Rolls forward in neutral, locks up rolling backwards??

Yes it’s going to have come out and front pump removed to remove that front drum and inspect the clutch teeth. I’m sure they are mangled. When you didn’t snug that front band bolt it dropped down and clutches disengaged.
It’s starting to make sense now that I’m seeing the parts and how they fit together. I’m definitely a visual learner.

Well, at least I don’t have to pull the engine again...yet. And at least there’s not much assembled that I would need to take apart in order to take out the transmission. There’s always a silver lining!
