06 plate Auto Gear Selector Problem

[chrisf1]

Hi again everyone I have terrible problems getting my selector out of Park on level ground once wrenched out all gears work and function as they should, I believed it was the release button under the gear knob so wasted my money on a solution advertised on ebay which gives a replacement button, bottom line to that is I could not get it back in, the car is still driving and after initial fight to get out of park works as it should, I have now ordered a complete selector but would like to know if the cable that connects it to the gear box requires adjustment or is it a standard size as the one I have ordered used does not come with cable and being as it is our only transport I dare not dismantle until I have a replacement any advice on this gratefully welcomed many thanks Chris
