Hi all, My wife has a 2010 C4 Grand Picasso 1.6 Hdi Vtr 7 seater. I have forked out a few quid over the last 12 months and recently replaced the clutch for a second time in 9 months (poor job last time around lesson learned) I was advised to convert to a solid clutch and move away from the dual mass one, during the job it was noticed that the gearbox needed to be replaced. Please note I agreed to put a second hand box in. Now the car drives fine and a couple of drop links were replaced too so it all feels well however the issue is that at about 120kph the revs are at about 3200 which feels high, its a 5 speed box and manual but it feels like it needs to go into 6th? Is it possible that he may have put a petrol gearbox in by mistake (is that even possible) The mechanic said the revs were fine just looking for a second opinion if you can please.... |

Could it be a gearbox from a C4 hatch or coupe with a different final drive ratio to the C4GP? | ||||

I don't know whether the ratios varied much between the 1.6 and 2.0 HDi, but all of our 2.0 HDis ran at about 2000rpm at 70mph, so 3000rpm at 120kph (~75mph) seem very low geared. As I have no idea how the car's system works out its speed, I wonder whether the speedo reading is accurate with the new gearbox. |

Just doesn't feel right, 3rd gear feels like 2nd, 4th like 3rd and so on. The revs even sound high in 5th at 120kph. Is there a way I can clarify if the right box is in the car before I challenge the mechanic as I am sure he won't be to keen to rectify the issue at his cost ?? |

Did your car have a 5 speed box before it was changed? | ||||

It would be interesting if someone with a 5 speed 1.6 HDi could post the rpms at, say, 70mph. I don't think I have ever exceeded 3000 rpm on any of the 5 diesel Citroens we have owned, as they are/have been geared at ~ 2000 rpm at 70mph. | ||||

I know it isn't much of a comparison but I'm getting just over 2200 rpm (one notch above the 2000 mark on the dash display) at an indicated 70mph (indicated GPS speed is a bit less) on my C4GP which has the 6-speed EGS box. Hope it helps any. |

Thanks all, back to the mechanic tomorrow, I took the C4GP out for a motorway spin last night and the car was about 3200 rpm on 70mph and the high revs from the engine was quite noticeable. Expecting a lot of deflection from the mechanic but has to be done I suppose. Thanks for the insight |
