MECHATRONIC, Removing And Installing: Installing
Install in the reverse order of removal while noting the following:
Risk of damaging the ATF pump.
- The pump for the Transmission Fluid Auxiliary Hydraulic Pump -V552- can start up on a non-deactivated control module immediately after installing the connector.
- The pump can be damaged, by this or the residual oil can flow out under high pressure.
- To prevent this install the transmission control module connector after installing the oil pan and the transmission filled with ATF.
- Only install clean parts: remove the new mechatronic from the packaging immediately prior to installation.
-- Replace the seals -1, 2, 3 and 4-.
Tip:
- The seal -1- is only for vehicles with a Parking Lock Solenoid -N486-.
The Oil Sump Assembly Pin: T40199 prevent the Mechatronic from tilting when it is being installed.
-- Replace the Mechatronic evenly and install the bolts -6 and 7- hand-tight.
-- Remove the Oil Sump Assembly Pin: T40199 .
-- Install the remaining bolts according to the tightening sequence. Refer to Figure.

-- Tighten the ATF drain plug.
-- Fill 3.5 liters of AFT in the transmission using the Pressurized Gearbox Oil Filler Kit: VAS 6617 . Refer to ATF, DRAINING AND FILLING .
Tip:
- The ATF level can be adjusted after operating the control module.
- For the following components after replacing a set up must be performed:
- Transmission Control Module -J217-
- Valve Body --
