Internal Shift Linkage
WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The G6M manual transaxle is shifted internally by 4 shift forks. The reverse gear shift fork shifts in and out of the reverse gear. The 1st/2nd, 3rd/4th and 5th/6th shift forks control all forward gear shifts.
