57 Hydramatic Shifting


Recommended Posts

My transmission works and shifts good except for quite a harsh shift from 2nd to 3rd.  Anyone else have this situation and if so, what was done to correct it?  Planning to take it to a transmission shop but they are really backed up so who knows when.  They claim to have a couple old timers working that are familiar with these transmissions????  Also, would a flush be recommended or just a fluid change?  I have no idea when this may have been done in the past.  Any insight into this would be appreciated.
