Have decided on a Nissan Patrol 2008 Diesel 3.0lt, but can't decide between auto or manual. Will be towing a 1250kg camper trailer and have heard manuals are better for towing - any opinions/experiences out there. Thanks.

IF and that is a big IF you are going to places where in the event of a breakdown you can get help quite readily then I would go for an auto. If seclusion is your bag where you may be days from help then go with a manual.

Auto's are great until the go wrong, many modern transmissions are full of electronics and less is more in my opinion when it comes to driving in deserted areas.

Even a simple thing like a low battery can leave you stranded with a auto, where with a manual car you can at least get a push start.

Cookie have you researched the problems with the zd30 motor, this would be a bigger concern.

2008 Madfisher, i wish people would drop the tag of the zd30 as being problematic, i dont think there is any concern with a 2008 zd30 as opposed to pre 03.

Furthermore I would like to think that anyone making a purchase (of anything) of that size would reasearch prior to posting the statement/question "decided on a..." on a public fourm

Pre 03 huh, my 2003 was plauged with expensive problems, radiator, exhaust manifold, head gasket, main engine seal, oil blowback in to the air filter. Happily traded it for a Landcruiser. My parents 2005 3.0L Patrol went bang, Nissan didn't want to know them because it was 11,000km out of warranty. Did they fix they problems, or is it just a case of the most recent ones haven't got enough miles on them yet for the familiar problems to start showing up? Apart from adding a common rail fuel system I am not aware of any major design changes to these engines. Don't get me wrong, they are a great engine, until the pin falls out.

Also Mike GU - a good point about research. Yes we have done plenty! Love Toyota LC too, but needing to be more budget conscious and love how the 08 Patrol handles in the city where I do a lot of the driving. Weekends/holidays are shared camping and 4x4ing experiences with the Simpson next on the agenda. Just wondered if anyone had issues with towing on auto.

Hi Cookie

Its a hard one, but I would go auto if your senario involves significant 4wding
and manual if not.

I have often considered the 3lt Patrol as an economical tourer with a tough chassis and not-withstanding the engines issues (which needs to be insured against) a factor which has been of more concern to
me is that the car has an older 4 speed auto , not the lovely modern 5 speed
auto slick shifer as in the 4800 and this makes the decision harder.

The manual is more fuel efficent accelerates faster and provides better braking which I feel is needed as the 3lt has smaller brakes.
However its 380nm of torque is high up in the rev range and it has to little down around idle.
This increases the clutch use.

For the above reasons I choose manual for light towing loads mainly on good roads.

A friend of mine used his 2002 auto 3lt for towing a 3ton drill rig for work everywhere until the engine died at 195,000.
The auto was an absolute must for moving this load in muddy/sandy or other bad conditions.
His load was excessive and he needed an extra transmission cooler.

When we would go 4wding his auto was always running out of breath and would take forever to get up big hills but it did get there.

Overall his car has proved to be almost as economical as my Petrol 4800(includes a $7000 engine repair bill)

Smaller than the equivalent Patrol Petrols.

Beginning 2001 with the 4800 petrol , its front and rear discs were increased in size and width , and the cylinder diameters were also increased.

Even the handbrake was changed from the transmission brake to the more modern little drum brakes that fit inside the rear discs.

Mmm o.k. you confused me a bit because Cookie was asking if the manual or auto ZD30 would be best and when you said the manual has bigger brakes I thought you meant the manual 3 litre had bigger brakes that the auto 3 litre which of course it hasn't. I am still confused by your comment because although the manual obviously has superior engine braking are you suggesting the 3 litre auto cannot stop because its brake are smaller than the TB48?

Hi Blown4by.

These things are relative , and my mates 3ton drill rig showed that you can do it with care in an auto (stop that is), mind you I think his discs were machined at 50-60k.

Auto's are much more reliant on brakes , and the auto combination with 3lt is the worst combination for braking and it comes up so in Patrol tests.

So with a big load you need a lot of care, and whole brake system in first class condition.

On one of the times we have had a new 3lt for a test my wife hit the brakes hard downhill and without feeling as she did with the 4800 and they actually faded out and gave her quite a fright.
The side by side comparsion is a bit revealing.

G/Day cookie 11

We have an 2008 Auto, the Cook wanted the Auto so when we travel she can share the driving on long trips, I was hesitant at the time, but asked around ect and we purchased a Diesel 3 LTR, we use it for towing the Caravan and what really surprised me, how good it is towing the Caravan up the Beach, it handles the Churned up Sand very easy when towing, I have had lots of 4x4's over the years and it's good as the rest, things go wrong with all types of vehicles and you get comments regarding the 3ltr Grenades, and Nissan's warranty, but most people who actually own them and get them serviced PROPERLY not DIY, haven't had problems, you keep on hearing of complaints like a Mate of mine ect, or mine has ex amount of ks on it and it sh#t it self ect, but have they really looked after the vehicle properly, have they Thrashed the vehicle ect, I'm fortunate to be able to turn the vehicles over on a regular basis through my business, but if I decided to keep the vehicle after the Manufacturers Warranty expired, I would look at getting an Extended Warranty for peace of mind, anyway only you can decide and know what you can afford.

Cheers

Cookie 11,

I had a manual my best mate an auto, I was towing alot burnt out the clutch, he was towing alot blew the auto gearbox. towing 2.3 tonne excavators.

$2200 for me $3200 for him me at 28k he at 84k make of that what you will .

I acually belive after driving mine and his that he had batter offroad performance he did not seem to suffer from lag as much we found he had better fuel econ as well. He was also better under tow good power from standing start and ease of driving. If I was to buy a new one now I would lean towards auto. His box blew because of heavy towing everyday of its life .If you think 88k of solid towing you wont jet close to that in a lot of years of camping. My clutch 28k more likley to get close to that if you know what I mean.

Dont quote me but a did hear a guy last year say that auto box covered under waranty clutch is not I would check this out if it is my pick auto.

I wont bag out nissans they are value for money and a bloody good truck but for us now we use 4.5 crusiers better for towing.

Hope this helps

I found it strange that Nissan never offered an Auto for the 3 litre Navara. Toyota did and the auto is probably their biggest seller. They offer an auto in the new 2.5 litre Navara now.

Cookie, my personal preference is always for manual, BUT...

With many of the smaller capacity turbo-diesel engines, the usable torque occurs only in a very narrow rev range which requires a lot of shifting if you're regularly driving in hilly terrain, and it will be worse if you're towing. I've only ever had a very brief test-drive of the 3.0L Patrol (manual) in the city so I can't comment conclusively.

If you have no personal preference either way, you might have to consider where most of your driving will be:
If cruising on straight, level highways, you might go for a manual (particularly if you enjoy a 'more active role' in driving)
If you're regularly running up and down the Great Divide or around a busy city, you might go for the auto (particularly if you're likely to get tired of swapping cogs)

Good food for thought thanks - no one has mentioned a greater towing capacity with a manual? Not sure if this is the case, might need to investigate further.

I don't know the towing capacities but a quick look in the owner's manual should tell you for both auto and manual (if different) - I'd expect either of them would be rated to tow more than double your 1,250kg camper trailer.

Some autos need an additional oil cooler fitted to prevent overheating when towing but I'd expect/hope the Patrol should be up to the task of towing 1,250kg without this modification.

Buy a 4.2 GU (manual only) and you can rest easy, knowing you will get to where you are going without a breakdown.. I think you can get a 2006 model in a 4.2.TDI Plenty of low km, late model 4.2s around... Buying a 3 litre is risky.... Michael

Gotta agree Michael, I cannot see where they have address the overboosting issues, caused by the egr fouling the maf, then sending the wrong signal to the variable vane turbo, leading to overboosting, leading to a cracked or holed piston.
The 4.2 s are as reliable as death and taxes.

Hi Michael & Pete
If the engine is a "common rail" then the problem with the MAF sensor and the Intercooler and turbo "should" be history????

But even so, the problems, pre common rail, can be addressed prior to catastrophy (all the info for this FIX is well documented on the Patrol forums etc.)

I still feel the 3ltr is a great engine let down by Nissan not addressing the problems and sticking their collective heads in the sand.

Never assume ANY of the pre common rail engines, un modified, are imune is a false and possibly catosrophic illusion, it just maybe that the later engines have not reached the milage that the problems occur.

The MAF sensor fouled by an oil soaked intercooler & wrong signal to the turbo to over boost, is the cause, and ONLY the common rail has addressed those issues.

My two bobs worth, thanks, Colin.

Good morning Colin,
Thanks for enlightening Me, was not aware the common rail was not relying on the maf.
The 3lt at work never missed a beat, but was sold at 80000ks.
Nissan had the rep once as the best engine builder in Japan, I dont think the renault link has helped.

Hi Colin, I havent had any personal experience with the 3 litre, unlike yourself. I merely have followed with interest, the long list of failures, of dissapointed and out of pocket supporters of a vehicle builder who let them down when it came to backup. My first '99 GU 4,2 has around 400,000ks on it and my current 2003 has 275,000ks, both have never had a mechanical breakdown and the '99 had the original clutch replaced last year. Not a bad run from an old tech engine. As Pete said.. Thanks for rundown on the reason for failure on the early engines, i didn't realise a solid conclusion had been reached.. regards Michael

I have a 2005 auto and have towed a camper of similar weight without any issues. The towing capacity of the auto is 2500kg. I wanted an auto and the handbrake won so we have the auto & I am glad for two reasons. Firstly the auto can change gear on the run say when on boggy beach sand. Secondly the torque converter allows the turbo to "spin up" to 1500 RPM quickly which is the lower limit of the turbo boost range so you get some pick up quickly which can be handy in traffic in comparison to the mates manual where he has to put his foot down and wait for nature to take its course. The only downside I see is slightly lower towing capacity and slightly less engine braking but in Low range and the auto held in 1st gear I have managed to control descents (including Mount Meharry 13 July 2009) quite easily with minimal foot brake use.

I use to own the manual. Wish I had got the auto.

Especially if towing, the clutch is an issue and until that turbo spins up, can be hard getting off the mark, especially on hills.

No such issue with the auto and the torque converter. Autos are great in the sand too.

Good luck.
