Jimm 1/1/20131) Climb inside the cab with an open-ended wrench set. Slide your fingers under the rubber boot on the floor of the cab. Inside the rubber boot is the stick shift. The stick shift attaches to the shifting cable on the top of the transmission.
2) Slide one open-end wrench over the nut and one over the head of the bolt. Hold the wrench with the nut in place as you loosen the bolt with the second wrench. Lift up to remove the stick shift.
3) Find the two locations the shift cable attaches to the shifting arm in your truck. Use an open-end wrench and remove the bolts connecting the shift cable in both places. Pull the cable out through the rubber boot.
4) Thread the new shift cable through the rubber boot and to the end of the shift arm. Reattach the cable with the bolts. Put the shift stick in place and tighten the bolt with the open-end wrenches.
5) Move the stick shift back and forth to check the movement from one gear to the next. If the movement is smooth and shifts every gear then put the rubber boot back in place.
