Fast Gear 16JSD220TA Truck Transmission Assembly 16-Speed

Fast Gear 16JSD220TA transmission assembly – a 16-speed manual gearbox from the Shaanxi Fast Gear 16JSD series, built for heavy trucks, tractor units, truck cranes and special-purpose vehicles. It is a full-synchronizer box with an overdrive top gear: 16 forward speeds and 2 reverse gears, taking up to 2200 Nm of input torque and 380 kW of input power at a maximum input speed of 2600 rpm. The aluminum housing keeps the complete unit at 355 kg, and the 17 L oil capacity covers the service fill. Each unit ships as a complete assembly with shift linkage, sensors and fittings installed, and the nameplate carries the transmission model and production serial number for traceability.

Specifications

Key Features

• 16 forward speeds with a 0.83 overdrive top gear – keeps engine speed low at highway pace, which saves fuel on long hauls
• Full synchronizer design on all forward gears, so shifts stay smooth even for less experienced drivers on site or in traffic
• Double intermediate shaft architecture shares the load across two paths, which is how the box takes 2200 Nm without growing bulky
• Aluminum housing at 355 kg keeps weight off the chassis compared with cast-iron boxes of the same torque class
• Shipped as a complete assembly – shift linkage, fittings and sensors pre-installed, so swap-over is a bolt-in job rather than a rebuild
• Nameplate with model 16JSD220TA and production serial number on every unit, so what you order is what you receive

Signs of Wear – When to Replace the Whole Assembly

Individual gears and bearings can be serviced separately, but a worn box usually announces itself early. Watch for grinding that stays through a full synchronizer adjustment, a whine that changes with road speed in several gears at once, metal flakes on the magnetic drain plug, or oil losing level with no visible seal leak. When two or more of these show up together on a high-mileage unit, replacing the complete assembly with this 16JSD220TA is usually faster and cheaper than a full teardown, and it resets the whole driveline instead of one corner of it.
