Hello everyone,
In France, we do not have the culture of automatic gearboxes.
It's very hard to find a professional to fix them, and when you find one, he asks for the price of the car.
Many do not know how to get back an American gearbox, and it happens that we get the car on one side and the parts on the


other ...


My problem is the 3 and 4 skate.
If I roll slowly, all gears pass, but if I press a little on the accelerator or if I climb a slope, or too much weight, 3 and 4 skate.
The speeds go down well,the level is good, the color starts to turn slightly brown, and a smell starts to feel, but not too much.
There were no precedents before this problem, it came at once, I entered a highway, I downgraded from 4 to 3, and it skates


since.
I had to do 15 km since this problem.
Arrived in town, I put the second (forced), and more skating problem.


The mechanics I know can not tell me if I have a mechanical problem, or if it is an electrical part to change.
The problem exists both cold and hot.
I have an appointment to change the oil and the filter, and put a special fluid before, to clean the box (I believe in luck


??)
In France, many American cars end up in the trash because of gearbox problems (except for more expensive cars).


I see the last post on the same car as me and has a gearbox problem, and ... nobody answered ... it scares me a lot, because


when you have in France, an American car and do not have too much money, we feel very lonely ...
(help me obi wan kenobi you're my only hope )


Thank you for this future help
