any solutions for this problem would be greatly appreciated.
Most control boxes have the ability to either put the cables above or below the fulcrum of the control lever, also the cables may enter the control box from either the front or the rear. Some boxes have cable entry from below only, from under the panel and out of view. These will also have two possible hookup points, at least there is a 50/50 chance of getting it right every time! Assuming the cable has been replaced on the original entry point to the box, you have placed the shift cable on the wrong side of the fulcrum. Change the cable to the opposite side of the fulcrum and you will reverse the shift direction. There is not really any other possible cause other than you have placed a cable in the wrong place on re-assembly. And it is not that hard to do that - even when you have done it a lot!! :)
Just a thought from a breakdown within my head. The cable would have mounted either nearer the handle from the fulcrum of the lever or on the other side of the handle from the fulcrum of the lever(when you push the lever forward with it above it pulls the cable forward while if the cable was mounted below it would push the cable backwards. My guess is something is backwards in that regard. Just what I could put together from my imagination of how your system works.
