It wouldn't hurt to ask the mechanics what they noticed. I don't see how they could wreck the tranny though. They wouldn't of even touched it. Maybe they had fun on the test drive though and that was enough to trigger past deficiencies.
There's no denying 62TE is a POS tranny all in all. Some have had good luck but many have had bad. I would extract and replace 4 litres 2 times and see if it helps.
Maybe back when the transmission shop looked at it they put in universal fluid instead of atf4?
