When the AMT was launched in 2025 Hino wanted to make clear that this was not a completely new transmission but rather was a development of a manual synchro box used in Japan. In AMT format it features a counter shaft brake to facilitate quicker and smoother shifts.
It is fundamentally a three-speed with a dual range configuration plus a splitter to achieve the 12 speeds. The range change is on the 6-7 shift and, as such, takes fractionally longer to achieve. In manual operation the driver quickly adapts to this and holds off from upshifting too early.
The rear axle ratio has been changed from 5.6:1 to 5.2:1 in order to down-speed the engine and improve fuel efficiency in the sweet spot around 1600-1700rpm.
The introduction of the 12-speed AMT complements the Allison fully automatic transmission which remains the driveline of choice for Hino 700’s under 350hp and has for a long time proved ideal for metropolitan applications.
Hino 700’s with the 480hp version of the 13.0 litre engine are fitted with the 16-speed ZF AMT which incorporates the incredibly effective ZF Intarder. Diff locks are a feature of all of the Hino 700 Series range.
On Day Two of our trip, about midway on the long climb from the coast up the Clyde Mountain in an FS 2636 6×4 curtainsider, another vehicle up ahead encountered a problem (possibly driver related) and we, along with other traffic, were forced to come to a complete halt.
After considering twisting the transmission selector dial to the crawler gear ‘slow forward’, we elected to leave it in ‘Drive’, toggle down to first gear, move the Hill Hold release to ‘slow’ and simply fully apply the accelerator. Despite the Hino’s weight and the incline, this resulted in a very smooth take up and we were quickly manual shifting through the higher gears. Easy.
In concert with the rotary dial on the dash which basically selects forward or reverse, the transmission can be controlled by a wand located next to engine brake lever, meaning there is no need to take a hand off the steering wheel.
In ‘Eco’ mode with the Adaptive Cruise Control activated the transmission will neutralise whenever coasting is possible to save fuel and the reconnection of the driveline is very smooth.
In line with the rest of its range (including the Euro VI 500 Series coming next year) the Hino 700 Series now comes with a five-year warranty.
The versatility of the Hino 700 Series is impressively demonstrated by the disparate line-up of vehicles provided for this exercise. From a prime mover pulling a loaded skel trailer, an 8×4 tilt-tray loaded with an innovative Hino Hybrid recovery vehicle, several versions of curtainsiders, air and leaf spring tippers, and even a 6×4 rigid stock crate, every Hino proved to be up to the applications for which they have been developed.
Whether it be civil works, metro and regional delivery or specialised applications such as the tilt-tray, the Hino 700 Series is up for the task.
