the "gearshaft fault" came on in my jaguar on 2000 Jaguar S-Type

The term" gearshaft fault" came on in my jaguar tonight and then the orange engine lit up. Can you please tell me what this means and is it serious?

The code stored in the computer after the orange light came on means there is a trouble code(s). Have it pulled up by a qualified shop and then get back on here to give us the code so we can yry to help from there.
