904 Transmission Stopped Going Into Gear

I did grease the gears in place and slide the pump (without cover) onto the torque converter to ensure that the splines got aligned and centered. I then packed the pump gear cavity with grease before putting the halves together.

I did not use a large adjustable clamp on the pump. I used 2 bolts with the heads cut off as locating pins. I screwed them into the case in holes 180 deg apart, slid the gasket on them, then slid the pump halves on, secured with a few original bolts, then replaced my "locating" bolts and torqued everything to spec.

Of course, Im going to have to take that all apart now, fighting the tight grip on the drum bushing....
