Reverse Incorrect Ratio
What it means
P0736 means the transmission computer detected an incorrect gear ratio in reverse — the input-to-output speed relationship doesn't match what's expected. This usually points to slipping, a shift-solenoid problem, or internal wear affecting reverse. Forward gears may be fine, but reverse can slip or engage poorly.
Can I keep driving? Drivable forward, but reverse may slip or engage harshly; have the transmission checked before it worsens.

How to diagnose & fix
Work through it in order
- Scan and confirm the code applies to reverse; note the fluid condition.
- Check transmission fluid level and quality; correct if low or burnt.
- Test the shift and pressure-control solenoids.
- Inspect the valve body; if slipping persists, have the transmission inspected professionally. Clear and re-test.
