Scheme 120
Note. Ignore -1-.
| CAUTION | There is a risk of destroying the transmission control module (Mechatronic) with static discharge. Do not touch contacts in transmission connector with hands. |
Touch the transmission housing (when not wearing gloves) to discharge the static electricity.
Disconnect the connector on transmission by rotating screw connections counterclockwise -arrow-.
Scheme 121
Free up the electrical wiring harness on the transmission.
Remove the bolts -1, 2 and 3- and remove the right drive axle heat shield -A-.
Move the heat shields -B- to the side.

Scheme 122
Insert the T40058 guide pins as follows
Scheme 123
- The large diameter -arrow 1- faces the engine.
- The small diameter -arrow 2- faces the adapter.
To loosen the torque converter bolts, counter hold the crankshaft using the T40058.
Scheme 124
Note. When mounting, turn the crankshaft only in the direction of engine rotation -arrow-.
Remove the 6 torque converter bolts -arrow- by turning the crankshaft 60° in the direction of engine rotation.
Scheme 125
Remove the bolt -arrow- for the ATF line bracket.
Note. Ignore -1 and 2-.
Note. Place a cloth underneath to soak up any escaping ATF.
Remove the bolts -1 and 2- and remove the ATF line -1- from the transmission and secure them at the top.
Scheme 126
Seal any open lines and connections with a clean plug from the VAS 6122.
Equip the VAS 6131 A with the VAS 6131/10, VAS 6131/13 and VAS 6131/14 as follows
Note. The other attachments remain unchanged.
| Platform Coordinates | Parts from the VAS 6131/10, VAS 6131/13 and VAS 6131/14 | |||
|---|---|---|---|---|
| F2 | /13-7 | |||
| B10 | /10-1 | /10-2 | /10-5 | /14 |
| G10 | /10-1 | /10-2 | /10-5 | |
Install the VAS 6131/13-7 at the right front of the engine in the threaded hole as shown in the illustration.
Scheme 127
Install the VAS 6131/13-7 on the scissor lift table and tighten it to 20 Nm.
Remove the starter bolts -1 and 2-.
Press the starter off the transmission and leave it in the installation position.
Remove the remaining bolts -3 through 11- that attach the engine to the transmission.
Note. Ignore -A-.
| CAUTION | Risk of leakage on the ATF oil pan. Do not lay the VAS 6131/14 on the ATF oil pan. |
Scheme 128
