What do you think

Thanks

I think your test indicates the hydraulic system in the pump and converter are working for converter clutch lockup. Unless when the trans is fully warmed up , there is a hydraulic failure via an internal leak.

The test results point to the problem you experience is in the area of the solenoid, switches, wires and voltage/power source.
