Specs for a 2012 L319

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.

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

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

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

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
