G27 H shifter Problem

[Polete]

Well some weeks ago I've started having a problem with my g27 shifter. When I put 1st gear it works fine, then I go for 2nd and sometimes when I have already put it, it automatically changes to 4 and then back to 2nd, normally it does that one or two times pretty fast like it is not gearing fine or doesn't know if I am putting 2nd or 4th. also having the same problem when putting Reverse, it changes to 5th/6th, depending on the car I am driving, and I have to take off 5th/6th and put reverse once again, and sometimes work.

Any idea of what is happening with my wheel? I got it for about 3 years now.

Hope you guys can help me, if somebody had the same problem and fixed it out, hope he can post it below and I will try it.

Thanks in advance
