1 Answer


There are many factors that would cause such problem, however, to highlight the most common reasons: 1- Bad shifting cable (replace cable) 2- Shifting cable mounting bracket loose (adjust and tighten shifting cable bracket. 3- Internal shifting rod out of place or broken (need transmission work, worst case) If the car starts in Part and Neutral and not in any other position. reason number 3 is the most possible. Best of luck.
