Yes you canand I used to my self until our fleet mechanic explained to me why it is better to break the torque with the clutch.

Half the people I work with use the term trans the other half refer to gearbox, all or most service manuals use the word transmission.The 18 speed I drive at the moment has 'eaton fuller transmissions' written on top of the gear lever.The biggest differance for me is that trans is a dam site shorter word to type.

Hate to see how you would get on explaining an I shift gearbox then lol Also if not using the clutch its about timing and smoothness,That way you are not having to "break the torque" as your mechanic put it. My father in law did well over 1million In one truck,never had any gearbox issues at all. I think it comes down to being an operator above driver or steerer.

just had my first read of these messages re truckies. My son is a long haul truckie and I had the "pleasure" of riding with him a while ago. Do all car drivers think they are indistructable when pulling out in front of these big rigs. I was actually scared as a passenger in a truck because of the thoughtless drivers out there. These rigs cannot stop as quickly as a car, nor swerve to miss you. They have a hard job to do, long days, mostly boring, but they have to keep their wits about them because of the idiots on the road. I won't ever get into his truck again. My "baby's" life is in your hands.

Every once in a while I notice a truckie doing something stupid. But the reason these events stick in my memory is because they are so rare.
In my experience, on the open road the average truckie drives a hell of a lot more steadily, predictably and courteously than the average driver of a small vehicle.

Haven't had the chance to try an Ishift yet but have heard that it's one of the better auto shifts around only driven one early auto shift on a 18 speed and hated it but apparently they have improved the later ones. Next time you drive a roadranger try this, change gears only useing twofingers on the lever first with clutch then with the throttle only and see if you notice the differance in how the lever slips out of gear that extra weight you feel is what adds to the wear on forks and sliding clutches.

We have a couple of snapped selector shafts out of volvo R1000s sitting about at work, only kept for the purpose of explaining to drivers why using the clutch is so important. They sharpen up pretty quick when you actually show them what it can do

The I shift is fluid and pulse driven,so it cuts down on moving parts to be broken.
yuuhoo,

By fluid do you mean as in a torque converter! or that the shifts are made by fluid ie hydraulic/

No, the I shift is a manual gearbox less syncros operated by electric solenoids.
Sorry chris051,I nolonger have my VCVA Passwords,otherwise I could give you a fully blown diagram,and operation.

I'm second guessing now as I haven't worked on one but have been told it is like eaton, Isuzu and ZF when it is a manual box with electronic/pneumatic operated clutch and selectors. Looks like it is after reading thru this brochure.
those gear ratios probably cross over to the three pedal ones and has a conventional but auto operated clutch, no fancy fluid coupling to transmit drive.
