The gear selector linkage in my 1974 Monte Carlo had developed lots of slack over the last 48 years so this past April 23, 2022, I did something about it. This video shows what I did…



Enjoy and let me know if you have any questions.

This is a follow-up to my original post.

After I replaced the worn transmission shift linkage parts, much of the loosy-goosy slack was taken up but there was still some noticeable and annoying looseness as can be seen in the original video at time 24:21 - 24:45. I suspected there was an issue with the selector and detent spring inside the transmission. I started documenting the repair after I dropped the pan and saw what you'll see in the video. Please note that I hadn't intended to record an "instructional" video so I didn't have a tripod, etc. The camera was hand-held and all the footage is "raw", i.e., unedited.



One thing I didn't mention in the video is when I dropped the pan and inspected everything, the nut on the inside of the transmission that holds the range selector lever (#330136) onto the selector shaft (#470107), didn't seem as tight as it should have been. After replacing the selector lever, when I tightened up the nut, I put the torque wrench on the nut on the outside of the shaft and a box wrench on the nut on theĀ inside so that both nuts would be properly torqued. I would expect this to prevent a repeat of this issue. Furthermore, I'll note to check the torque on those nuts whenever I do transmission service in the future.

As always, I hope this helps those with the same problem
