Thanks Mike for coming back to me.By way of clarification:
1)There are no warning lights coming on
2)The juddering/shuddering is most prominent first thing in the morning i.e.today when reversed off my drive.Of course the engine is cold then and there may be some slight improvement when it warms up although it is difficult to say.It also sounds like it is "missing" when stationary in a traffic queue and moving the stick into neutral appeared to lessen this effect.In fairness to the new gearbox however I have not noticed this particular fault for a couple of days since the new gearbox was fitted.The juddering in reverse however remains prominent.
I realise that these faults may be extremely difficult to diagnose and can only ask you to give your best estimate .I am tempted to let sleeping dogs lie unless of course there is a possibility that the car may let me down completely when on a trip(we are hoping to take it to France in August).
Pl.let me know if you need me to clarify anything else.
World Cup prediction: England 0 Italy 0. Japan to reach quarter finals.
Up the Villa
Have a good weekend.
Many thanks Mike,I will refer this back to my garage.Incidentally on sunday morning it was particularly bad and for the first time (again when engine had just started )the car shuddered very badly in reverse and then appeared not to shift itself out of first or second gear when pulling away from standing start.BUT when I switched off and tried it again (going forwards) about 10 minutes later it worked normally! Is this consistent with the possible flywheel situation ?By the way today(monday) it again shuddered badly in reverse but changed gear normally when in drive !
I have left excellent feedback for you.Any additional thoughts re the above would be very much appreciated.
P.S.Hope you did not follow my World Cup predictions.I don't seem to be getting too much right at the moment !
