My 1993 VX HDJ81 does not want to down shift from 3rd gear to 2nd or 2nd to 1st unless I am at almost a complete stop. I am fearful that it is the synchros. I have tried double clutching and old school revs to speed with no luck. I plan on bleeding the clutch in the hopes that may solve it. Also thinking about the transmission fluid as well. I have zero issues shifting up. Any thoughts or insight is greatly appreciated.
