Hopity hop Jumpy jumpy

[ChrisGadd]

Help anyone had this happen to them ?

When I pull off in first gear my car sometimes lurches forward sometimes quite violently. It seems even worse in reverse especially when reversing up an incline when I have to give it some revs. These symptoms seem more violent when the engine is hot. All other gears seem quite smooth.

Is it a) The clutch or b) the diff

Have you tried the usual suspects? TP or Coil?? Bizzarre that it only happens in 1st though.

[ChrisGadd]

Thanks for the suggestions Wildfire but it's definitely some sort of cluth transmission problem. The engine feels like it's trying to jump out of the engine bay. Had the engine and gearbox mounts replaced which hasn't made any difference. I don't know much about the diff and clutch but wondered if it's a release bearing or something like that's the cause of the problem. The car has done 72K so is this a sign that the clutch is on it's way out or the diff is worn. Any suggestions welcome.

I had exactly this sympton but only from cold. Cleaned up TP, air flow meters and idle speed control valve and problem disappeared.

[ChrisGadd]

Thanks Ralph but this is not a TP or airflow meter problem. The problem only happens from a standing start in first or reverse where the car quite violently shakes itself until it gets up to speed. Sometinmes it doesn't happen but I think that this is because i feather the clutch it also happens when the engine is cold and hot

Is it whenever the clutch is slipping, or only when you have reversed the torque i.e. from reverse to forwards etc?

[ChrisGadd]

I think it is when the clutch is slipping because it happens a lot in traffic when only mooving forwards

[GreenV8S]

That may mean that one of the clutch fingers has broken. Once one has gone the others are likely to follow, leaving you stranded with no drive. I suggest you get an expert to look at it before this happens. Sorry!

sounds like warped clutch friction plate or broken preasure plate fingers

[ChrisGadd]

Thanks for the advise GreenV8S, sounds like another trip to the local garage but I suppose it’s better to be safe and mobile than risk being stranded.
