I've only just spotted this thread and haven't had time to read all posts.
Pump not running when driver's door is opened is sure sign pump is broke or it is not getting any volts. You seem to have proven pump is OK. So control circuitry is most probable cause.
When this happened to my GTA. It was still under warranty and I was near a dealer who knew Selespeeds and diagnosed it as duff pump in minutes.
I doubt of this can be a gearbox or clutch issue. It must be electrical fault.
Selespeed system can misbehave if battery is on way out. How old is your battery?
