I have an old Capitol gearbox, After speaking to a mechanic, he tells me that this type of gearbox does not have a damper plate, it is direct coupled.

I am still pulling the gearbox out to check it out, I still have to check out the tappets.

I am still suspicious of the gearbox, but confused as the engine and gearbox ran fine for 2 hours after she released form lockup, I dont know if its a coincidence but she unlocked after i put the gearbox in reverse with the engine off.

The mystery continues
