Turbo Buick Shifter Cable . 2004R 4 speed units. Works on Turbo and non turbo specific 2004R's. 1984-1987. We built this cable off of NOS GM. Then we dropped the trans with the cable hooked to the selector. It broke like any GM would. We told our manufacturer to fix it. Then we dropped the trans again with the cable hooked and it would not break. That si not the proper way to remove a transmission but we seen it plenty of times. This will be the last cable you buy.
