hello mate.
the kick down cable at the gear box end has a crimped barrel on the end.this end of the cable slots in to the govoner quadrant which is located behinde the valve block.if the end of the cable has come off you would be able to pull the inner cable out.if the govoner has jammed this could account for the excess cable.the only way to access the cable is to drain the auto box,remove the sump,then drop the valve block,removing only the large torx headed bolts,this will give you access to the govoner and the cable.hope this helps if you need any more info pm me
