You can run the NAG1 too, contact Sound German Automotive for the stand alone controller.

I would check the 3-4 accumulator spring after everything else as well. If you have the pan and filter down, you are almost there. 5 bolts I believe hold a small plate under the spring. These springs break and cause shifting problems. They also cause snap ring breakage in the clutch pack drums. If it is broken, you can get the diesel version.
