Like you I scored one, but 25 years ago. At that time the average trans guy didn't know what could be done with it, and I traded it away for a TH400 core that I had built. I was using mine in a C10 I was building.
It is basically a HD version of a TH400, and lots of things can be done with them. Just besure to get rid of the TH475 converter which has no choices for performance. If that is your angle.

GM had a true HD unit.....The Allison AT545 & was used in many GM Medium Duty trucks, Ford also used the AT545.
Motorhome 3500/350/30 chassis are considered Light Duty.
