Procedure l  Gearbox removed   Note t  Observe the general repair instructions → Chapter. t  Rules for cleanliness when working on the automatic gearbox → Chapter. –  Remove input shaft → Chapter. –  Remove cover from input shaft → Chapter.

–  Set down input shaft on assembly tool -T10219/1-. –  Use two screwdrivers -arrows- to carefully lift pressure plate with piston.

To prevent damage:   Caution l  The inner contact and sealing surfaces -arrow A- of the pressure plate and the piston -arrow C- must not be allowed to make contact with the shaft on removal/installation. l  The contact and sealing surfaces must not exhibit the slightest signs of damage such as scratches or scoring caused by dismantling/assembly. l  In the event of damage, the pressure plate or piston must be renewed.

–  Carefully guide the pressure plate -1- with piston -2- upwards over the shaft -3-. l  When doing so, the inner contact surfaces of the pressure plate -1- and of the piston -2- must not make contact with the shaft.

Removing clutch pack –  Remove corrugated washer -5- (washer must be re-used). –  Take upper shim -4- out of input shaft cylinder -A-. –  Measure thickness of shim -4- and note down value. –  Take all friction plates -2- and outer plates -3- out of input shaft cylinder -A-. –  Remove bottom shim -1- from input shaft cylinder -A-. –  Measure thickness of shim -1- and note down value.   Caution l  Always renew old used shims, outer plates and friction plates. They must not be re-installed otherwise proper operation of the input shaft cannot be assured (due to the worn surface). l  The corrugated washer must be re-used. Assembling input shaft   Caution Assess wear on gearbox components prior to assembly → Chapter. –  Replace the bearing “A” (ball bearing for input shaft) in the input shaft cover → Chapter. –  Adjust input shaft and determine clearance → Chapter.   Caution l  Always renew old used shims, outer plates and friction plates. They must not be re-installed otherwise proper operation of the input shaft cannot be assured (due to the worn surface). l  The corrugated washer must be re-used.

–  Set down input shaft on assembly tool -T10219/1-.

–  Insert chosen lower shim -1- in input shaft cylinder -A-. –  Now build up the clutch pack by alternately inserting one friction plate -2- (total of 6) followed by one outer plate -3- (total of 5, thickness 1.9 mm), ensuring that they are aligned together.

Alignment of friction plates:   Caution The friction plates must be mutually aligned on installation, i.e. the areas with no external toothing -arrows- must always coincide. This is the only way to ensure correct adjustment. If necessary, mark the cylinder to ensure proper alignment on installation.

–  Insert chosen upper shim -4- in input shaft cylinder -A-. –  As a final step, insert the corrugated washer -5-.

–  Press home piston -1- in pressure plate -2-.   Caution l  The inner contact and sealing surfaces -arrow A- of the pressure plate and the piston -arrow C- must not be allowed to make contact with the shaft on removal/installation. l  The contact and sealing surfaces must not exhibit the slightest signs of damage such as scratches or scoring caused by dismantling/assembly. l  In the event of damage, the pressure plate or piston must be renewed.

–  Carefully guide pressure plate -1- with piston -2- downwards over shaft -3-. l  When doing so, the inner contact surfaces of the pressure plate -1- and of the piston -2- must not make contact with the shaft. –  Evenly press home the pressure plate with piston in the input shaft.

Checking clearance with feeler gauge-T40117- –  Insert the two feeler gauges -T40117- underneath the pressure plate -A-. –  Have a second mechanic use the tube -VW 416 B- to press down the pressure plate -A- as far as it will go -arrow 1-. –  Move the two feeler gauges-T40117- back and forth in a circle beneath the pressure plate in direction of -arrow-. l  Apply the two feeler gauges -T40117- on opposite sides. l  Take care to keep the feeler gauges -T40117- straight. l  The entire circular area must be checked. l  The two feeler gauges -T40117- must always move freely without any resistance whatsoever. If the feeler gauges -T40117- cannot be moved in direction of -arrow- without becoming blocked: –  Repeat the input shaft adjustment procedure → Chapter.   Caution It is essential to obtain a successful result when checking the clearance with the feeler gauges -T40117-, as gearbox problems will otherwise be encountered when driving off from a standstill. If the feeler gauges -T40117- move freely in direction of -arrow-: –  Fit input shaft cover → Chapter.

–  Install input shaft → Chapter.

–  Fit oil seal for input shaft -A- → Chapter. –  Fill up with ATF → Chapter „Replenishing ATF for ATF purging“.   Caution t  The ATF required by the multitronic 01J and 0AN gearbox is different to that for multi-step automatic gearboxes. Only the ATF available as a replacement part for the CVT gearbox may be used in the planetary gearbox; ATF specifications → multitronic 01J, front-wheel drive; Rep. Gr.00, → multitronic 0AN, front-wheel drive; Rep. Gr.00. t  After installing gearbox, make sure to perform ATF purging procedure → Chapter „ATF purging“.
