Having a problem with the shifter on my 93 900S 5 speed. The shifter has always been a little tough in reverse, but here lately it had gotten tougher. Right now I can put it in reverse and get the key out but it goes nowhere. Also both 1st and 2nd got tougher to get in and now they are non existent so I essentially seem to have a 3 speed. 3rd, 4th, and I think 5th, it happened in an area where I couldn't get up enough speed to try 5th. Any ideas?
