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.
