Sounds like Its just horrible timing. The shop shouldnt have touched your tranny, as far as them saying "its normal" well as you can see they were ass wrong.
Hows the fluid look? Do you know the actual cause of the tranny going out?

have no idea but it is getting rebuilt as we speak to handle uo to 550hp, so this should do the trick for a while? hopefully!!
