Dill Very interesting reading your thoughts on the Comfortmatic's, I honestly think that a test drive of say 4 to 5 miles is a complete waste of time. I agree on the first and second gear shift when setting off, but this is no different to a manual box in my opinion. It did take time to get used to it, now I drive mine (In Auto) from a standing start to sixth gear without the bobbing backwards and forward in my seat, even the wife sitting in the other seat has noticed how smooth the gear change is. No one has mentioned the Up function when towing, which is a good idea and works a treat. I would definitely buy another.

Pudsey_Bear The main problem with the manual/autos, is if you don't get on with it you're either going to be stuck with it or lose a bundle getting rid of a van you don't want to drive.

Another thing is it'll be main dealer every time it goes awry as your average garage muckyneck wouldn't know what to do with it, and what are used values going to be like too.

But if that's how I would feel why is that nonsense? I've driven well in excess of 100,000 miles in automatic cars and have always regularly used the manual side of the box to change down gear ahead of the auto box in circumstances where I know a lower gear is going to be required and I don't want to wait for the box to engage it and nor do I want to use kick down. I've driven autos with paddle shifts on the steering column, shift levers in the central console and so on. My point was that if I didn't have that element of control then I would not be happy with such a box. Stanner has said I would and I then replied that I was happy with that.

Mrplodd "Proper" automatics are viewed as being the better option for towing these days, I would certainly have one out of choice.

The comments about "not being in control" are frankly nonsense! With automatic the vehicle is always in one gear or another, there is no clutch to wear out and of course. No "dual mass flywheel" either.

An auto actually provides an almost totally variable gearing system so the max torque (when required) is delivered, they are far more relaxing, they are quieter , every single gear change is as smooth as silk, most modern auto's have 7 or 8 gears so mpg doesn't suffer.

Auto boxes EVERY time especially when towing.

The ONLY disadvantage is that the initial cost is considerably higher.

Thanks. That information has removed just about all my concerns.

peribro My vans have been manual as I generally prefer a manual box to an automatic although I have had several automatic cars. In addition I think that a manual box is probably better when towing although that may be an old fashioned view now. However when I do drive an automatic car (which my wife's is and in which I probably drive 8k miles a year) I find a saving grace is that I can switch it into a semi-manual mode and choose what gear I am in. Am I right in thinking that it is impossible to do this with the Comformatic box? In which case I think i would feel that I was not in proper control, particularly when towing.

Stanner It sounds like Renault have it much better sorted than Fiat/Citroen/Peugeot then.

These are not automatic gearboxes in the true meaning of the word.

They are robotised manuals, the electronics do everything from slacking off the throttle, disengaging the clutch (yes they still have one) change into whichever gear it decides is best, letting the clutch up again and matching the revs to the road speed. You cannot actual change gear yourself, only tell the imp that does it all what you WANT it to do, it then does it for you. (At its own pace)

I ran one for a while, you do get used to the slow 1st to 2nd shift, but pulling out onto a busy roundabout can be "interesting" as the bloody thing will always start to change just as that 44 tonnes is bearing down on you and there is NOTHING you can do to speed the process up. There is no "gear lever" only a selector lever that LOOKS like a gear lever.

Andy

Personally, having run one for a few years I would not have another, only a "proper" auto, and that seems to be VERY rare on anything other than those at the very high end of motorhomes pricing.

It might well be, but as the "slow" change from 1st to 2nd is not a situation I have never experienced it's not a question I can answer.
The change from 1st to 2nd can be a bit fierce if you accelerate very hard, so if you ever need to do that it could help to be able to hold 1st for longer.
But even if you do that, the box will still automatically change up to 2nd if you try to over rev it.
It will not allow the engine to go past about 4000rpm or drop below about 1200rpm if a higher or lower gear respectively is available.
