Transmission, Installing

Special tools and workshop equipment required 

• High Temperature Grease. Refer to Parts Information.

• Refer to the "Transmission, Removing" procedure for a list of the special tools needed. Refer to TRANSMISSION, REMOVING .
• Replace the bolts that were tightened with an additional turn.
• Replace the self-locking nuts and bolts as well as gaskets, seals and O-rings.
• Secure all hose connections with hose clamps corresponding to series production. Refer to the Parts Information.

-- If necessary clean and clip in the screen again.

-- Replace the needle bearing -arrow- in the crankshaft. Refer to CRANKSHAFT NEEDLE BEARING, REPLACING .

Tip:

• If this needle bearing in the crankshaft is damaged, the gears are no longer able to shift correctly because the clutch is supported at this bearing.

-- Lightly lubricate the pin and splines on the transmission.

-- 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.

-- Carefully raise the transmission using the Engine and Gearbox Jack and bring it into its installation position with the : 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, re-adjust the transmission support until the engine and transmission align.

-- Attach the transmission to the engine.

-- Tighten the upper bolts -1 and 2- using the : T10179  ; while doing so, note the changed tightening specification.

• The bolt -3- is only accessible via the opening for the removed starter. Use the : T10061  for this bolt.
• The lower bolts -6 and 7- can be tightened with the : T10388  together with the : VAG1331  . At the same time note the changed tightening specification.

-- Remove the : 3282  from the transmission.

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

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

-- Install the new bolts -arrows- of the assembly mounts for the transmission.

-- Check the subframe mount adjustment. Adjust if necessary. Refer to ASSEMBLY MOUNT, ADJUSTING .

• Only remove the : 10-222A  when all assembly mount bolts are tightened to specification and the subframe is installed.

-- Install the starter. Refer to STARTER, REMOVING AND INSTALLING .

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

-- To discharge any static electricity, touch vehicle ground with hand (without wearing a glove).

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

AWD Vehicles
