Excursion overheats&leaks tranny fl towing going 50,uphill

Thank you all for the posts and advice--and link to the diesel site. We are getting a new radiator today. Will either be on our way--after 9 days, because we should have gone to a diesel shop tomatoey, others could have done it but they just don't see these ptoblems and are apparently afraid of these older diesel vehicles, they don't see a lot of our issues--or limp back home and go back to our lives for a bit as we get it worked on locally.
