Specs for a 2012 L319

[uteman]

Question: Did all L319 diesel powered cars with 3 litre engine have 8 speed transmission?
A lady has an L319 for sale that is advertised as a 3 litre Diesel but the transmission is shown as 6 speed.
I always believed that it was only the 2.7 litre cars that had a 6 speed transmission

[Plane Fixer]

I have a 2012 3.0 with six speed which was built November 2011. The later 2012 models were all 3.0 as the 2.7 was dropped. From this model on had the eight speed with the two different tunes.

The 8-speed was introduced into the Australian market with the MY13 Discovery 4. The UK got the 8-speed with the MY12 Discovery 4.

If it has a shifting lever, it's 6 speed. If it has a rotary knob, its an 8 speed.

I’m not sure that it correct as I’ve seen non-facelift D4 with the 8 speed box in MY12 format in Australia. The majority are the facelift model when you see the 8 speed/rotary shift, but check carefully.

Only MY13 onwards Australian spec D4s are 8-speed. MY13 is pre-facelift. The facelift happened at MY14.
There are several incorrect advertised D4s on Carsales, three very quick examples of ‘MY13’ D4s with the extremely rare ‘8-speed stick autos’

kevlo: Thanks for the information.

If there are issues to watch for when purchasing either vehicle I will apppreciate any learnings given.

From what I've read over the years, the 8 speed is regarded as more 'reliable' (read: lasts longer) with some of the inherent problems of the 6 speed resolved.

The 6HP28 that comes with the 3.0L is a good box and doesn’t wear like the 6HP26 that came with the 2.7L. The 8HP is again better.
Very few convos around 6HP28 rebuilds but really, it comes down to their servicing and whether they’ve spent a lot of time towing a block of flats behind them. Unsurprisingly them towing their weight again behind them does wear them out quicker, along with if they’ve been serviced frequently, which really should be at 100,000km at a minimum

[Eric SDV6SE]

The 8spd behind the 3.0l makes for even more economical running. Fully agree with DJ, the 6spd is a good strong box, but like any complex mechanical thing, needs maintenance. Fluid change every 80,000km is a good start.

[veebs]

If you find a 6 speed you love, you can always change to the 8 speed later if it's really bothering you - not for the faint of heart, but Cambo on here has done it...

I quite like the lever as opposed to the knob, though i'm sure you get used to , and eventually like, anything. I have read a few failures of the knobs rising, though not enough to avoid the better 8 speed.

Given equal conditions what degree of difference might one see in the economy of the 6 speed versus the 8 speed

I did once own a 2012 year LR4 8 speed TDV6 and was amazed just how economical that car was.

What difference might I see in economy of a 6 speed SDV6 versus the 8 speed TDV6 that I once owned?
Given equal conditions of course

Others on here with the 8spd will be better placed to provide actual values but I understand savings of up to 2.0l/100km are possible with having the extra 2 cogs. Factors including tyre type (AT vs HT), tyre pressures, towing and state of tune all come into play of course

[loanrangie]

Apart from the extra 2 gears you also get higher diff ratios 3.21 versus 3.54.

An easier convo option might be a 6HP26 to 6HP28?

An easier convo option might be a 6HP26 to 6HP28?I don't think that would be worth the effort.

Based on your information I will ultimately go for an 8 speed. The one that I did have was fantastic on fuel. On a trip to Sheparton from Melbourne 6.8 Lt/100km

Bear in mind the dash computer is a filthy liar, and only by measuring litres and kilometres yourself will you come up with an accurate L/100km value :)

I just wish they stuck with the std shift stick like on the 6 side. That auto raising gear selector knob on the new 8spds is very fussy and known to get stuck. At least in the old 6spd it was still a mechanical linkage
