Hi everyone,

I’ve got that fault code and my car will not engage in any gear after 3rd. It’s been hard shifting for a while and slipping in 4th but it’s now gone completely. I really don’t want to have to pay for a new transmission so I’m wondering if there are any other things I can try first and how I do them. I’ve been told there is something you can in VCD’S to fix it but I can’t find anything info that. I have VCD’S so if again, if anyone knows anything please get back to me.

I’m in your hands ladies and gents!

Very kind thanks in advance
