help 2004 s600 Trans Code p0730

I am getting a P0730 Code on my OBD-II Scanner and the car acts like its in limp mode. No forward or reverse gears most of the time and sometimes if I restart it it will work shortly.... Any suggestions?

Thanks!

Any other codes, like wheel speed sensors, were ALL modules scanned

With a capable scanner you can verify speed sensor readings.

As said above, most likely the conductor plate. It sits on top of the valve body, probably something you should take to a dealer unless you're very capable working on cars.
