Double Intermediate Shaft Design
FAST transmissions feature a dual countershaft design that evenly distributes load, reducing gear stress and extending service life. This proven architecture handles high torque with minimal wear.
Optimized Gear Ratios
Wide ratio coverage (e.g., 7.46 first gear to 0.739 overdrive) provides exceptional startability and fuel-efficient cruising. The step design keeps the engine in its sweet spot.
Easy Maintenance & Parts Availability
With thousands of FAST transmissions across Nigeria, parts are readily available. The modular design simplifies repairs – gears, bearings, and synchronizers can be replaced individually.
Proven in Harsh Conditions
FAST transmissions are engineered to withstand extreme temperatures, dust, and vibration – ideal for Nigerian operating environments. Many units exceed 800,000 km without major overhaul.

Common FAST Transmission Issues & Solutions
With proper maintenance and genuine FAST Transmission parts, these issues can be resolved effectively.
Hard Shifting / Gear Grinding
Possible Causes: Worn synchronizer rings, damaged shift forks, low transmission oil.
Solution: Replace synchronizer assemblies and shift forks. Check oil level and condition – use recommended GL-4/5 80W-90.
Transmission Noise / Whining
Possible Causes: Worn bearings, damaged gear teeth, low oil level.
Solution: Inspect bearings and gears for pitting or spalling. Replace with genuine FAST bearing kits. Check magnetic drain plug for metal particles.
Oil Leaks
Possible Causes: Worn input/output shaft seals, damaged gaskets, overfilling.
Solution: Replace seals with OEM parts. Ensure breather is not clogged. Use correct oil volume (e.g., 3.3L for C8J series).
Gear Jumps Out of Mesh
Possible Causes: Worn shift rail detents, damaged gear teeth, weak interlock springs.
Solution: Inspect shift cover components. Replace detent springs and check shift fork engagement. May require gear replacement if teeth are worn.
Frequently Asked Questions
Q1: How do I identify which FAST Transmission model I have?
The model number is stamped on the gearbox data plate, usually located on the top or side of the case. Common models include 8JS118T, 9JS119, 12JSD200T – we can cross-reference your truck’s VIN if needed.
Q2: What is the oil capacity and type for a FAST Transmission?
Most FAST 8-speed and 9-speed transmissions require approximately 3.3L of GL-4/5 80W-90 gear oil. For 12-speed and 16-speed models, capacity ranges from 5L to 8L. Always check your specific model’s manual.
Q3: Can I replace individual gears, or do I need a complete set?
Individual gears are available and can be replaced separately. However, for optimal performance and life, we recommend replacing mating gear sets (e.g., main shaft gear with its corresponding countershaft gear) due to wear patterns.
Q4: How long does a FAST Transmission typically last?
With proper maintenance and using genuine FAST Transmission parts, these gearboxes often exceed 500,000-800,000 km. Many Nigerian operators report over 1 million km on original transmissions with regular oil changes.
Q5: Do you offer complete FAST Transmission units or only parts?
We supply both. We have new and remanufactured complete FAST Transmission units in stock, as well as individual components for rebuilds. Contact us with your requirements.
