FAW Gearbox Overhaul 55892265
I previously owned a FAW car, which relies on advanced Chinese technology in its automatic transmission system.
With intensive use, I gradually noticed the appearance of several worrying issues: slow acceleration response accompanied by a shock or “jerk” (Net’a), especially when shifting between second and third gears, in addition to hearing a light “whining” sound that increased with the car’s speed.
It became clear that the transmission was suffering from internal wear and needed a comprehensive FAW Gearbox Overhaul.
The Optimal Solution: Sharara Auto Garage
I turned to Sharara Auto Garage in Kuwait, known for its expertise in maintaining high-tech Chinese cars. From the first moment, professionalism was evident:
Accurate Diagnosis: After dismantling the transmission, the team used advanced diagnostic equipment (Scanner) along with a thorough manual inspection.
It was revealed that the main cause was damage to the clutch rings and some clearance in the axle bearings, which led to weak oil pressure and a malfunction in the Valve Body.
Detailed Maintenance Plan: The engineer clearly explained the action plan, emphasizing the importance of relying on genuine spare parts that meet FAW standards to ensure reliable, long-term performance.
The plan included replacing damaged parts and complete renewal of the hydraulic solenoids.
Precise Procedures and Steps
The FAW Gearbox Overhaul was executed with extreme precision and according to the highest standards:
Comprehensive Disassembly and Cleaning: The transmission was completely dismantled, and all its internal components, especially the narrow channels in the valve body, were cleaned using special materials to remove any accumulated metallic residue.
Replacement of Damaged Parts: Replacements included the worn clutch packs, bearings, seals, gaskets, and oil filters with new, genuine components.
Programming and Calibration: Following reassembly, the Transmission Control Module (TCM) was precisely reprogrammed to ensure compatibility with the new parts and achieve optimal performance.
Final Results
After the work was completed, the results were remarkable and outstanding. All shifting problems and “jerks” disappeared, and shifts became smooth, rapid, and instantly responsive.
The “whining” sound was completely gone, and the gearbox temperature indicator settled at its normal level.
The FAW Gearbox Overhaul experience proved the competence of Sharara Auto Garage as a trusted place for maintaining FAW cars, guaranteeing the restoration of their factory performance55892265.
Definition of FAW Gearbox Overhaul
The FAW Gearbox Overhaul (Tajfeet) is a comprehensive procedure to address internal issues and restore the automatic transmission to its original performance level.
This process is usually necessary when signs of failure indicate internal damage that cannot be resolved with superficial procedures like an oil change.
The essential steps for a FAW Gearbox Overhaul are:
Advanced Diagnosis:
Electronic Inspection: Using modern diagnostic tools to check codes stored in the Transmission Control Module (TCM) and accurately identify faults.
Gear Oil Analysis: Detecting the presence of metallic residue or identifying abnormal oil characteristics (smell or color) which may indicate excessive friction.
Mechanical Disassembly and Maintenance:
Comprehensive Disassembly: Removing the transmission and completely disassembling its components to inspect the planetary gear sets, axles, and clutches.
Friction Component Repair: Replacing clutches and friction plates damaged by heat and excessive pressure.
Bearing Renewal: Repairing or changing damaged bearings that cause disruptive noise.
Hydraulic System Improvement:
Valve Body Maintenance: Cleaning or replacing control solenoids and adjusting the oil system to achieve compatible response.
Seal Replacement: Renewing all gaskets and seals to prevent any leakage and ensure stable oil pressure.
Reassembly and Recalibration:
Reassembly and Cleaning: Thoroughly washing the parts and carefully reassembling them before filling with new, dedicated oil.
Final Programming: Calibrating the electronic system to match its adjustments with the new parts.
Reasons for FAW Gearbox Overhaul
FAW cars, which are one of the Chinese options relying on advanced technologies, especially in automatic transmission systems, may, over time, begin to show indicators of advanced damage, making the FAW Gearbox Overhaul (rehabilitation) process necessary to restore their efficiency.
In Kuwait, Sharara Auto Garage is considered a specialized destination for dealing with these precise systems.
Here are the main signs indicating the necessity of a FAW Gearbox Overhaul:
1. Strong Jerk (Net’a) and Delayed Shifting
Cause: Wear of the friction plates and internal clutch packs leads to a weakened ability of the gearbox to smoothly transfer the car’s torque between gears.
Symptoms: Feeling a shock or a clear “jerk” especially when shifting between low speeds like 1-2 or 2-3, along with a delayed response from the gearbox to the accelerator pedal press.
2. Gear Slipping and High RPM Reading
Cause: Loss of hydraulic pressure due to damaged or cracked seals and gaskets, resulting in the leakage of transmission oil pressure.
Sign: A noticeable rise in the Engine RPM counter while the car’s speed remains lower than expected, which is known as “gear slipping.”
3. Gearbox Overheating and Burning Smell
Cause: Wear of gears and clutches unnaturally increases internal friction, raising the temperature of the gear oil (ATF).
Risk: The appearance of a strong burnt oil smell or the illumination of the temperature warning indicator on the dashboard, which indicates the oil has lost its properties and the gearbox is nearing total failure.
4. Continuous Abnormal Mechanical Noises (Humming or Whining)
Cause: Damage to the internal bearings (Rulman Bali) leads to a constant “whining” or “humming” sound that changes with the car‘s speed.
Action: This indicates metallic damage requiring a complete dismantling of the gearbox and replacement of the damaged parts to avoid further destruction.
5. Issues in Control Valves (Valve Body)
Cause: Accumulation of debris or blockage in the solenoid system (Valve Body) weakens the distribution of hydraulic pressure, causing shifting malfunctions.
Solution: Cleaning or renewing the Valve Body as part of a comprehensive overhaul, a sensitive step requiring high specialization.
