My shift cable is frozen and frozen on the go so I can’t start it. My gear stick is frozen in reverse. As it is running I cannot start it to defrost it. It freezes every time it is below zero. I usually leave it in neutral and start it up and let it run for 15 minutes or so and it defrosts and works fine. I tried using a torpedo heater, but it is too cold outside to make a difference.
Can you check the fluid level? I’ve seen this error before on other units, and most of them are due to low fluid level (probably fully drained).
