12JS160T-1708010-17 12 Speed Trans Shift Knob Set

The 12JS160T-1708010-17 12-speed transmission shift knob set is a key operating component for SHACMAN heavy-duty trucks equipped with 12-speed transmission systems, including tractors, cargo trucks and engineering vehicles. It consists of a shift knob, a gear position indicator and an internal connecting structure, acting as the driver's direct control interface for gear shifting.

By operating the knob, the driver can accurately engage the desired gear, including low-speed, high-speed and reverse gears, preventing gear jams, mis-shifting and transmission wear. This is critical for driving smoothness, fuel efficiency and extended transmission service life.

The product is manufactured using high-quality materials and precise workmanship. The knob body is made of high-strength ABS plastic, which is wear-resistant, impact-resistant and non-slip, with a soft rubber grip layer for comfortable handling and reduced hand fatigue during long-distance driving. The gear position indicator adopts high-brightness LEDs, featuring clear visibility, low power consumption and long service life. The internal connecting rod is made of alloy steel, offering high rigidity and no deformation under load.

The installation dimensions, connection interface and gear stroke fit the SHACMAN 12JS160T transmission (for X3000, M3000 models) perfectly, allowing for direct installation without modification. It performs reliably under harsh conditions, including cab temperatures ranging from -30℃ to 85℃, frequent operation and minor impacts, without knob cracking, grip peeling or internal loosening.

Replacement is simple: there is no need to disassemble the entire transmission control mechanism. Simply remove the screws of the old knob, disconnect the wiring harness for the indicator, install the new knob, reconnect the harness and tighten the screws.

Each unit undergoes strict pre-shipment inspection, including durability testing (100,000 shift cycles without failure), grip comfort assessment and indicator brightness verification, ensuring consistent and reliable performance.

Precise gear positioning: Optimized internal structure + tight connection with the control rod ensure accurate gear engagement, no misalignment or slipping. Gear shifting accuracy 99%, 30% higher than ordinary knobs.

Comfortable & durable grip: Soft non-slip rubber grip fits the hand, reducing fatigue; high-strength ABS knob is wear/impact-resistant, life 2x longer than ordinary plastic knobs.

Clear gear indication: High-brightness LED clearly shows current gear, visible in strong sun or dark-helps drivers quickly identify gears, avoids wrong engagement.

Perfect for SHACMAN 12-speed transmissions: Made to 12JS160T transmission design-installation size, connection method, gear stroke match. No modification or adapters needed-saves 35% maintenance time vs universal sets.

This 12 Speed Trans Shift Knob Set (Model: 12JS160T-1708010-17) is only for SHACMAN heavy-duty trucks-X3000, M3000, L3000 models with 12JS160T transmissions. It won't work on other SHACMAN transmissions (10JS90T, 16JS200T) or other brands (FAW Jiefang, Dongfeng Tianlong).

Q1: Works on SHACMAN trucks with 10JS90T transmissions?

A1: No-10JS90T has a different transmission control structure and connection interface. It causes mismatched installation, wrong gear positioning, or inability to shift-safety hazards. Get the shift knob set for 10JS90T transmissions instead.

Q2: Gear position indicator not lighting up after new set install?

A2: First check wiring harness (no loose/reverse insertion). If good, inspect the corresponding fuse (replace if blown). If the fuse is intact, replace the knob set (rare indicator fault).

Q3: How to maintain the shift knob set?

A3: 1. Clean grip with a damp cloth often, no corrosive cleaners; 2. Check screws for looseness every 15k km (tighten if needed); 3. Avoid hitting/dropping the knob-prevent damage.

Q4: Is the grip layer replaceable?

A4: No, it's integrally formed with the knob body. If severely worn/peeled, replace the entire set for comfort and shifting accuracy.
