Automatic Box Renault Megane Classic

At the moment without problems. I made about 30,000km and has not failed me again. I touch wood.
All the best

What are the symptoms?

One of the symptoms is that it does not have much strength in the first or in the reverse, in despair I changed my exchange box, but we did not change the electrovalve box and it remains almost the same, it improved a little, but it does not convince, it makes the changes at the moment well, in the morning it has more strength than in the rest of the day, when I go on the open road, the witness of the gearbox is turned on, 100,000 of travel, some tell me that the oil box oil does not cool and that is why the box sensor is turned on, others tell me that it is caused by a bad adjustment of the multifunction box is poorly adjusted and that is why a noise comes from there or the ball laminate is evil regulated, the truth is that I do not want to go through that again and I do not know how it is done neither one and the other.

Greetings and thanks

Please someone could tell me if the 2004 Megane automatic boxes are good.

Again with the problem of change. Another two years well and again to loquet with the sayho change. It is desperate.
