Gearbox work is where downtime hurts most, so this range focuses on the HOWO transmission parts that get replaced in the field: synchronizer rings and hubs, main and counter shaft gears, bearings, seals, shift cylinders and the shift and select cables that connect the cab to the Fast gearbox.
What this range covers
Fast (Faster) 9-speed, 12-speed and 16-speed gearbox internals, range and splitter cylinders, PTO assemblies, clutch release parts, gearbox mounts, and the WG-prefix shift cables and flexible shafts used across HOWO A7, T7H and TX models.
Why matching the gearbox code matters
Two HOWO trucks with the same cab and engine can carry different Fast gearbox variants, and the gear ratios, synchronizer rings and cable lengths differ between them. Before quoting a synchronizer or a shift cable, send the gearbox nameplate photo – the model code (for example 12JSD160T or 16S1650) decides which part is correct.
Shift cable wear – what to check
A cable that has stretched or lost its liner makes gear selection vague and, in the worst case, leaves the driver unable to select a gear at all. Check for free play at the lever, a frayed inner wire at the gearbox end, and any chafing where the cable passes the frame. Replacing both the shift and select cable together is usually the cheaper decision over a second workshop visit.
