General description (Audi 100 C3)

The manual transmission can be 4-speed, or one of three 5-speed options, depending on the model.

The gearbox is bolted to the rear of the engine in the usual manner; due to the front wheel drive, the rotation is transmitted to the differential unit located on the front side of the gearbox and through the drive shafts to the front wheels. All forward gears have synchronizers, the reverse gear is obtained by engaging an additional intermediate gear with a synchronizer sleeve on the shaft of the 1st/2nd gear pinion and a spur gear on the input shaft.

The gear shift is accomplished by a floor mounted lever, a single rod and a linkage attached to a shift rod mounted on the rear of the transmission. The shift rod engages a pin that engages other rods in a bearing housing.

When a transmission repair is needed, special attention must be paid to the costs, it is often more cost effective to replace it with a used transmission than to install new parts on the existing transmission. Differential repair is not covered, as it requires special equipment not available to the home mechanic.
