Searched and couldn't find it, some say to line up the marks but there isn't any, it has a cover over the front, AC Delco part.
I put it it the middle of the adjustment, scanner says neutral or whatever gear I select, but even moving it while watching, it doesn't change. TIA.

Shift Cable Adjustment

Position the steering column transmission shift lever to PARK (P).
Apply the parking brake.

Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the full mechanical stop position.

Slide the black retaining clip forward on the range select lever cable end. This will allow the white lock button to be pushed out.

Push the white lock button on the range select lever cable end out. This will free the metal core adjust body which is inside the cable end. Do not push the white lock button completely out.

Inspect the metal core adjust body on the cable end for dirt or debris that may restrict the travel. Remove any debris by washing the cable end, the metal core adjust body, and the white lock button with soap and water. If the travel of the metal core adjust body remains restricted after the cleaning, replace the cable assembly. Refer to Shift Cable Replacement .

Lower the vehicle.

Ensure that the parking brake is applied.

Turn ON the ignition switch.

Move the transmission shift lever from PARK (P) to 1 and back to PARK (P) ten times.

Place the steering column transmission shift lever in the Park (P) position.

Turn the ignition switch to the OFF position.

Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the mechanical stop position.

Push in the white lock button in order to secure the core adjuster body inside the range select lever cable end.

Slide the black retainer clip rearward over the cable end until it covers the white lock button. Lock the clip over the cable end.

Lower the vehicle.

Turn ON the ignition switch.

Ensure that all the transmission shift light positions (P, R, N, D, 3, 2, 1) engaged and illuminate. If you cannot perform this task, repeat the cable adjustment procedures.

Ensure that the engine starts in PARK (P) and in NEUTRAL (N) positions only. If the engine does not start in PARK (P) and in NEUTRAL (N), the Park/Neutral Position Switch may need adjustment. Refer to Park/Neutral

Position Switch Adjustment .

Turn the ignition switch to LOCK.

Ensure that the ignition key can only be removed with the transmission shift lever in the PARK (P) position.

Start the engine and check the vehicle transmission shifting. The range select lever cable is properly adjusted if the steering column shift light positions are the same as the transmission engagements.
