gear selector switch

anybody replaced there gear selector switch. my bently shows that is pretty easy but I have ran into a problem with a bolt that has a linkage piece attached to it. this assembly is blocking the upper bolt that needs to come out to remove the assembly. It seems that there are different types of trannys that come in this car. I think I have a gm tranny. its a 95 touring.
the bolt assembly that is in the way seems as though it was pressed in or someting like that because it wont just come out. If you have done one you will know what im talking about. advice please.
