MMT gearbox flashing N

[Dafty]

Hello all, My wife has a 2004 1.0 yaris which has (while driving and static) gone into neutral and started flashing N with the gearbox sign flashing on the dash. If I turn off her car and restart the car then drives fine. This issue has accrued 4 or 5 times in the last few months. Any ideas? I've heard there are 2 actuators, gearbox and clutch which are known to fail but I'm unsure which it would be as no fault codes come up. Any advice would be appreciated. 54k on the clock and otherwise drives and handles really well.

You can do a search for MMT gearbox on this site and you will find plenty of info from the Aygo/Yaris/Auris forums. It is very likely to be the actuator problem with faults inside the separate MMT's ECU. No fault code will come up when this happens. This is a know problem for the Toyota MMT gearboxes which they refuse to admit.
