Sorry to hear about all the issues.
Still didn't see or read WHERE the trans fluid was leaking from.
Also, did the fan clutch lock up like it is slowed to before overheating? You can hear it lock up and roar when temps start climbing.
How do they know you need a new radiator? Trans oil in coolant? Leaking one or the other fluid?
Sucks to be in your shoes and wish I could help more. Maybe someone on here near you is knowledgable on Fords/diesels/ vehicles in general that could get in detail to help you figure it out.
Hope the shop takes good care of you. I'm paranoid of shops and can do my own work so easier to sniff out the bs.
Good luck.
