Some 2017-2019 Colorado and Canyon models equipped with the 6-speed manual transmission (RPO N8D) may have a rattle sound coming from the transmission shift lever. The sound may be due to a loose shift lever set screw (Fig. 17, #1) or rivet (Fig. 17, #2) in the shift lever.
Fig. 17
Verify that the shift lever set screw is loose or the rivet holding the two-piece shift lever together is loose. If there is a noise from the shift lever, check the torque of the set screw. The torque specification is 80 in.-lbs. If the set screw is loose, remove the screw, clean the threads, and apply blue Loctite. Torque the screw to specification.
If the set screw is at or above the proper torque, tap the end of the rivet and listen for a noise or check for free movement of the rivet. To help isolate the rivet as the source of the rattle sound, wrap tape around the shift lever to cover the rivet. If the wrapped tape eliminates the sound, replace the shift lever.

The condition is on models equipped with a manual transmission. The article has been updated.
Is this accurate. I’m not familiar with the Colorado/Canyon having a set screw on the automatic transmission shift lever.
