missing 2nd gear at high rpm / WOT

Jsolo

7500 miles on the 2012 here. Started noticing slight notchyness in 3rd/4th, and going into 6th. No grinding, just doesn't glide into the gate like it did when new. Going to change out the MT fluid to redline mt-85 in the next week or so (will do the diff while im at it). We'll see if that smooths things out. More importantly, i'm hopeful it'll take care of the whining noise heard in lower gears and nonhighway speeds.

As for shifting 1-2 at or near redline, keep in mind you're asking alot. The rpm difference between the two gears for the same speed is some where along the lines of 3000 rpm. So unless you're letting them drop by that amount, the syncro's are have quite a bit of spin down to do.
