Yes, I have posted this advice, as have several other people. Shop Manuals all state that "guide pins" should be used when installing a transmission. It took me many years (and many transmission removals/installs) before I decided to make my own "guide pins" (now I don't waste any swear words when installing an SM420).

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
