I'll be doing some more troubleshooting over the course of the summer. Looking at all connectors, polishing all contacts, inspecting the TCM and reworking as necessary, etc. I also am going to drop the valve body inside the transmission itself and will replace the filter. We'll see how it goes.
I replaced the solenoid assembly at the beginning of NM's fall last year. Worked for a while but didn't solve it. There is a TSB out there stating to solder the ground wire. Crimp itself on the ground wires might be disconnecting in the fluid. Who knows. Can't hurt to do it.
