As a professional driver, I most certainly can.
You are forgiven, there are professional drivers and people who earn a living, filling a driver’s seat. You are, or were quarter of a century ago, firmly in the latter camp.
The only thing the two gearboxes have in common is the manufacturer and the ability to be changed clutchlessly. You have never operated either, so before you make a bigger fool of yourself, drop the subject.
I loved a 13 speed. The irony of the 18 being that it was introduced to cope with the higher torque of modern 500~600hp engines, negating the need to split the bottom range. It was handy though.
You might have missed it but the question was preselection of torque sensing ( accelerator ) actuated split shifts.So you’re saying that you are so good that you can guarantee no accelerator and torque input changes between pre selection and required actuation.Obviously depends on your definition of pre selection.
I’m wondering in this case if they just mean the full shifts combined with the split shifts like 3rd to 4th which would obviously mean clutch actuated and bust the myth of a floated upshift shift.Because you obviously can’t get a torque sensed low split from a lifted throttle for the upshift.
Define torque actuation if not the same thing as by the accelerator ?.
Which we all know was definitely the usual way of actuating a Fuller splitter.I have at least driven and understand the differences in the form of Ecosplit, ZF 12 speed and Spicer all being clutch activated.
In addition to what was from memory the unusual Fuller option of clutch activation.Also torque activation depending on specification like MAN 13 speed.
Obviously only the former can be preselectable because there’s no way of preselecting a split shift without then making any accelerator and torque adjustments between that and commanding the shift.
Pre selectable clutch actuation and torque sensing actuation sounds like a weird contradictory combination unless it was switchable.
But agreed definitely proof that I never drove a twin split which I’d always wondered if I’d confused in the case of the MAN.
But torque sensing 13 speed v most other type of splitter should suffice for the purposes of making sense of that advert.
You’re deffo out of your depth, chap. The accelerator doesn’t actuate the shift. Backing off the accelerator momentarily breaks the torque, which itself actuates the shift.
You’re not entirely right about the 13-sp ‘box either, as it depends on which way it’s been plumbed as to whether you can float it - and I’m not going into all that detail yet again. We’ve been through all this stuff dozens of times on here and you pop up again as if nothing ever happened, with the same nonsense you were spouting ten years ago. It wouldn’t be so bad if you weren’t pontificating about it as if you knew how it all worked in the first place. Thank God you’re here to teach us how a Fuller works. You’ll make GOM’s evening this time!
Do you have any idea what you’re talking about, because I don’t?
You obviously have no idea what torque sensing is, which is why you insist the clutch has to be used.
Bit harsh there SDU. It’s not him that has no idea about torque sensing, it’s ChatGPT 
After all, there’s only so much you can plagiarise.
I only got up to 13 on the Fuller so i will keep quiet. I did get 18 in a few Renaults but they were synchro which is frowned upon by some on here …. well one .Apparently that half a second between changes makes all the difference.
@ramone was the 18 a Renault or ZF box?
An 19speed RoadRanger is just a 13 that you can split the bottom of the box too.
Just looking at some of the old 50s and 60s motors on here, many of the type my Dad used to drive, Albions, Commers, BMCs etc.
I know you knew nothing else at the time but you old guys deserve a medal for driving stuff like that on long distances…..I remember some of the crap my Dad drove, uncomfortable, basic, would not pull and with poor brakes….many of them death traps due to lack of regulation.
The oldest stuff I have driven were old 70s motors in the 80s, some of them were bad enough.
The quality of trucks in comparison to those old motors has improved by 100 years in 50.(if ya see what I mean)
The motor I drive is like a big car and a mobile home, only problem is the similarity between modern trucks and a car, attracts crap drivers, not like those in your day who needed actual skills to drive them.
New drivers today just take the quality of trucks for granted, even I used to slag off my Actros, but it’s like comparing a modern flat with a cave when you look at a 50s or 60s Atkinson and the like.
I remember as a young kid my Dad commenting on the ‘new Volvo 86s, that motor in the UK was the start of it all imo.
So even now (the same as when I started) I have the utmost respect for you old guys who were drivers the same time as my Dad.
Just thought I would say that.
…..me as a ‘‘young kid’‘ in comparison.
I think but could be wrong that the ones i drove were Renault boxes.Noisey things sounded like a bag of spanners on tickover and knock over for the range change.
Think my old Renault 310 had a ZF synchro box
If it was in fact a Renault box, it was very similar, even the same as a ZF.
Loved that motor btw.
Yes, the Renault B18 was actually a 16-sp syncro box IIRC and I really didn’t like that knock-thro’ arrangement, though I have to say it was slicker than the ZF knock-through equivalent.
@robroy and @les_sylphides quite possibly the Renault box was a ZF built under licence.
The only reason i didn’t think it was a ZF is because they sounded terrible on tickover.We had 2 290 GTs (GT 
) a 340 and a 365 and they were all the same.We had a couple of 365s on hire and again really noisey on tickover.I drove a Mercedes with the knockover box which i think was a ZF and it was really stiff. We had a few and they were all the same so that could have been Mercs installation .Horrible things
They were MOSTLY happy days. My first motor, 1959, was a Ford 4D (Harrisons of Dewsbury), next was Commer TS3 ( Fred Chappell) , moved on to my all time favourite, my AEC Marshall (5177 WY), next Atkis (150 Gardner), then various ERF’s, Fodens, and many more in between.
I enjoyed my life ‘on the road’, for me they were happy days.
I’ve never used any of the 4/5/600 automatic modern stuff, best I could manage was a 350 Cummins, 9 speed Fuller, 3 axle, Foden
Yep chalk and cheese compared with today’s job I would reckon.
Odd that the same ‘box would feel totally different in other trucks. I had a MAN F2000 with that same (16 speed) ‘box installed and absolutely loved it! The truck in question already had covered a million clicks when I got it, so it was quite smooth with the gear changes.
