Hello forum,

Since 3 months i have huge problems with my car.
A peugeot 307 sw year 2005 1.6 16V gasoline engine, AL4 automatictransmission.

Sometimes i can drive normal nothing happens all is fine.
But sometime the wont start, i have no gear displayed in the display, the lock up switch for the gear lever doesnt open. So i cannot shift to D or R or whatever. With force i can pull the transmission lever to D and can drive without shifting. It feels like a emergency mode or so. I came home and that the importend point. But this is no option for everyday.

2 weeks ago i change the ECU(bought a used one from ebay) for the AL4 transmission. The problem was vanished for 2 weeks. But i drive not so much the last weeks, maybe the problems was not completly solved.

I checked with my diag interface and pp2000 all the valves and parameters at the transmission. I cannot find and issue with these. Something is wrong maybe the ECU from the transmission was not the problem. I think the main ECU(BSI) is making the trouble. Can someone tells me about this problem or has tip what can i check next.
