So far Shifting with MTL-R is a little notchy when cold, but once it warms up it's smooth again like the Redline stuff. I've been getting 90F temperatures in my area lately and shifting isn't notchy at all driving for about an hour. IMO It still definitely feels better than the OEM stuff. Only had it for about 2500 miles so far. I used this because it was recommended on Bobstheoilguy.com comments and couple threads on vortex.
