Transmissão automática de néon da Chrysler 97

Bons amigos dos manuais de mecânica que tais. I need some help with my neon of 97, I am new to mechanics ... The issue is that the automatic transmission of the vehicle is working badly, when the vehicle is cold and I try to go back does not fall the setback and I must accelerate it several times until I fall, I have also noticed that when I am starting the first speed it works well the second takes a little but it falls for the third it takes even more and the revolutions increase greatly. Depois que o veículo está quente, ele funciona totalmente "bem", o revés o agarra

imediatamente, eu rolo pelo menos cerca de 8 km, o que eu poderia saber?

Obrigado, aguardo uma resposta rápida
