Easy installation in my 1996 Trans Am. Works great and remedied the problem. The white plastic connectors literally pop off with the pry of a screwdriver and the new snaps back on by using a pair of pliers.

Brian K –
Great part that solved my automatic shifter issue on a 95 Camaro. I no longer need to punch the button on top of the gear shifter to move out of park… weird. The shifter now works like it just came out of the factory.
