F18-1500010AB

1. Dual-Mode OE-Precision Compatibility for NEV & ICE Vehicles

The F18-1500010AB Transmission Assembly is uniquely engineered for dual compatibility with new energy vehicles (NEVs) and internal combustion engine (ICE) models, targeting compact and mid-size vehicles such as BYD Song Pro DM-i (PHEV), Geely Emgrand L Hi·P (PHEV), Changan UNI-V iDD (PHEV), and Chery Arrizo 8 (1.6T ICE). Adhering to strict OE standards for both powertrain types, it matches critical parameters with ultra-high precision: dual bell housing flanges (adapted for PHEV motor-generator interfaces and ICE engine mounts), 21-spline wear-resistant input shafts (compatible with both electric motor and ICE torque outputs), 27-spline reinforced output shafts, and mounting points with a tolerance of ±0.08mm. This dual-mode compatibility eliminates the need for platform-specific modifications, ensuring seamless integration with PHEV’s hybrid powertrain and ICE’s single power system, while avoiding TCU (Transmission Control Unit) communication mismatches or torque coordination errors.

2. Hybrid-Optimized Durable Construction

Gear System: Core gear sets are crafted from 18CrNiMo7-6 alloy steel, processed through vacuum carburizing (depth: 1.2-1.5mm), high-frequency quenching, and precision honing. This treatment achieves a surface hardness of HRC 60-63 and core toughness of ≥95 J/cm², enabling the assembly to withstand continuous torque loads of up to 300 Nm—perfectly matching the combined output of PHEV’s 1.5T engine and electric motor, as well as the standalone torque of 1.6T-2.0T ICE engines.

Housing: Die-cast from ADC12 aluminum alloy with a heat-dissipating ribbed structure (optimized for motor heat in NEVs), the housing resists vibration (up to 40g) and thermal deformation, maintaining structural integrity in temperatures ranging from -40°C to 140°C—adapting to the high-heat environment of PHEV motor operation and extreme climate conditions.

Sealing & Protection: Equipped with triple-lip Viton rubber seals (coated with high-temperature resistant silicone) and titanium-plated stainless steel gaskets, the assembly provides superior resistance to transmission fluid leakage and electrical insulation (critical for NEV high-voltage systems). The input shaft features a dual-labyrinth dust cover with a nano-hydrophobic layer, blocking dust and moisture in both urban and suburban driving scenarios.

3. Hybrid-Enhanced Shift Performance & Energy Efficiency

Rapid Shift Response: Equipped with an electronic-hydraulic integrated valve body and high-frequency solenoids (response time ≤180ms), the F18-1500010AB achieves seamless gear transitions, eliminating shift lag during PHEV’s mode switching (from electric to hybrid) and ICE’s acceleration.

Dual-Mode Gear Ratios: The 6-speed automatic configuration features hybrid-optimized ratios (1st: 3.200, 2nd: 1.900, 3rd: 1.300, 4th: 1.000, 5th: 0.820, 6th: 0.680). For PHEVs, lower gears prioritize torque multiplication for electric-ICE combined acceleration, while higher gears optimize energy recovery during deceleration; for ICE models, the ratios balance low-end torque and highway efficiency, improving fuel economy by 10-12% (ICE) and extending electric driving range by 5-8% (PHEV) compared to mismatched transmissions.

Adaptive Hybrid Logic: Preloaded with TCU programs that monitor PHEV’s battery SOC (State of Charge), motor output, and engine load, adjusting shift timing to prioritize electric mode (high SOC) or hybrid power (low SOC). For example, when battery level exceeds 30%, it maintains higher gears to extend electric cruising; when SOC drops below 15%, it shifts to lower gears to boost engine-driven energy recovery.

4. Cost-Effective Dual-Powertrain Solution

Offering OE-level performance for both NEV and ICE models at 30-35% lower than separate platform-specific OEM assemblies, the F18-1500010AB delivers exceptional value. Its modular design allows independent replacement of hybrid-specific components (motor coupling modules, energy recovery solenoids) and ICE-compatible parts (clutch packs, torque converters) without full disassembly, reducing maintenance labor time by 40%. It is compatible with both PHEV’s low-viscosity ATF 4400 and ICE’s standard ATF 3309 fluids, eliminating the need for specialized fluid inventory for repair shops servicing mixed fleets.

5. Rigorous Dual-Mode Quality Validation

Each assembly undergoes a 13-stage quality verification process tailored for NEV and ICE compatibility: 3D laser scanning inspection, Vickers hardness testing, hydraulic pressure leak testing (2x operating pressure), dynamic shift simulation (10,000+ cycles under hybrid/ICE torque loads), noise level measurement (≤72 dB at idle), high-temperature endurance testing (140°C for 6 hours), low-temperature performance testing (-40°C for 4 hours), vibration resistance testing (40g), TCU dual-mode compatibility testing (PHEV/ICE), dynamometer road simulation (electric, hybrid, ICE modes), torque overload testing, seal integrity & electrical insulation testing, and dual visual inspection (automated + manual). This ensures a failure rate of less than 0.4% within the first 60,000 kilometers.

6. User-Friendly Installation & Diagnostic Support

Installation: Features a 16-pin universal electrical connector with plug-and-play adapters for PHEV’s high-voltage TCU and ICE’s standard TCU, supporting automatic identification of powertrain type. Standardized mounting points require only professional basic tools, and a dual-mode installation guide (with PHEV/ICE wiring diagrams) is included.

Diagnostics: Equipped with enhanced OBD-III capabilities that transmit real-time data for both powertrains (battery SOC, motor temperature, engine load) to the TCU. Mechanics can use multi-brand diagnostic tools (e.g., Launch X431 V+, BYD DiLink Diagnostics) to retrieve hybrid/ICE-specific fault codes, perform energy recovery calibration, and monitor transmission health—reducing troubleshooting time by 45%.
