AL4 wont move on 2nd or 3rd gear

I wonder if you've had the same mechanical failure (all be it on a different band - it was first gear mine lost) as my 406 Coupe's AL4?

I'll see if I can find a picture

Found them!

Thank you. To be honest I don't think mine is a brake band fault, since looking at the technical data, brake F1 is responsible for 4th gear, brake F2 is Reverse and brake F3 is 1st and 2nd gears. For me 1st and reverse works so it means both brakes (F2 and F3) are working and Brake F1 doesnt even matter for any other than 4th gear. Although clutch E2 is responsible for 2nd, 3rd and 4th gears, so the problem must be in clutch E2 or an internal leak in that circuit.

If I take AL4 from DS3 with the same engine (1.6 Vti 120) even though the transmission ''type'' is different in the donor car (TS28) but the ratio is same 20x73 and mine is TS67 with same 20x73. It should be ok? Of course I will be using my old TCU.

There is a pretty good chance that it will be compatible.
