Shifter hard to move left and right (sourced problem to shfter arms on top of tranny)

That thing is such a POS, I had to replace mine too!

Mine was seized bad. It was hurting my hand to try and move it around. I finally got it apart. I don't know if the bearing/bushing thing inside it corroded or what, but after a thorough sanding, cleaning, and lubing it's back to normal.
