Internal Shift Linkage
WARNING: This page is about a different car, the 2006 Mercury Milan and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The G5M manual transaxle is shifted internally by 3 shift forks. The 5th and reverse gear shifter fork shifts in and out of the 5th and reverse gears. The 1st/2nd and the 3rd/4th shift forks control all other forward gear shifts.
