Hello All and Happy New Year, Kev posted a repair article I wrote documenting my journey to resolve an annoying driveline vibration while overdrive is engaged. Since the article is a supplement to 1940 Service Letter, Vol 14, Number 11, it is now listed there along with the rest of the Volume 14 letters; you can find it here: (https://www.packardinfo.com/xoops/html/downloads/SC/SL-VOL14NO11_ADDENDUM.pdf)
It hope it helps for anyone who has a 1940 transmission with R9 overdrive installed and has experienced an annoying vibration. If you notice any errors or content missing, please let me know.
