Automatic Gearbox Manufacturer

[MikeRotherham]

Hello,

 

I wonder if anyone could tell me who manufactures the conventional 6 speed automatic gearbox that is fitted to the diesel C4's. I'd like to find some information about it.

 

Alternatively some experienced auto driver may know.

I'd like to know if when sat in stop start traffic. It causes more wear on the gearbox to put it into neutral and back again to D(rive) repeatedly using the handbrake as required or sit with your foot on the footbrake left in D(rive) and as a consequence dazzle the driver behind with brake lights.

The gearbox is a manual box with a manual clutch......the bit it does automatically is to operate the clutch as required and to change the gears as required.

 

Knocking the box from drive to neutral should have no effect on the wear characteristics of the box or clutch......and should you apply the handbrake whist in gear, and subsequently pull away.....if the handbrake is set correctly it will release automatically....but you probably know that.

Isn't that the EGS you are describing? The Automatic is a proper auto isn't it?

Hello kfk,

 

Rereading my post I don't think I explained very well. I meant a 6 speed conventional automatic with torque convertor and not the EGS type.

 

I've read conflicting views about moving from Drive to neutral and back again in stop start traffic. I read that its best just to leave it in drive and hold it on the foot brake otherwise the car creeps forward as autoboxes do.

I suppose basically i want do what's best for the gearbox. This is my first car with a gearbox of this type. I've had a C3 with a Sensodrive which I liked a lot. Would have liked a C4 with EGS but there's nothing around here at the moment.

Driven my mums last 3 cars which had conventional autos in them. I just used to put the handbrake on like normal and put it into neutral. Never caused a problem with any of the last 3 cars I have driven with autos.

Well spotted glad your awake ....... The fully auto box has no clutch to wear out and leaving in gear whilst stationary isnt going to be detremental

The lazy way is sit there with your foot on the brake, with the 'box in Drive, ensuring the car doesn't creep forward. And yes, the brake lights will be on.

 

The preferred way is pull on the hand brake and push the lever to "N".

 

There's no clutch to worry about, and moving between N and D every few seconds is nothing to worry about, though with some cars moving into D can cause the car to move forward, sometimes with a bit of a jerk - but modern boxes are generally very good.

I agree that putting it in neutral is best. I did read on the ROSPA website concerning automatic gearboxes that doing that caused more wear than sitting with the foot on the footbrake. But neutral is the way to go.

 

Thanks for all your replies.
