hello friends 407 2.0 executive premium auto lpg 173bin km it has been giving prnd malfunction in my car. There had been a coil failure before, then this failure came out, the coil was made but prnd does not go from the screen. There is no problem in gear shifts, there is no problem in tiptronic use, there is no mechanical problem, such as knock-in. In the industry, I connected to the computer, the transmission error does not appear. What could be the problem? In your opinion, a part called the electro valve has changed at 120 thousand km. Is there a master that you can recommend electronic or software related?
