[Healeys] When to change transmission oil

[Bob Spidell]

The issue in gearboxes is ground metal, mostly brass from the shift levers.  I've changed out oil that sparkled in the 
sunlight from ground brass, but did not feel gritty in the slightest (note some greases are made with finely ground 
metals like molybdenum).

You could probably get away with not changing it ever again--just replenishing what leaks out--but I'd change it at 
10yrs/20K miles because, well, just because.
