Hey guys, this is a bit of a cross post with the main drivetrain forum, but more specific. My rebuilt 6L80 is failing again and I'm considering a swap to something else. Maybe even just a TH400 as this is not a daily driven car. I know Circle-D specializes in these 6L80s and similar, not sure if they work on TH400s or do any really custom work, but I'll call them in the AM to find out.
What are some other shops that are reputable for taking on a TH400 or similar swap? The TH400 seems to fit well, and it doesn't seem particularly difficult based on some posts from users that did it. One user claimed it's a one day job if you have all the parts lined up.
