i have an A 160 mrcedes benz with an automatic gearbox in it, it drives but the problem is it doesnt change gears when you driving. checked the oil level but fine. if you shift to P or reverse there is always a sound coming from the gearbox and it jerks the car too.replaced gearbox from another written off car wich was operating fine but not when it was placed into my car. computer displays "module failure electrical" any solution to this problem?
