It was "rebuilt" before I got it by someone who did lots of fun things wrong. For example, a bushing in backward that heavily restricted flow. Other stuff, too, that's why it failed. I rebuilt it. Just me, a willingness to try and a bit of "book learnin'." Right out there in the driveway. I reused most parts if they looked good and specced out. I kept all tolerances as tight as possible. That means it doesn't rattle uncontrollably. Shifts like a witch. No idea what brand most parts may be. Running type F. Works. I was just concerned about the conflicting info. I haven't touched an automatic since the early 70's. That was a powerglide. Some folks object to calling those transmissions, but I kinda like them for what I did with them. I learned about using safety wire when a bell housing bolt backed out and contacted the flex plate. That'll make a believer outta you.
