On my 1998 XJ8 the release that clicks when you put your foot on the brake and allows you to move the gear selector ist not werking. Please help!......There is a hole on the panel too.....and when a nimrod (which is what I feel like) is inserted into the hole, it will release from the "Park" position. Is this how I have to do it from now on....

 

sounds like the solenoid lock is dead, to get at it you have to dismantle the J gate selector and remove the 'ski slope' trim. You can then test it. If it works on a battery, then it'll be either connection/switch/loom.

 

2 things come to mind.

Brake light switch faulty/failed.

'In Park' micro switch faulty or the little metal arm fell off.
