"They pulled it all apart and approached it as - replace anything necessary. They told me that most everything inside the trans looked like new, including an aftermarket HD torque-converter that someone previously installed."

From the way the transmission was working OK until the front seal went bad it sounds like you had a less that stellar transmission shop do the work of replacing the pump and oil seal. They undoubtedly caused the next failure that you are now experiencing. If it is failing within 1500 miles of leaving that shop it appears that they may have installed something incorrectly and it is now generating metal debris which is playing havoc with the shift scheduling. They probably made a small problem into a big one.

Since you have indicated that there are wear particles in the transmission pan that weren't there during the London teardown it looks like you have to find a good transmission shop with a known reputation for good work. The challenge now is to get all the debris out of the entire system including the cooler circuit for the new rebuild.

Those pesky thrust washers have a tendency to get out of position during component installation. They then wear off and cause metal debris which jams up everything.

The solenoid pack is succeptable to the very small ferrous particles which feel like talcum powder. They tend to get into the magnetic field of the solenoids and pack in behind the armatures of those valves.

By the way this transmission uses Mercon not Mercon V oil.
