I have had a terrible time with my transmission. I ordered a Stage II for a motor dynoing 403 at the rear wheels. I has lost reverse twice and had to be rebuilt, in a total of less than 5K miles. Further, Amy's responses lacked any customer focus.

Mine lasted 45k miles, then lost the OD direct clutches while towing back to Seattle from Montana. Contacted Jeff, advised to adjust kick down and replace electrical components. Had the Stage 2. That didn’t work obviously. Went with a local builder, that lasted 10k. Rebuilt again under warranty, I asked for the full Monty on the clutches. That’s been ok for the last 7k. Funny thing is the OEM one that is supposed to be a giant pos lasted 98k.
