I'd just be easy on it for at least a couple hundred miles. I heard of someone else getting their 4l60e rebuilt and they just didn't really beat on it for the first 500 miles or so to be safe.
When I got my crate motor, I just went easy on it for a few hundred miles and it's been fine since. I'd guess the procedure is kind of the same for trannies.
