1358 302 203 3rd Speed Gear

1358 302 203 3rd gear is a core shifting and transmission component of the main gearbox in the ZF 12TX series automatic transmission, responsible for 3rd gear power switching and torque transmission.

Adopting a precision gear grinding process, it meets the standards for coaxiality and meshing accuracy, conforming to the assembly specifications of the internal gearbox assembly.

The surface is treated with strengthening, anti-corrosion and wear-resistant technology, adapting to complex road conditions such as long-distance trunk transportation and engineering heavy-duty operations.

It effectively prevents faults including gear slipping, transmission abnormal noise and power loss. With original universal specifications, it is easy to disassemble and install, offering high cost performance for maintenance and replacement.

This product is an original 3rd gear for ZF 12-speed AMT gearbox. It is precisely machined from high-grade alloy steel through carburizing and quenching treatment, featuring high tooth surface hardness, excellent impact resistance and wear resistance.

With accurate tooth profile and tight meshing, it ensures smooth gear shifting without jerking, as well as quiet operation with no abnormal noise.

Boasting high overall structural strength, it resists tooth chipping, gear jumping, wear and deformation under long-term heavy-load and climbing working conditions.

Manufactured in strict accordance with original factory process and dimensions, it supports direct in-situ replacement and installation with superior compatibility. It effectively extends the overall service life of the gearbox and serves as a high-quality original part for maintenance and replacement.
