Gear selector on dash PRND123 issue

cashflow50 · September 1, 2017

2003 gmc Yukon 4.8L 2WD

Started ride placed gear selector to R (reverse) and my door locks intermittently locked and unlocked. I placed it in D (drive) and same thing...door locks locking and unlocking. I also noticed that the line underneath the D or R was missing. Baffled i pulled over and killed the engine. I then started her up again and there it is the line appear on all gears?????? Drove her home without any issues. What could be wrong? I saw a thread archived here called " Problem With Gear Selector" by 98silv71 and its similar to my issue. Need help. Please advise. thank you.

can you actually pull codes even though there aren't any?

where is the PNP (park neutral position) switch located on the tranny? or in some cases called NSBU (neutral start back up) switch. Where is it located?
