I was driving today and an odd thing occured. I tried shifting from 3-4 @ 6000 rpms and I thought I completed the shift, but rather when I applied gas the car just reved straight up (I thought there was a limiter on the cars that wont let it past a certain rev...but .. it seemed to like higher in red) anyway, I look down and see that indeed, it looks like its in gear. I shifted to 5th...again high rpms then, and same effect in gear but no power transfered. So I retry 5th at a lower rpm 4500 and it goes in fine. Thoughts? I am guessing my clutch isnt completely engaging/disengaging; or I am not fully depressing the clutch properly maybe? I shift the same way in the lower gears and she seemed to work fine.
