Hi, i have a 2002 Neon wich is my DD and recently is giving me some problems, it get stucked in 1st gear, i already changed the output speed sensor but still the same.
What else do i need to check?
Is an automatic trans. Fluid is clean, speedometer gets all crazy, gasoline gauge drops when i push the gas pedal.

 

If it's stuck in a gear (usually 2nd for limp-in mode), there's probably codes? What are they?
