If there is a fault in the valve body then the check engine light would come on setting a code. If a solenoid is jammed, most likely it is because some material from the transmission may have gotten into it like worn clutch material or metal shavings. That would be an indicator for a transmission overhaul. A transmission shop can do a stall test hooking up a pressure tester to check for pressure but ultimately a tear down is required to find the point of failure.
Also, you mentioned early you pull a plug to check it? If there is no dipstick, did the fluid come out as a slow drip from the plug? You can also remove the pan to inspect for debris. If full of clutch material or metal, then you will need a tear down.
Also, what color was the fluid?
Fluid condition check:
Observe the color and the odor of the fluid. Under normal circumstances, the color should be dark reddish, not brown or black.
Allow the fluid to drip onto a facial tissue and examine the stain.
If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.
If fluid contamination or transmission failure is confirmed by the sediment in the bottom of the transmission fluid pan, the transmission must be disassembled and completely cleaned.
