If it is the simple "removal of the center detent ball method"....then you should still have the regular shift pattern (unless the shifter sheet, or something else, is messed up), and also a "special" shift pattern to get it into and out of 2L. If somehow you got it into 2 low and are not using the correct pattern to get it out of 2L, then all the stick will do is move back and forth (it will be 2L in the "forward" position, and 2H in the "rearward" position)......if you move the shifter half way between 2L and 2H, then move it to the left to catch the "sweet spot" you can get it out of 2L. What you need to do to get it in or out of 2L is move the shifter halfway between the far right and far left position and catch both shift rails......then move the stick forward or backward (you can feel the gap between the shift rails when moving the stick left and right, if you put slight pressure forward (when going into the 2L pattern) or rearward (when shifting out of the 2L pattern) on the stick).
I'll try to post a few pics that explains what I am trying to say. The pics show how the shifter needs to be shifted to go in and out of 2L. I'll also post a pic of what the regular shift pattern looks like in comparison.
Ok, the first pic is the regular tcase shift pattern. The second pic shows how to shift into and out of the 2L position. The third pic shows what the pattern looks like, once you get into the 2L position.
You could also have the "H" shift pattern (PetroWorks, I think).
You could also have the "reverse S" shift pattern (Rocky Road, I think).
You should be able to check on either of their websites and it will explain how the shift pattern should work.
