If you're talking about the transmission, one with a split range, twin countershaft transmission will have one (9 speed, 10 speed) or two (8LL, 13 speed, 15 speed, 18 speed) auxiliary gearboxes. Trucks with something like an Allison auto will not.
6x4 has three axles, and two of them are live axles. 4x2 has two axles, and only one is a live axle.
I've run one which had a 6x4 twin stick, for a total of 24 gear ratios. Granted, the twin and triple sticks are dinosaurs by this point, but there are still some out there. The most you're likely to encounter in any current production truck is 18 on a single stick.
6x4=24
the lowest forward gear
Yes you can.
97 Chevy Z71 truck will not shift into third gear.
A 4x2 tractor with a GVWR of 33,000 lbs. would be. Most CL120s are 6x4 tractors, which would have a GVWR of ~54,000 lbs., making them a Class 8 truck.
You can fix a broken linkage in a 1999 Navigator truck by simply adjusting its Gear Shift.
truck start shift is hard to move in gear
The answer is 27 (6x4=24, 24+3=27)
just above gear shift on passenger side
6X4=24
