@GemeineWurstI have the same TM TX Base and the same Ferrari wheel as well as the new SF1000. My TM TX base is more than 5 years old and I never had that issue with downshifting on it's own....never. I would have noticed it right away if I did! Try another steering wheel if you have one available or it might be something else that is causing it to downshift on it's own other than the wheel..
