Tony and X2 are both correct these gearboxes need attendance to and you will notice that if it is a vehicle that has not had attention paid to its transmission services. Then unfortunately once opened up you will instantly see two magnets in there and you want to pray really hard it hasn’t got to the stage where those two magnets have collected a ****load of micro tiny metal shavings due to negligence. Because then u might be up for a overhaul
