I want it to work just fine but in case it doesn't is this a transmission that I can rebuild without any prior experience rebuilding transmissions? I would rather do it myself to save the extra money for a good converter.

In my opinion they are easier than 700R4/4L60E units, Think of it as a TH400 with a few more parts. I have a few tricks to make it easier on you if the time comes.
