MMT Semi-Automatic Gearbox problem on 2006 Yaris 1.0 Sol

[davidv]

Hi everybody.
Just signed up to YarisWorld today. I have a 2006 Yaris 1.0 Sol with the Semi-Automatic (MMT) Gearbox and would like some information/help/advice
from anyone experiencing the same problem.

Last summer, the auto started going into Neutral (N) while stopped at lights
or road junctions/tolls etc and would stick there. The only way to get back into 1st gear is to switch off the ignition, wait a minute or so, then switch on again.
The car would then drive OK until next stop at lights/junction/tolls.

I have taken the car to Toyota dealers in Greece and Italy and both times
a mechanic connected some kind of computer/PDA to a socket under the
dash and said he was going to "Reset" the onboard computer!

What's the deal here? Can this problem be fixed once-and-for-all?
