How do you fix the reverse gear on a 1993 infinity G20?

To fix the reverse gear on a 1993 Infiniti G20, first, check the Transmission Fluid level and condition, as low or dirty fluid can affect gear engagement. If the fluid is fine, inspect the shift linkage for any misalignments or damage. If the issue persists, consider having the transmission inspected by a professional, as it may require internal repairs or replacement of components like the reverse gear or synchronizers. Always consult the vehicle's service manual for specific guidance and safety precautions.
