My daughters Neon's transmission started acting up one day and when I went out to check it out, it wouldn't shift out of first(4 speed atx) I changed the input and output speed sensors, then decided to change the shift solenoid while I was in there. I also repaired a couple wires that were frayed going to the output speed sensor. I started it back up and it now seems like it is in limp mode....transmission in second gear only. Do I have to calibrate the shift solenoid? Did I screw something up? Any help would be appreciated...
