2003 Ford Windstar it wont go

There are a number of things that can cause this, but we need to start with checking the fluid.

Here are a couple guides that will help with this:

If the fluid is full and in good condition, then we need to do what is called a line pressure test.

This will tell us if there is an issue inside the unit with either the pump or seals not allowing the pressure to build.

I attached this info below. Please run through this testing and let us know what you find, and I am sure we can figure out next steps.

Thanks
