★ This spring is a crucial component of the T84 synchroniser assembly. The T84 transmission only has synchronisation on 2nd and 3rd gear - 1st gear and reverse are not synchronised. The springs keep the shift plates under constant tension against the synchroniser hub, enabling smooth gear changes. During gearbox overhaul, both springs must be checked and replaced if necessary.
