Does this apply to SMG? 02?
No, E46 M3 6MT only and only certain years.

Smoother more traditional clutch operation. No harm to the transmission unless you like to "dump the clutch" too often. It which case you tranny is doomed anyway.

just changed mine out with a modified zeckhausen cdv. the clutch is a bit more "grabbier". i'll see how it shifts when i go home from work.

I found that when i did mine the biggest thing was that i could shift like i used to on other cars. It drove me nuts i felt like i was driving for the first time with that damn thing in there. Really some of us know how to shift and don't need a check valve to help us.
