Procedure 

Fig 4: Transmission Maximum Tilt
GWWA34-11304Courtesy of AUDI OF AMERICA, LLC
CAUTION:

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

  • A transmission filled with ATF and MTF transmission fluid must not be tilted beyond a maximum of 15° in a lateral and or a 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 Refer to 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.
