318 LA rebuild after losing a valve seat

Well folks, I've spent the last few days over in the transmission forum reading and picking brains. So far it seems as though I screwed up when I removed the pump by not tightening down the front band. This MAY have caused the band to either come out of alignment or out of adjustment, causing the symptoms I'm experiencing. I don't know yet, because I haven't had a chance to drop the valve body and have a look-see at the band.

So, tomorrow I'll be doing that. I think regardless of how it looks to the naked eye, I'll still readjust it since it's such a simple process. From the videos I've seen and how the service manual describes the process, I can do this with the transmission in the car. Luckily, the drive shaft is out and there's still no fluid in the transmission, so it should be pretty easy.
