Got the truck back today after the rebuild. No more grinding sounds when in neutral and it goes into all of the gears crisp and firm. Unfortunately, some eh-hole broke into it and ripped out the ECM (along with my tuning equipment), stereo, and wideband O2 gauge. I found a replacement ECM at a pick-a-part yard to get it running, but I'll need to order some stuff to get a new chip in it and running right so I can do a good road test. Total cost on the rebuild was about $2150, but they knocked some of that down to help replace the stolen parts.
