Procedure 

• Refer to the "Transmission, Removing" procedure for a list of the special tools needed. Refer to TRANSMISSION, REMOVING .
• Replace bolts that were tightened with an additional turn after removing them.
• Replace the self-locking nuts and bolts, gaskets, seals and O-rings after removal.
• Secure all hose connections with hose clamps corresponding to series production. Refer to the Parts Information.
• During installation, all cable ties must be installed at the same location.

Install in the reverse order of removal while noting the following:

• Tightening specifications. Refer to TRANSMISSION TIGHTENING SPECIFICATIONS .

-- Remove the screen -1- of the oil cooler carefully using a screwdriver and check for contamination.

-- Grease the transmission pins (not the splines) lightly.

-- Check if the alignment sleeves -A- for centering the engine/transmission are in the cylinder block and insert them if they are not.

• The missing alignment sleeves due to an offset from the engine and transmission lead to damage to the needle bearing in the crankshaft.

-- Make sure the intermediate plate is seated correctly -arrows-.

-- Carefully lift the transmission using the Engine and Gearbox Jack :VAS 6931  and bring it to its installation position using the Transmission Support :3282  .

-- Insert the transmission without pinching any lines.

• Engine and transmission must be brought together by hand until both flanges contact all around!
• If this is not the case, readjust the transmission support until the engine and transmission align.

-- Attach the transmission to the engine.

• For the bolts -1 and 2-, use the Insert Tool - 18mm :T10179  ; while doing so, note the changed tightening specification.
• For the bolt -3- in the starter hole, use the Socket - Xzn 14 :T10061  .
• For the bolts -6 and 7-, use the Ring Wrench - 16mm :T10388  with the Torque Wrench, 6-50Nm :V.A.G 1331A  ; while doing so, note the changed tightening specification.

-- Remove the Transmission Support :3282  from the transmission.

-- Lift the engine/transmission assembly using the spindles on the Engine Support Bridge :10 - 222 A  .

-- Align the engine/transmission assembly in its installation position. To do so, lift it until the transmission is completely flat on the transmission mount.

• Before installing the bolts -arrows- the transmission and transmission mount must be parallel to each other. If necessary, lift the transmission using the Engine and Gearbox Jack :VAS 6931  .

-- Install the bolts -arrows- but only tighten by hand.

-- Check the subframe mount adjustment. Adjust if necessary. Refer to ASSEMBLY MOUNT, ADJUSTING (DNVB) / ASSEMBLY MOUNT, ADJUSTING (DSFA) / ASSEMBLY MOUNT, ADJUSTING (DXHA) .

• Remove Engine Support Bridge :10-222 A  only when all subframe mount bolts are tightened to the specified torque and the subframe is installed.

-- Install the coolant pipe on the transmission. Refer to [For engine(s) DNVB] OVERVIEW - COOLANT PIPES / [For engine(s) DSFA] OVERVIEW - COOLANT PIPES / [For engine(s) DXHA] OVERVIEW - COOLANT PIPES .

-- Install the coolant hoses on the transmission fluid cooler.

-- Attach the connector for the Dual-Clutch Transmission Mechatronic -J743- and turn the twist lock clockwise to lock it.

-- Connections and routing. Refer to Wiring Diagram.

-- Install the selector lever cable. Refer to SHIFT MECHANISM, REMOVING AND INSTALLING .

-- Adjust the selector lever cable. Refer to SELECTOR LEVER CABLE, CHECKING AND ADJUSTING .

-- If the transmission is replaced or the bleeder line is removed from the transmission: remove the closure cap -arrow-.
