Sorry for stupid question.i was drive before different lorry -with automatic and manual gearbox(4 over 4).YESTERDAY WAS DRIVE RENAULT WITH 8 GEAR MANUAL POSITION.BUT gear stick have 2 button.yes first 1-4 gear,after front button up -will be 5-8.but wHAT is give this small button in the stick from left.■■?i turn up un down,no difference■■?
i would of said splitter 
Yes could be splitter.
Have Renault tried a switch for electric clutch operation (comfort clutch?) like manual MAN’s.
Did you try pressing the button during gearchanges to see what happened.

As has been said, it’s probably a splitter.
A splitter will give you an extra ‘half gear’ on each gear position. So it goes 1, 1.2, 2, 2.5 etc all the way up to sixteen gear positions.
They work off the clutch, so if you’re in, say, seventh, with the switch in the down position you flick the switch up, press and release the clutch, then it will change to seven and a half.
If you can’t work it out leave it in the ‘up/high’ position, otherwise you’ll be over revving at motorway cruising speed.

Most likely the Renault had a 16 speed ZF gearbox.
Four gear positions, as you say,eight gears by using the range change and the second button
is a splitter, which you can use to split each gear, giving 16 speeds in total.
To use the splitter, you need to flick the switch (pre-select) and then press the clutch to make it change
ratio.
As you found out, merely moving the switch will not change gear.

Nick.
It’s a splitter FFS.
You guys are so spoiled and it’s showing when one of you asks about the gear shifter 
You all need to get over here and have to drive trucks with gear boxes that were virtually obsolete in Europe by the 90’s
My 2011 wonderfully advanced (by US standards) has a damm fuller roadranger crash box in it

It’s only a crash box if you don’t know how to use it!
Is this a wind up ■■
Phantom Mark:

Who knows? I spent all day thinking that an ERF I once drove only had six gears.
Just for reference if this isn’t a wind up.
Any gear stick with 2 switches.
Front one is called the Range Change, ie high/low range
Side mounted switch is always the splitter, as explained above, to use the splitter you simply flick the switch and pop down the clutch without moving the stick to give you the half gear, you can on approach to a hill for example flick that switch in anticipation of your change and leave it alone, then drop the clutch pedal when you actually need that gear, ie it doesn’t all have to be done in one complete sequence.
Sticks with a single double position rotatation switch, called twin splits, rare these days and take a lot of practice to get good with. Pull away with the clutch and the switch in the lower position, whilst still accelerating move the switch to position 2, let off the throttle and next gear will engage, no clutch, move switch back to position 1, then move the stick to the next gear, let off the throttle, still no clutch, and so on and so forth, they key here being smooth because if you miss a gear you have to almost come to a standstill and start the proceedure again !! The first 2 gears are the hardest to master because they are the easiest to miss 
. , you really have to get a feel for those boxes to learn what rpm to shift and how smoothly and quickly to move the stick, downshifting too early is a very common mistake in those as well.
Forgive me if I missed anything re: twin splits, been 12 years since I had one

I used to like twin splits. Horrible until you work them out, then they’re the best box in the World.
Another common manual is the Slap stick as I call it, you basically go through the first set of gears then return the stick to centre and slap it over to the right, that changes you up into high range, once there you do the opposite to return to low, they also come with a splitter option on some trucks, you also find some with a collar ring around the gear stick to change range.
Think this covers most bases ■■

There were those Daf things with the collar thing** for the split.
**Usually known by a much ruder name, but I don’t know if that’s allowed here.
At least most surviving manual gearboxes actually have all the gears in the proper place these days.

Every Renault I’ve drove have had the knock across to change the range, if they had a splitter the earlier ones had a rotating collar and the later ones had a rocker switch.
What year is the op driving?

i now exactly how to use it, ‘Crash box’ is just a term for non synromesh as i am sure you know. I don’t double clutch either I only use the clutch to move off or stop.

I don’t doubt that you do, I just prefer to call it a constant-mesh or straight-cut 'box. Anything with “crash” in it just reinforces our negative image to the general public, in my opinion.

Also Scumia used the collar range change

Did my PSV in a Leyland Leapord with a ‘crash box’, always interesting to dive out of a small car into a big coach and have to concentrate on finding rev points etc with an instructor watching to see if you’re worth spending any money on
