GQ auto ATP problem

[Muzza]

Hi Guys.
I have a 92 GQ auto that I could not get out of park and the ATP light was on. By pressing the little pin at the base of the gear selector I was able to get it out of park and the ATP light went off but every time I now select park I have to depress the pin to get it out of park but the ATP light has never come on again since that first time.
Cheers

First thing to check, see if the brake lights are working, it they aren't that will be the problem, check for a blown fuse or faulty brake light switch.

Thanks Dak, thats exactly what it was. I had breifly hooked up someone elses trailer which must have had a different wireing configuration and blown the fuse.
Cheers
