hello again I have just tried to drive my range rover td6 auto, I have had the car for a while with no major faults, I pulled away from a junction just now and as the range rover went to change up into a higher gear it started to clunk and vibrate really badly so I stopped dead of my own accord I then put it in reverse no problem no noise etc, put it back into drive pulled off fine again no noise on change up same again now sat waiting for rac to come save me
