So I installed my twm short shifter and I don't seem to be able to engage the gears on the left well (1st, 2nd). I tried flipping the spring around on the guide pin but still no luck. I also popped the hood and checked the shifter cables and everything seems to be intact. Anyone have a similar issue after a short shift install? The shifting is quite stiff and right now I'm using 3,4,5,R to get around.
