Hilux dilemma

Currently running a Hilux HL3 on a 61 plate January 12 registered with 36k miles with rear veiw camera and touch radio but have been offered a 15 plate 3litre auto invincible with 30k miles by a mate that's just purchased a new auto model.

Is this a worthy upgrade or best keep mine? And how much is my HL3 worth ? Mine has tow pack but only towed for 200 miles total in maybe 5 occasions.
Is fuel going to be much worst with an auto?

it may well be there's something wrong (although I doubt it) with the auto box on the one I have as a company car at the moment, but if the 15 plate is one of the previous models, I'd make sure you give it a good test drive. The Auto in mine is terrible....

But to answer your question ref the fuel economy- I've been doing mainly long runs, and the fuel economy in the 3lt Auto invincible 63 plate I have is usually around the 25/27mpg (worked out using a fuel use app I have on my phone)

It never seems in the right gear
It takes an age to change (up or down- but particularly down, say when you want to overtake)
It clunks in and out of gear

Old school auto, not like these fancy 8sp dsg auto's with dual clutches

Mine works ok, but you have to learn the best way to drive it ;)

Amarok 8 speed, perhaps

That's got the ZF 8HP family auto box. Very good it is too.

Here is how the ZF 8HP works. It has so many overlapping 'cans' that it isn't possible to show the power flow for different ratios


For power flow you get a better idea from the Aisin 8 speed, which isn't quite the same but may give a better idea. In this video, Professor Kelly explains in some detail how the epicyclics work if I remember correctly. Aisin make transmissions for Toyota, Isuzu, Mitsubishi, Audi and Volvo among others.


Of interest here and not mentioned by Prof Kelly is that the Simpson gearset he speaks of was invented by Howard Simpson who was later heavily involved with the design of the Ford Select-o-speed tractor 10 speed powershift transmission gears but who had actually retired from Ford at that time. He kept on designing and refining gear sets well into his retirement.

Unfortunately it was put into production before it was durable enough with inadequate control mechanisms, against the wishes of chief engineer Harold Brock, who was sacked due to the internal politics involved. We all know the result [or do we?]

Edit
Forgot to mention that I think that Harold Brock went to work for Deere and pioneered their powershift. This is purely from memory so do not repeat before checking its accuracy. At his point I can't be bothered to do so. It just struck me just now and thought it might interest someone out there.

I remember when you posted this on another thread. It is pretty amazing engineering, especially the "bean tins"
