I have a 2002 Mitsubishi Eclipse Spyder GT v6 that has a diagnostic code P0705. I have replaced the transmission range speed sensor however it did not correct the issue. Could it be a circuit switch, ignition switch or PNP switch. I just spent $100 for the speed sensor switch and dont want to have to keep guessing and buying parts that wont fix the problem. Is there any way to tell what the exact problem is? The car drives however when putting in reverse it shifts very hard and acceleration is not good. Like it is one gear only and not shifting. Please help? :)
