I bought a TCI 727 for a Mopar project several years ago. It did OK but I wasn't real impressed and converter leaked down excessively if it sat for more than a day.
At the time, it was easier to just order the transmission instead of digging up a buildable core and going thru it. As mentioned in the post above, if your building a project by the time the transmission can be tested there is a good chance the warranty may already be expired. If you do have a problem, even if the trans is still under warranty you will still end up with the shipping and inspection and time hassles associated with having mail ordered something.
Fortunately I have a transmission shop down the road with a very good builder. If I'm not real familiar with the transmission I'll be using I'll research it and spec out any HD parts I want added (like I did on the 46RH I had done for my current project).
