Hi

I have a 2003 307 Wagon.

I bought it about 15 months ago as a 'demo' model -with only 8000 km on the
clock.  Soon after getting it, it kept producing the 'Automatic Gear Fault'
display, and it  obviously had a problem - it would hesitate/shudder around
55/65 kmph as though the auto transmission couldn't decide which gear to
engage.

The transmission was replaced under warranty - the diagnosis had something
to do with the 'torque detector' (I think that was the name given to the
problem!)

However, just recently, several times the 'Automatic Gear Fault' warning has
again  been displayed - this time after decelerating or accelerating at slow
speeds - sometimes with an audible 'clunk' or shudder.

I am due for a 40000 Km service in a week or so, but would like to have some
idea of what is likely to be the cause. It is now just over 12 months since
the first transmission/gearbox was replaced. Would this be under a separate
warranty from the car warranty which has now expired, and is it likely that
any repair/replacement would be free of charge?

Hi Tor,

I have similar problem as you describe. Since this problem trouble me a lot,
I asked my dealer to solve the problem. The dealear asked me to change my ECU
of the transmission. It is very expence. So I search in Internet. Someone
help me by doing following steps and it works.

Step1: Disconnect the negative wire from your car battery.
Sep2: Disconnect the wires in ECU of transmission.
Step3: Wait for 5 minutes
Step4: Connect the wires back to their postion.
Step5: Connect the negative wire back to your car battery
