Reverse Gear
WARNING: This page is about a different car, the 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The reverse idler gears are mounted on a reverse idler gear shaft supported at one end in the flywheel housing and at the other in the transaxle case. Because the reverse idler gears rotate on the reverse idler gear shaft, they are supported by 2 sets of reverse idler gear needle bearings to prevent metal-to-metal contact and wear.
When the reverse idler coupling sleeve and hub engage the reverse idler gear, it reverses the power flow to the mainshaft.
