My brother is having some shifter trouble with the stiffness from old shifter cables. When that happened to me with the little 96 Cherokee, I replaced the cables with new cables. My brother has read that he can take an air compressor and set it at 30 pounds, put some oil in the hose, clamp it to the shifter hose, and force oil through the cables to fix the hard shifting. I never heard of that before.... Has anybody ever tried that and if so did it work or is he spinning his wheels? Thanks.
