Semi auto gearbox problem

[Bigred247]

Hi,

I have a Toyota Aygo 1L petrol semi auto and am experiencing an issue with my gearbox. As I drive the car along the road it frequently switches from regular drive mode 'E' to N (neutral) by itself and brings the car to halt. This is causing me all sorts of issues and only after switching the ignition off and removing the keys for about 20 seconds does it sometimes fix the problem. However, it is now becoming unbearable and too frequent. This has been going on for a few months so I don't think it's the actual gearbox but feel it is related to a software glitch or something? Has anybody else had a similar problem?'can you please advise a fix?

how old is the Aygo? This is a fault that has occurred with older models.

From these threads its probably an actuator problem. I've had MMTs before but never had them long enough to become a problem.

This is a very very common issue when the actuator wears out, be it on Aygo and Yaris.

It is going to cost you if you want to replace it.

I am having this issue currently, did you ever find a solution, we replaced the clutch hoping it was that but with no luck

Only Toyota dealer can eventually help. Best to trade it in for another car and stay away from mmt ( automated manual transmission or dsg) . These are nothing but trouble. Toyota hybrids has the best automatic transmission from all cars in the world, get one of these or cvt Toyota Aygo 2022->
