Not sure the reasoning for this button? Please enlighten me if you can. I know it's easy to bump if ur changing your oil filter. It doesn't allow you to use reverse or 5th and 6th gears. Only name for it I came up with is linkage limiter. Would like to know the purpose of it?

I am going to take a SWAG that it is the lock to center the transmission in gear for gear shift installation/adjustment. VW's have a similar locking mechanism.
