I put that query to Google 'AI' and got at least one suggestion that 
isn't likely: synchronizers. This isn't likely because synchros are only 
in action when you engage the gear, and the usual symptom is hard 
shifting. So, I'll throw my semi-educated guess in (Disclaimer: I've 
only rebuilt a couple transmissions, both std/manual).

First, though, some questions: /Why did she take the car to a shop in 
the first place?/ For the 'whirring noise?' Did the noise just start, 
she just noticed it or was it noisy after she got it back from the shop, 
but not before? Was it there after she got it back, but it was tolerable 
and got worse over a year? I don't know what a shop could do to cause a 
gearbox to /start /making noise that wouldn't cause serious damage. 
Maybe put bad/wrong fluid in or, a deliberate act of sabotage like 
putting some kind of abrasive in the box.

Knowing these would help a bit, but my guess is bearing/s, either 
input/output or layshaft (though I wouldn't expect that on a maintained 
box before at least 100K miles). A good/honest shop would stand by their 
work, if they did anything, and the best ones would rebuild the box, and 
not just throw a junkyard box in there; getting the box out/in is the 
hardest work, going through a manual on the bench is /almost/ fun. If 
you're able, I'd try a fluid change and put one of the better synthetic 
fluids; Redline and others make some good ones.

My most recent experience with a transmission was with my '96 Ranger 
(3-spd auto with overdrive and 134K miles). Started not shifting, 
holding a gear, etc. so I took it to a local shop, who didn't say off 
the bat I needed a transmission, but did some diagnosis (then they told 
me). It needed a complete rebuild, which cost me $3,500 but the truck's 
worth it, and they showed me the worn/replaced parts. They insist I 
bring it back in in a year for service to keep the warranty, which seems 
reasonable (there will likely be some clutch wear-in and a new filter 
and fluid would be in order). They also told me the Rangers used the 
same gearbox as Pintos, which chafed my hide a little (thanks, Ford ;).

Kudos to the lady for 'driving a stick.'
