A833 with Twin/Triple Stick Shifters?
I don't know what makes you think this will work. You will NEVER be able to shift this quickly
1 to 2 shift is easy. Just move the 1 - 2 lever
To shift from 2 to 3 you must
1.......CAREFULLY move the 1 -2 shifter from 2 back to neutral without getting excited and shoving it back into 1
2........Take your hand off the 1 - 2 shift lever
3......Put your hand on the 3 - 4 shift lever
4.....Move the shifter into 3rd.
