First I will say that I am not a transmission expert.

I have, however, rebuilt several gearboxes including the Healey rib case in
my Lotus Eleven and one in my BSA B50 motorcycle, and have listened at
length to different gearbox noises.

>From the description of it being gear specific and only under acceleration,
If it only occurred in one gear and ticked or chattered, I would postulate
that you have pitting or chipped teeth on the "drive-side" face of the main
shaft and layshaft teeth for that gear.

I do not know the internals of that specific gearbox, but the fact that it
occurs on 3rd - 5th and it is whirring, I would suggest you have a failing
bearing, probably on the layshaft.

It may last for a long time, or it could spit-out some needle rollers
(assuming it uses needle roller bearings on the layshaft) and have an
immediate failure for those gears.

I am surmising that because it does not occur in the lower gears, it mostly
likely is not a mainshaft bearing. If I am correct and the bearing fails,
you might be able to limp home in the lower gears as long as the rollers do
not land in some inopportune location inside the gearbox. ;-)

For what it is worth... ;-)

Best,

doug
