My Renault trafic has just started to shudder violently when accelerating from 60mph in 6th uphill low rpm
The whole van shudders
The first time it happened it put me in limp mode.
I can reduce speed and it stops shuddering
The strange thing is it doesn't do it all the time under the same condition
I have had all wheels balanced and
value cleaned when I had the timing belt changed
Any ideas much appreciated
