I just picked up an '89 RX-7 GXL, and need some help. I can't get the thing to shift into neutral. I can get 5th or R, but I need it to go into neutral (makes it easier to push around). Is this a shifter malfunction or an internal malfunction?

I tried removing the shifter and manually pushing the socket around, still no luck finding neutral.

Any ideas appreciated.

Thanks
Eddie
