GM built the TH475 to compete in the HD truck market. Where as the brand F C6 was strong enough from the factory.

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.
