You have probably received a electrical shock at one time, when touching a metal item. The reason behind this is the electrostatic charge to the human body. This charge can damage the electrical components on the transmission and the selector mechanism.
-- Touch a grounded object, such as, a water pipe or a vehicle hoist, before working on electrical components. Do not touch the connectors directly.
