I just googled it for you.

The main reason the car won't go into gear is that the level of car transmission fluid in the vehicle is lower or higher than the required limit. If the level is low despite regular maintenance, there may be a leak. Whereas, excessive transmission fluid may result in trouble shifting gears and gear slippage.

Prob something different but it's a start.

That sounds like a diagnosis for an auto box. My money is on the clutch
