FAST 10JZSD120 is Twin Countershaft AMT transmission has 10 forward gears, the gear ratio steps are arranged reasonably, and has very outstanding fuel economy performance. With double intermediate shaft structure design and integrated with a synchronizer, the maximum input speed is 2600 RPM. The length of the 10JZSD120 transmission is 825.4 mm. The 10JZSD120 gearbox has 10 different gears, and the reduction ratio of each gear is different. 10JZSD1201 gear reduction ratio is 14.872, 2nd gear reduction ratio is 11.009, 3rd gear reduction ratio is 8.073, 4th gear reduction ratio is 6.020, 5th gear reduction ratio is 4.462, 6th gear reduction ratio is 3.333, 7th gear reduction ratio is 2.468, The 8th gear reduction ratio is 1.810, the 9th gear reduction ratio is 1.349, the 10th gear reduction ratio is 1.000, and the reverse gear reduction ratio is 14.247.

FAST 10-speed AMT series transmission have different models, with code J in the model name means mechanical transmission, with code Z in the model name indicates that the transmission is an automatic transmission, with code D in the model name means standard transmission, with code S in the model name means transmission with Double Intermediate Shaft design.

F·SHIFT is an AMT automatic transmission system designed by Fast Company using the OptiDrive modular system of WABCO Company. It not only adopts the technical advantages of Fast double countershaft transmission, but also adopts the advanced and mature control system and actuator of WABCO.

1. It is synchronized with CMI’ advanced design and sophisticated manufacturing, adapts to harsh working conditions, and has high-intensity and heavy-duty work capabilities.
2. The Holset wastegate valve makes the low speed performance more perfect and the power performance better.
3. The cylinder block and cylinder head adopt integrated design to prevent the occurrence of engine water and oil leakage. The parts are 40% less than other similar engines, and the failure rate is greatly reduced.
4. Using forged steel camshaft and crankshaft, high-strength cylinder design, many parts are cast on the cylinder, with high rigidity, high pressure resistance, good reliability and longer service life.
5. The cylinder liner adopts a platform mesh honing design, which effectively prevents oil leakage with a perfect geometric structure, and adopts advanced technology such as new piston ring components and gasket crimping molding to reduce oil loss.
