I had everything done, the Celunoid, the transmission flush, and filter changed, and the two sensors, input and output changed. It totaled $949 because I told it to a dealership, stupid on my part. But the place that I bought it from actually paid half, which I was greatful for. The guy I bought it from called the dealership up and talked with them and the mechanic said that it was necessary to have everything done, so I dont' think they screwed me, just on the price. But everything is running good, so I'm greatful.
