EGS, EGT and other robotised manual gearboxes.

In the long run are those cheaper to maintain than " true " automatic gearboxes?

The problem is that you wont get a true auto box on a modern car, less it is a 4x4 or a big luxury model.
The robot changers are not bomb proof, in fact all can be problematic at various mileages. That goes for French and German. Honda i shift was the best of them all on reliability.

What about eat6 aisin gearbox. Isn t it a proper auto box?
I want to buy a diesel cactus but I have heard horror stories about sensodrive gearboxes. Correct me if I am wrong but in my opinion the robotised gearbox is going to cost a lot more to keep operational. The proper auto box does not have dmf, clutch and actuators. Yes, it is not as fuel efficient but what is the point of having a diesel if the gearbox eats all the savings in the long run. I am planning to keep the car for a long time and the mileage is going to be about 250000 miles in the end.

I had a c2 sensodrive which stopped working. It refused to start. I tried all the bsi resets etc and a new battery and nothing. It had less than 100k on it and the most comprehensive service history by main dealer then indy specialist I have ever seen. It cost over £1100 to repair. I lost interest in it and sold it at a huge loss to myself. I then saw it for sale as spares and repairs about a year later as a non runner with a quote from the same citroen dealer that I used for well over a grand to fix it. I will never have another semi auto, sensodrive, egs, dsg, or whatever else they call them.

You serious? The proper auto box actually does have all the things you've listed (sadly), to have the best driving experience possible ... AT6 (Aisin Warner, 6-speed full automatic) i.e., and a fair number of other similar gearboxes all work on the same or similar principle, and those things will give out ... you'll be lucky if you manage to reach 200000 kms without servicing at least one item from the list (unless you're driving 1000 km daily, without shifting - highway or other long, open roads)

[lexi]

Yes. the EAT 6 is a proper Epicyclic box. This is new tech so no reliability record yet. This could be the move back to proper auto. Many other Nissan/Renault have the Jatco CVT Box. Again, mixed review. I have had a bundle of proper auto boxes, going back to Hondamatic models. Haven't had a failure . If you get the new EAT 6, just make sure you can get the fluid out of it for a change at 40k.
The proper auto box has no clutch dmf etc as you state. Clutches on proper auto are a totally different thing to DMF and dry clutch. No clumsy actuators either. Proper auto box is a work of art in comparison to manual box DMF and actuators. It is also a lot stronger and capable of taking more power.

[vborovic]

We're talking about the auto box vs. the robotized variants in the topic title, or fine details among the proper auto boxes? Because if it is the first cone, you can't have what doesn't exits, i.e., you can have a C5 X7 with the robotized or AT6, nothing else is available ... if you want' to buy a "proper" auto box, you'll probably want to stay away from the newest PSA cars, they won't have them

[Raul]

Peugeot 2008 has an EAT6 option. Unfortunately the cactus does not have this option, still. It seems that I simply have to wait. I would go for the etg6 but the stories about software problems, actuators failing( costs thousands to replace), possible dmf failures and normal clutch wear/replacement makes me think about the point of having an eco diesel with a mony pit gearbox. I could live with the jerky gear change etc, but the point of the diesel to me is saving money. On paper the etg gives very good economy, is very light etc, but in real life it seems a 3 litre pertol with conventional automatic gearbox could end up being cheaper to maintain in the long run.

Not far from the truth actually ... usually people just compare the petrol/diesel prices and consumption and calculate the rough estimate of yearly savings ... without taking into consideration the maintenance costs of one against the other

We've been here before

There's a thread about the EAT6 box - it's a manual 6 speed box with the clutch operated electronically. I started using it with and original C4 when it was called "EGS" and with every car since the system has improved, it is now very close to a standard auto box but is more fuel efficient.

Some people criticize this type of box BUT a lot of this is from people who have not used it - I can't find any problems with the latest version; you could catch the earlier versions out but now they are excellent.

I'll sit back now and wait for the flack

The EAT6 is a conventional automatic transmission with epicyclic gears and torque converter. It has clutches to lock and unlock the various ratios, just as the 4HP20 and all other electronically controlled automatic transmssions of the last 20 years.

It is not an electronically controlled manual transmission.

I think that PSA will ditch those robotised single clutch gearboxes very soon. Maybe they already have. The eat6 will replace them. The problem is that the reliability is comparable or even worse than the dsg that is a work of art compared to the single clutch. I also think that there is nothing you could possibly to do to make them stonger: the clutch, flywheel and actuators live a very hard life . Those are normal wear items and cost silly money. The proper torque converter type gearbox should hopefully last the life of the car if you maintain it properly.

[daviemck2006]

I would like an auto but will only but a proper torque converter type. The thought of these robotised clutches breaking every year or so when they get older or higher mileage and costing over a grand to fix every time makes then useless and worthless to me. If I got one more than a grand cheaper than it's manual counterpart that is priced at £999 then I would take a chance!

I was offered a C3 Pluriel the other week with one of these funny gearboxes. I was tempted. The seller, our friend at Savoy reckons the gearboxes aren't anything bad as their reputation suggests, and if repaired properly the first time they break they shouldn't break again.
He did go into detail about what this entails but I can't recall.

I think it's the *properly* that's the important part here..

[daviemck2006]

If you had a c3 pluriel sensodrive is a recipie for bankruptcy. What with the 3 bits of the clutch that go at £1100 each you won't be laughing when the roof sticks open 100 miles away from home in the pissing rain lol. But then that maybe bother you after having that 3 wheeler [emoji12] [emoji23]
