Peugeot 2008 407 used gearbox

Friends car 2008 model 2.0 hdi diesel automatic 6 speed. The gearbox used in this vehicle is called tiptronic on sahibinden.com. I wonder if this transmission is a different version of the 4-speed AL4 between 2005-2008 before the make-up or it is a different type called AM6. If it is AM6, this transmission is a different variant of aisin production 6-speed fully automatic AF40 (used in insignias). No clear information can be found anywhere, as if it were confidential information.

Hello, sir, there is a lot of information about the gearbox in the link I gave.
