I have a 1987 Buick Century and recently the gear selector broke. Not really actually broken, but when you go to put it into park the gear selector slowly floats toward it and actually doesn't go there. It stops somewhere between reverse and park and by morning time it does show park on the gear selector. Just to clarify, there is absolutely nothing wrong mechanically with the transmission, it still shifts into gear, you just cant tell by the selector the proper gear, you have to judge by shifting/counting, etc.
If anyone can tell me what parts make up the selector and what is broken in there or how to fix it, please help, it would be greatly appreciated. Also, if something needs replaced where to get the parts...
