AHHHH !!!!
Ho Ho Ho
I've been looking for a post about that! I was sure someone stuck something between the shifter and the car.
Did it help ?
Yes - Remove all the crap from car's tray areas - coins/sunglasses/CD
And where did ya get the matting from ?
Old rubber car mat
Is it easy to put the matting in ?
Remove shifter and insert and refit shifter
Do I have any more questions ?
LMK
I think the violent vibrations might be to do with the clutch slipping ... guess I do need a new one
See if the above help
All the best
