The gearbox needs to be replaced in case of serious problems that cannot be eliminated by repairing or replacing its elements. In order to dismantle the automatic gearbox, remove the air intake, disconnect the connectors of the electrical control cables and the starter, drain the transmission fluid, disconnect the automatic gearbox from the internal combustion engine and remove it. To remove the manual transmission, remove the front suspension cross member and front wheel drives, disconnect the speed sensors, and remove the mountings. Installation of new gearboxes is carried out in the reverse order.
