Default 04 Lancer ES Speed Sensor Malfunction

My car went into "failsafe" mode and engine light came on. Took it to a mechanic and it was speed sensor malfunction, he replaced one and drove it around and it did the same thing. He replaced the other one and still did the same thing. Now he looked at electrical system and seemed fine, can't find the issue. Suggested to replace the instrument panel because speedometer would fluctuate from time to time. I don't know if replacing the instrument panel will help it shift the car, what do you guys think? It just seems like something is shorting the sensors everytime he replaces them. Please help! I'm currently stationed in Germany and it's hard to find a mechanic who's knowledgeable in japanese cars. Would replacing the TCM possibly fix this?
