Autozone aand OReilly usually have very capable scanners by Bosch.
You are towing pretty heavy and your trans is slipping, meaning the steels and clutches are wearing out. The more this happens, the more often it will become, until you need to rebuild the trans. Kep the throttle pressure light at shift points, let next gear engage before applying more engine power. There are kits that will increase the line pressure to help the clutch packs hold, but once they start to slip on a regular basis, I don't think they help much.
