Automatic transmission Renaul Megane 2003 16 Valves 2.0

Good afternoon.

I have a 2003 Renault Megane Auto 16 Valves 2.0 liters with F4R engine.
And the automatic transmission sensor is being activated.

The car moves, but in panel the leta d continues to flash and the failure alarm in automatic transmission is turned on.

I no longer want to move it for reasons that are completely damaged by the transmission

someone can suggest me that it can be what is happening to the car.
And what do I have to check.

I greet your friend

The fault light in the picture may be due to three things.

1º that has under the level of ATF oil. In which case the only thing to do is replace it.
2º That some sensor is giving problems.
3º That some valve in the change mechanisms of change is stuck and not between or does not come out the speeds.

If the light does not turn on due to lack of oil, it is best to take it to the workshop and it would even better be that Renault itself because it can be a fairly expensive breakdown, because automatic changes are quite complex and delicate to disassemble.

I hope I have helped you even if they are bad news.
All the best.
