Reverse Gear

WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

The reverse idler gear (300) is located on the reverse idler shaft and rotates on needle bearings. The reverse idler gear (300) engages with the input shaft (100) and with the reverse gear (310). Moving the reverse shift fork (320) rearward moves the reverse synchronizer sleeve (330). The synchronizer sleeve (330) slides on the spline of the reverse gear. The inner teeth on the synchronizer sleeve push against the synchronizer ring teeth, causing the synchronizer ring to contact, and the reverse gear (310) and the countershaft to match speeds. The synchronizer sleeve (330) then engages the selector teeth (340). The selector teeth are pressed on the countershaft (400). Power flow is now from the input shaft (100) to the reverse idler gear (300), to the reverse gear (310), through the synchronizer to the countershaft (400) and to the output shaft (150).
