1. Core Power Transmission
As the central component of Chery E3’s drivetrain, the transmission assembly transfers power from the 1.5L engine to the drive wheels. The torque converter (integrated into the assembly) replaces the manual clutch, using hydraulic fluid to transmit engine torque to the transmission input shaft—allowing the vehicle to idle smoothly when stationary and providing torque multiplication during acceleration. The internal gear sets and clutch packs then adjust the torque and speed according to the selected gear, enabling the vehicle to move at different speeds.
2. Automatic Gear Shifting
The assembly works in conjunction with Chery’s TCU to 实现 automatic gear changes without driver intervention. The TCU monitors vehicle parameters such as engine speed, throttle position, vehicle speed, and coolant temperature, then sends electrical signals to activate the assembly’s solenoids. The solenoids control hydraulic pressure to engage or disengage specific clutch packs, shifting between 4 forward gears and 1 reverse gear. For example, during gentle acceleration, the TCU shifts to higher gears at lower RPM to save fuel; during aggressive acceleration, it delays upshifts to maximize power output.
3. Torque Conversion & Multiplication
The integrated torque converter plays a key role in torque management. It consists of an impeller (connected to the engine), a turbine (connected to the transmission input shaft), and a stator (mounted on a one-way clutch). When the engine is running, the impeller spins, creating hydraulic fluid flow that drives the turbine. The stator redirects the fluid flow, multiplying torque by 2-3 times during low-speed acceleration—providing Chery E3 with sufficient power for starting and climbing gentle slopes. At high speeds, the torque converter locks up (via a clutch) to eliminate fluid slippage, improving power transfer efficiency.
4. Hydraulic Control & Regulation
The assembly’s valve body acts as its “control center,” regulating hydraulic pressure to various components. It contains a series of spools, valves, and passages that direct transmission fluid (Chery ATF 3309) to clutch packs, solenoids, and the torque converter. The TCU-adjusted solenoids modulate hydraulic pressure with high precision (±0.2 bar), ensuring smooth clutch engagement and disengagement. This hydraulic control system also includes a pressure relief valve to prevent overpressure damage to internal components.
5. TCU Communication & Diagnostic Feedback
The assembly establishes two-way communication with Chery’s TCU via the 16-pin electrical connector. It transmits real-time data such as transmission fluid temperature, gear position, and solenoid status to the TCU. The TCU uses this data to optimize shift timing and hydraulic pressure; if abnormalities are detected (e.g., low fluid pressure, solenoid failure), the TCU triggers a warning light on the dashboard and stores a diagnostic trouble code (DTC) (e.g., P0750 for shift solenoid A malfunction). Mechanics can retrieve these codes using Chery’s X431 diagnostic tool for quick troubleshooting.
6. Reverse Gear & Safety Interlock
The assembly includes a dedicated reverse gear train that engages when the driver selects “R” on the gear selector. A safety interlock system prevents accidental reverse engagement by requiring the brake pedal to be pressed before shifting from “P” (Park) to “R.” Additionally, the “P” position locks the transmission output shaft via a parking pawl, preventing the vehicle from rolling when stationary.
1. Chery E3 A19-Specific OE-Grade Compatibility
The Automatic Transmission Assembly 416AHA-1500010CA is exclusively engineered as a direct replacement for Chery E3 vehicles equipped with the A19 series 4-speed automatic transmission. It strictly adheres to Chery’s original equipment (OE) specifications, matching the original assembly’s bell housing dimensions, input/output shaft spline parameters, mounting point positions, and 16-pin electrical connector configuration with a tolerance of ±0.1mm. This precise compatibility eliminates common aftermarket issues such as improper powertrain alignment, transmission control unit (TCU) communication failures, or gear shifting asynchrony. Mechanics can achieve plug-and-play installation without modifying the vehicle’s drivetrain wiring harness or recalibrating the TCU, ensuring seamless integration with Chery E3’s powertrain system.
2. High-Quality Refabrication for Reliable Performance
As a professionally refabricated transmission assembly, it undergoes a rigorous 8-step renovation process: full disassembly, comprehensive component inspection (via ultrasonic testing and dimensional measurement), replacement of worn/aged parts (including clutch packs, solenoids, valve body spools, and seals), precision cleaning (using industrial-grade degreasers), reassembly with OE-matching components, vacuum leak testing, dynamic performance calibration, and 2-hour no-load running-in. All refabricated components meet or exceed Chery’s OE standards, ensuring the assembly delivers performance comparable to a new unit—with the added advantage of cost-effectiveness.
3. Durable Construction for Long-Term Use
Core Components: Gear sets are crafted from 20CrMnTi alloy steel, treated with carburizing and quenching processes to achieve a surface hardness of HRC 58-62, enabling them to withstand continuous torque loads of up to 200 Nm without tooth wear or deformation. The valve body is precision-machined from aluminum alloy and undergoes a surface anodizing treatment to resist corrosion and wear.
Clutch System: Equipped with high-friction organic clutch facings and reinforced pressure plates, ensuring stable engagement and disengagement even after 150,000+ kilometers of use.
Sealing System: Uses high-temperature resistant Viton rubber seals and gaskets, effectively preventing transmission fluid leakage and protecting internal components from dust and moisture ingress—suitable for diverse driving environments.
4. Optimized Shift Performance & Fuel Efficiency
The refabricated assembly features a calibrated valve body and upgraded solenoids that deliver faster and more precise hydraulic pressure control. Shift response time is reduced to ≤250ms, eliminating shift lag and shudder common in worn transmissions. The optimized gear ratio configuration (1st: 2.841, 2nd: 1.552, 3rd: 1.000, 4th: 0.700) is tailored to Chery E3’s 1.5L engine, balancing low-end torque for urban acceleration and high-end efficiency for highway cruising. This optimization improves fuel economy by 8-10% compared to severely worn original transmissions, translating to 0.5-0.8 L/100km fuel savings for Chery E3 owners.
5. Cost-Effective & Maintenance-Friendly
Offering performance comparable to a new OEM transmission assembly at 40-50% lower cost, the 416AHA-1500010CA provides exceptional value for Chery E3 owners and repair shops. Its refabricated design reduces resource waste, aligning with environmental sustainability principles. Additionally, the assembly comes with a 12-month/30,000-kilometer warranty, covering manufacturing and refabrication defects. The modular structure allows for easy replacement of individual components (e.g., solenoids, clutch packs) during future maintenance, further lowering long-term service costs.
6. Low Noise & Smooth Operation
The gear sets are precision-ground to a surface roughness of Ra ≤0.8μm, minimizing gear meshing noise. The upgraded torque converter features a damper spring with optimized stiffness, reducing vibration during torque transmission. These improvements lower overall transmission operating noise by 3-5 dB compared to worn original assemblies, enhancing driving comfort for Chery E3 passengers.
