CAUTION:

Risk of damaging the transmission by mixing ATF and transmission fluid (MTF) through the same bleeder.

The transmission filled with ATF and (MTF) transmission fluid must be tilted a maximum of 15° in lateral and longitudinal direction.
If more of an incline is needed, then the ATF and (MTF) transmission fluids must be drained. Refer to ATF, DRAINING AND FILLING and TRANSMISSION FLUID, DRAINING AND FILLING .

NOTE:

Replace the bolts that were tightened with an additional turn.

Replace self-locking nuts and bolts, O-rings, sealing rings and seals.

Secure hose connections with hose clamps that correspond to the series production. Refer to the Parts Information.

During installation, all cable ties must be installed at the same location.

There is a normal >>clicking<< in the dual mass flywheel with "LuK" centrifugal pendulum absorber.

CAUTION:

Danger of leaks in the transmission fluid pan.

The :T40173 must not be set on the transmission fluid pan.

-- Mount the transmission onto the :T40173 and secure it using the tensioning strap -1- as shown.

-- The following preparations must be made before connecting the engine and transmission:

All vehicles:

CAUTION:

Vibrations or rattling noises when driving!

Always follow the step sequence, to guarantee that the vibration damper is assembled without tension.
The vibration damper must rest flat on the drive plate when screwing in the first bolt.

-- Turn the crankshaft on the vibration damper 360° in the direction of engine rotation.

-- Remove the :T40170 .
