2-4 Band
WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
The 2-4 band is used to shift the transaxle into second and fourth gear (O/D). It is operated by the 2-4 servo. The 2-4 band holds the primary sun gear stationary by locking it to the transaxle case.
