Has anyone ever found this type of marking on an automatic transmission? It looks like an arrow drawn to the hole where the fill tube is attatched to the bellhousing. Found it when I started cleaning the trans and was just curious.

Thanks,

While it would appear that the arrow is pointing to that specific hole, I believe this arrow was used mainly to make sure the new guy on the assembly line knew to have that end of the transmission point forward. After a few weeks when he got the hang of it, they would no longer need to use this mark anymore. Sorry...couldn't help myself. An no, I've never seen such a mark.
