4Y

This is the 4Y-series transmission assembly—a widely used power transmission component designed for multiple light-duty vehicles:

Applicable Scope

It is a versatile transmission tailored for vehicles equipped with the 4Y engine (common in light trucks, vans, and utility vehicles), adapting to scenarios like urban logistics, short-distance passenger transport, and light commercial operations.

Core Functions

As a key part of the 4Y powertrain system, it enables smooth gear shifting to adjust the engine’s speed and torque output: it provides sufficient low-end torque for starting and loading, while maintaining efficient power delivery during cruising to balance performance and fuel economy.

Design Features

The standardized structural design ensures high compatibility with 4Y-engine vehicles, while the robust metal casing and precise gear engagement mechanism enhance durability for frequent daily use. Its modular layout also simplifies maintenance and replacement.

Application Scenarios

As a mainstream transmission for 4Y-engine models, it supports daily operational needs such as urban cargo delivery, small-scale passenger shuttles, and light-duty utility vehicle use, delivering reliable and cost-effective power transmission performance.
