Which is what happened to my TR3 transmission.  But it happened so quickly 
I think there was something caught in the ring causing it to drag and 
overheat. Probably a silicone dingleberry as the PO used a lot of silicone gasket 
sealer on it.  That is what precipitated the transmission rebuild and 
subsequently the frame-off restoration.

I think I need counseling.

But a 4th to 3rd downshift problem wouldn't be a fourth gear synchro but a 
third gear synchro failure.
