I made a couple of clean 11.60 passes today, followed by a bunch of 12.2's and 12.4's because it was taking me 2-3 tries to shift into gear (1-2 or 2-3). It wasn't grinding, it was just completely locking me out.

This used to happen once in a blue moon, but today, it was happening in almost every pass; sometimes only 2nd gear, sometimes only 3rd gear, sometimes both. I'm also noticing a very notchy feeling right after my burnout. Shifing thru the gears during staging definitely helped, but didn't completely eliminate the problem.

This is for a T45, shifting at 6200 rpms. At lower rpms (< 6000) and regular driving it shifts like butter. Any ideas?

-Clutch cable/Quadrant? Mine is stock -I know that the stock set-up can be adjusted by pulling back on the pedal, but that's something I forgot to try. It may have been something as simple as that.

-Tranny fluid change? -I'm using Redline D4 ATF, but it's been in there for 60 passes
