To begin, place the shifter in the 1st gear position. Then, remove the shifter boot and retainer at the control assembly. Install two drill bits into the alignment holes in the control assembly to hold it in 1st gear. Next, attach both shift cables to the control assembly using the studs and pin retainers, ensuring they are routed correctly and operate smoothly. Move to the transaxle and shift it into 1st gear by pushing the rail selector shaft down until you feel the resistance of the inhibitor spring, then rotate the shift lever counterclockwise. Insert the stud on the cable into the shift lever's slotted hole and tighten the retaining nut. Repeat this step for the select lever. Remove the drill bits from the control assembly and road test the car, checking for smooth shifting and engagement of each gear. Fine-tune the adjustment if necessary after the road test.
