Hey, I've got this problem too. When the TC light on means my TC is not working. My car slide in wet. I took my car to Nissan and they can't find any problem. If anyone know how to fit it, pls let me know.
Also, My R34, since I changed HKS exhaust and trust in-take then I have missed fire especially when pushing hard in 1 & 2 gears. Anyone have any idea of how to fit it?
