Turbo diesel + auto or manual for towing

[mynance]

On or off road auto, will outperform a manual except, maybe fuel economy

We're considering swapping the Captiva for a dual cab ute + canopy. I have a mate that tells me the single turbo diesels, when mated to an auto, because of the lag and amount of torque will chew the auto box up. He says it's not an issue on manuals or dual turbos because there's not the lag effect. He tells me that virtually all the auto's are made by the same company. They're basically sealed units as far as the car makers are concerned. They're warranted only as long as the tranny oil is warranted for. After a few years, there will be plenty of call for new automatic boxes in them

I don't really understand the logic of the advice your mate has given you.  The way I read it, it sounds almost contradictory

But what I am pretty sure of is that your mate hasn't even a basic understanding of turbos, turbo lag and automatic gearboxes....

Most, if not all of the common vehicle manufacturers make a turbo diesel, automatic 4wd.  Some now don't even make manual versions due to the popularity of the combination.  It's popular for numerous reasons including being superior for towing.  If auto gearbox failure was common with turbo diesel engines then you'd read about it.  Fact is it generally isn't a problem and for most people who tow regularly they don't experience any transmission issues over years and years of ownership.

Best advice is to pick a vehicle you like, then go ask an expert who regularly work on those types of vehicles about common problems with that model, as every vehicle has their quirks, strengths and weaknesses.

You can still get the transmissions flushed and refilled. What diesels utes have a twin turbo? You can put coolers on the transmissions as well.

Vw amarok. And nissan navarra. Both twin turbo

With engines getting more and more highly strung and smaller in capacity they need that many turbos to move them... specially with what people expect to carry and tow with them. "can I tow my 4ton caravan with this 2.x ltr engine?

octa-turbos is on the way

Can't wait for 8 turbo's! It is the future

engines will be 800cc by then

Was it someone on here said they (a car company?) were experimenting with fitting a super charger to a motor as well as twin turbo's.?
To try and eliminate the lag effect.
Wonder what the boost number would be?

As mentioned overheating the transmission fluid is the biggest problem for auto's as once it's gone over a certain temp (130-150c) the fluids lifespan is greatly reduced. I have fitted a larger cooler and temp alarm to my transmission lines after overheating and expensive rebuild. Since I have fitted the temp guage it's interesting to see how quickly temps raise when you hit a steep incline and also how quickly the temps fall when you reach lockup speed. Unfortunately on my Disco the lockup only works in top gear so most of the time is useless when towing uphill when you need the lower temps. My next tow vehicle will have lockup available in the lower gears as well as with the DMAX as this greatly reduces friction and therefore heat. I have also switched to full synthetic fluid which can handle higher temps as well.

He says he has had one (VW) and knows several others who have as well (Ranger, Triton, etc) and after a few years (4-5) they all basically sh!t themselves if they've done much towing.

As we want the new thing (whatever it ends up being) for better towing of the TrackAbout, this is a concern. And living in a BrisVegas, I'd prefer an auto (yes, I'm lazy, so shoot me!).

O.K. this is a mate said story   

Looking at a Trackabout --
 -  950Kg dry weight
 -  80Kg ball weight
 -  Maybe you might have about 400kg on board

I reckon any of the new utes on the market would not have any problems with this, either being a Manual or a Auto, single or twin turbo..  About the only time things could be a problem if you left the tyres pump up hard, and bogged it in deep sand on a 40C day etc, and be a total idiot but that would or could destroy anything.

What I would say here with the camper that your towing, just choose a ute that you like, and should that be a auto it should be all good, if you are worried how a particular ute would tow your trailer, a lot of the test drive vehicles have towbars on them, so just try the vehicle that your interested in with your trailer.

VW has had turbo and i/c in a golf or similar a few years back.

Actually on the previous page of this very thread 

Mazda has just patented, or applied for one, for a diesel engine with twin turbos PLUS an electronic supercharger to try to eliminate turbo lag.  It looks like a really interesting development and should appear in future generations of the BT50.

Thanks KB.

Still don't like very high nuimbers in boost.
It needs a lot of development in a motor to cope with high boost.
It costs to develop that sort of motor, so they're a very expensive option or they have to sell a big shed load.

New landrover engines use 53 psi boost. 177kw and 500 Nm. It will be interesting to see the longevity of these new type of engines.
