I have an Epica LT 2007 and, at the moment of stopping at a traffic light for example, the gearbox hits and it feels as if the speed got stuck. I was told the failure is in 3 solenoids or sensors that are located in the valve body of the transmission. Is it true? I wold appreciate your help.
Buddy, do a maintainance to the valve body of the transmission. It might not be the solenoids anyway. I recommend you to scan the vehicle to see which failure is indicated, and also check the transmission computer that is on top of the pedals and only takes two screws and two connectores. Remove it and take it to be verified.
You need to replace the radiator with an original one, as if they are generic, they do not cool the same way or even its internal coil does not have the same pressure or flow capacity.
