hi Guys went to Stephenson really helpful and friendly.
Told me the problem was not gearbox related its a miss fire as it is in every gear when trying to call for more fuel and air to speed up he quoted if i drive like a granny id never know a problem.
so had diagnostics and codes that showed up are p1e30,p3505,p1260( fuel pressure),p09f6(rail pressure) ??? i think maybe be to do with a fuel pump in tank or around it also one of the first codes are boost something???? and glow plugs but i have no problem starting hot or cold always first time .
Any one help thanks guys.
