Automatic transmission

Hi all,
Just wondering if you can replace the 6 speed auto in a 2008 D3 with an 8 speed auto from a D4 ???

I do not think so...

the electronic parts of the CANBUS in D3 are not matching the D4 electronics and the auto gear box has its own control unit being different to D3.

Mechanical wise I am not sure.

Biggest concern electronics. Achim

I tend to think the same as disco4ever Although, if only the autobox is meant...
CAN is one thing, both gearbox AND engine ECU are involved... So another thing.. Best regards
