The Allison 1000 transmission that is used with the Duramax is probably one of the best heavy duty transmissions ever made and unmatched in any other brand truck, it was the primary I purchased the Duramax over the Dodge or Ford truck. I have a friend with a 2013 3500HD with about the same mileage as you. He had the same problem you did at about 200k. He replaced the radiator, flushed the trany and replaced both filters and refilled with Transynd and the truck hasn't skipped a beat. Since his mishap he as put on an additional 100k on the truck and this thing tows a skid loaded 3 to 5 days out of a week.
You caught the problem quickly and did the right thing. I think your good to go!
Its sad GM decided to go with there new 10 speed "Branded" Allison in their new trucks, it's really not an Allison since they did not build or engineer it. If Dodge gets the new true Allison 9 speed this will be a game changer for them and I think many will jump brands to get it.
Anyway, Cheers, glad to see your back on the road again!
