check the oil first (gearbox) or get a dealer to
Mick,
I have an almost identical problem with a 406. Happened a couple of times on Sunday and was fine when restarted. I've had it in to Peugeot cos it was going in for service anyway and, surprise surprise, they can find nothing wrong. But, they can find nothing right! No communication from the engine ECU to the gearbox ECU. And such is the quality of peugeot techies that if the laptop doesn't give them the answer, they're stumped. Basically the gearbox and ecu are functioning fine but may not forever. I have the part number from peaugeot for a replacement gearbox ECU (£650 +vat) and they want me to order it to see if that's the problem. OK then... They did say that pettern ECUs exist, but I can't find them. Does anybody know where I could get a recon ECU for a gearbox? Please keep me updated on your problem, as we speak my car is running fine.

Your best bet is a breaker's yard or send your ECU to an independent specialist to see if it is faulty. Personally I doubt the ECU is at fault. It seems too often engineers blame everything on a faulty ECU.
Garages don't like spending much time trying to figure out faults like this because they know they can only charge so much. They make far more just doing bread and butter stamped servicing.
