Jeep Grand Cherokee Laredo 2002

Hello friends, this vehicle came to the workshop and presents the following intermittent failure.

When placing the automatic changes selecting lever in D the square is turned on on the letter that accuses the selected change and is normal.

But there are occasions where the same square surrounding the selected change is lit simultaneously in the other changes, p, r, n, D. each letter of the panel is surrounded by the square indicator of the selection.

When this happens. The vehicle does not respond, it does not move in any direction and what is worse when the vehicle is already in indifferent motion of the speed, there are times that also does. causing the vehicle to be without traction and also if normality is resumed causes strong pulls in the vehicle.

When scanning does not yield fault errors, and we believe it can be the fault of the selector lever.

Someone has had a similar problem that can guide me.
