Cytron / steering help

I just upgraded my system from a phidgets motor to a hydraforce hydraulic setup. But since swapping it out my current problem is that my auto steer is not engaging. However if i engage autosteer and then just tap either the MA or MB button on the cytron then the tractor steers and follows the line as it should, until disengaged. Then upon re-engaing auto steer the tractor does nothing, again unless i tap either the MA or MB button and then it works as normal. I swapped out my cytron and still no better. Anyone have any idea of where this issue would be coming from?
