Removing l  Gearbox removed –  Mark the installation position of the selector lever on the gearbox -A- with respect to the selector shaft in waterproof ink.   Note t  Marking is essential, as the selector lever on the gearbox -A- is mounted with a 180° offset on certain models such as the Audi A8. t  The marking is to ensure that installation is performed correctly. –  Screw out the bolt -B- and lift off the selector lever on the gearbox -A-.

Caution Risk of damage to selector shaft (shown here with hydraulic control assembly removed). t  The selector shaft is not to be pressed into or pulled out of the gearbox. t  The shifting cam -1- at the selector shaft will break off if a load is applied to the selector shaft at the top or bottom. t  The gearbox must be replaced if the shifting cam is damaged.

–  Screw the nut -T40188/1- onto the extractor -T40188/2-. –  Fit the extractor -T40188/2- over the selector shaft. –  At the same time, press the extractor -T40188/2- firmly into the oil seal -A--arrow 1- and screw in -arrow 2-.   Note t  Greater force can be exerted by hand in the direction of -arrow 1-, as the nut -T40188/1- has been screwed onto the extractor -T40188/2-. t  The extractor -T40188/2- cuts into the oil seal -A-. t  Take care not to damage the sealing surface at the gearbox and the selector shaft. l  The extractor -T40188/2- must be seated extremely firmly in the oil seal. If necessary, press in the extractor -T40188/2- several times and screw in again.

–  Fit the cross-piece -T40188- and align horizontally with the screw feet on the side. l  The cross-piece -T40188- must be aligned such that the nut -T40188/1- can rest flat. l  It is essential to maintain the distance -x- of approx. 8 mm between the bottom edge of the cross-piece and the extractor -T40188/2-. If necessary, fit packing plates as spacers between the gearbox and screw feet.   Note The spacing is necessary to enable the oil seal to be pulled up to the cross-piece. The extractor -T40188/2- will be damaged if it already makes contact with the cross-piece prior to full extraction of the oil seal. –  Screw on the nut -T40188/1- and extract the oil seal for the selector shaft -A-. –  Clean the opening and extract any swarf.

Installing –  Lightly lubricate outer circumference of new oil seal with ATF. –  Slip new oil seal over selector shaft and press in. –  Use tube -VW 418 A- to drive home oil seal.
