You have probably received a electrical shock at one time, when touching a metal item. The reason for this is the electrostatic charge that is built up in the human body. This charge can lead to malfunctions when contacting the electrical components of the transmission and the gear selector.
-- Touch a grounded object, for example, a water pipe or hoist, before working on electrical components! Do not make direct contact with electrical connector contacts.
