Input shaft: Removing and installing Check the tool and equipment equivalence table according to the applicability between Seat / VW / Audi / Skoda → Chapter Special tools and workshop equipment required

t  Extractor -T40050- Detaching   Note t  Observe the general repair instructions → Chapter. t  Cleaning norms when working on automatic gearbox. → Chapter l  Gearbox removed and mounted on assembly stand in vertical position → Chapter. –  Drain the ATF → Chapter. To do so, swivel gearbox into installation position (horizontal).   Note Gearbox must not be turned such that flange points downwards.

–  Remove bolts -arrows-. –  Using a plastic hammer, carefully knock cover for input shaft to separate it from gasket.

–  Put the puller -T40050- on the drive shaft of the gearbox. –  Check that puller -T40050- is positioned securely on input shaft. l  Retaining ring must be pushed all the way down. –  Pull input shaft together with cover and forward clutch out of gearbox housing -arrow- using puller -T40050-.

Caution t  Do not put down input shaft on the protruding oil pipe -arrow-, as oil pipe would then become damaged. t  A damaged oil pipe will cause drive-away problems or complete gearbox failure.   Caution The reverse gear clutch plates must not be removed from the gearbox housing. Installing Install in reverse order, observing following: –  Assess wear on gearbox components → Chapter. –  Clean sealing surfaces on gearbox housing and input shaft cover.

–  Check that all dowel sleeves -arrows- (for locating input shaft cover on gearbox housing) are securely fitted.

–  Renew axial sealing element -arrow-.   Note A sectional view of the axial sealing element is shown in order to illustrate the installation position. l  Installation position of the axial sealing element: Sealing lips face upwards towards input shaft cover. –  Place new paper gasket in position.

–  Align plates of reverse gear clutch using a straight-edge or similar. l  The teeth must be set exactly in line.

–  Check position of oil pipe -arrow- : l  With oil pipe fully inserted, distance -a- from end of oil pipe to input shaft should be approx. 11.5 mm. If the distance is less, the oil pipe may be damaged (the end could have broken off if the oil pipe was pushed in too far). If the distance is larger, the oil pipe is not pushed in far enough.   Caution t  Do not put down input shaft on the protruding oil pipe -arrow-, as oil pipe would then become damaged. t  A damaged oil pipe will cause drive-away problems or complete gearbox failure. –  Insert complete input shaft assembly in gearbox housing.

–  When doing this, rotate input shaft slightly in both directions -arrow- until all clutch plates have engaged. Also lift input shaft slightly at the same time. –  Just before the input shaft is fully in position, rotate it anti-clockwise over the last few millimetres so that it engages in the teeth of the helical intermediate gearing.

–  Tighten new bolts -arrows- diagonally in stages. –  Fill up with ATF → Chapter. –  After fitting the gearbox, check the ATF level and refill → Chapter. Tightening torque
