the grinding itself is going to do more damage.
