The D light is blinking, the car does not have strength and it consumes an unusual amount of petrol.

The blinking light means there is at least one code stored for the transmission system. That would cause both issues. However you would need to use a scan tool to read the code(s). Then use the code(s) as a guide to discover the actual problem. It could be as simple as a sensor on the transmission or as bad as internal parts failure. Honda didn't include a way to read the codes without a tool though, there are some inexpensive code readers available these days but you need to be sure they work with Honda.
