More than likely we have a pressure issue. So we need to start with checking the fluid and servicing it if it is low or not in good condition.

However, I suspect you already did this if you changed the solenoid so if the fluid is correct and it still does not move then we need to check and find out what the pressure is from the pump.
Either we have a converter issue or pump issue but fluid issues can also cause this which is why we need to start there.
Please see the info below from the manual on how to check the pressure and let me know what questions you have. Please look at the last page as well for causes of this and I suspect we are going to have an issue with the No or Low pressure section. Thanks
