Let me say this, Jeff. Taking it to a shop is not being a quitter. In fact, for as little as you will ever be rebuilding transmissions, it makes perfectly good sense to turn it over to professionals. It was a great (though seems bad) experience, and you have more knowledge now than ever about transmissions. If you decide to pull it and try it one more time, great. If you take it to the shop, great. I applaud you for your efforts either way.
