Form in Automatic Fiesta 98

Very good, I have a problem with the behavior of an automatic gearbox of a 1998 Ford Festival Quartz 1.25. The fact is that when I engrano a march (whether direct or reverse), it gives a very abrupt pull and there are times that the engine is even covered. Another problem is that from time to time there is no way to stop it, you almost have to climb on the pedal or but put the lever in position n, it is as if I would not find out what I want to stop and the box continues to send power to the wheels. I await some opinion. Thank you so much.

It sounds like a problem with the valve box, how long did you do the tuning to the speed box?

The truth is that I think that valve adjustment has never been made to the box, do you know if it is very complicated? Is there any manual about how to do it? As you see I am not very familiar with automatic boxes. Thank you.

Actually the box has no valve adjustment and you don't even think about opening it because it is very difficult to repair if you have no experience it is best to take it to a workshop that is dedicated to automatic boxes, what you can do if you want is to take it out and take it to save you some pesos.
