Hi
While driving the box changes fine until i get in forth gear.
when i try to put my foot down slightly there is a very bad
vibration from under my feet area,
If i kick down it goes away.
In sports its ok as the rev's stay higher.

Its like if your driving a manual and try to accelerate from
10mph in top gear.
Two day's ago i had the left hand CV explode and i thought
that may have been the problem but no.

Thank you.
