I bought a used TT transmission a few years ago to get rid of my 4th gear grind. It was going in my NA->TT swap with NA diff. The sensor in the used TT transmission was cleaner than my old sensor so I swapped gears on the sensors. It looked the same IIRC. If I'm wrong, my bad. But in my case they were functionally interchangeable and has been working perfectly for 6 years.
