Hi everyone
First time posting so hopefully I get it right. I have just purchased a 2007 C3 auto for my Daughter but it has gearbox issues.
When you first drive the car after a couple of minutes the gearbox will give a quick bang and changes down a gear (to 3rd) where it remains. A display saying gearbox fault comes on. So if you pull over to the side of the road and turn the engine off and then restart the car everything is back to normal and this keeps happening until the car has warmed up, about 10 to 15 minutes.
Can anyone advise me what the problem may be
Thanks in advance
Nena
