WEY Gearbox Overhaul 55892265
My WEY car experienced an annoying problem with its automatic transmission, where strong jolts began to appear during the shift between first and second gear in the morning.
Later, the condition worsened to slow gear response with a warning message appearing on the screen. I visited several traditional workshops, but unfortunately, they could not accurately diagnose the fault.
I finally decided to go to Sharara Auto Garage, known for its specialization in GWM cars.
The team started with a comprehensive diagnosis using OEM-Level Diagnostic tools. The engineer confirmed that the problem was mechanical and hydraulic, specifically wear in the clutches of one of the gear packs inside the transmission, which required a complete WEY gear overhaul instead of just an oil change.
The Professional Overhaul Phase – WEY Gearbox Overhaul:
After my approval, the Sharara Auto team began work, reflecting their expertise and specialization:
They meticulously disassembled the gearbox inside a clean and equipped workspace. They made sure to document the damaged parts with photos to illustrate the condition.
The clutch packs, oil seals, filters, and damaged parts of the Valve Body were replaced with genuine materials conforming to manufacturer specifications.
They performed a very precise cleaning of the Valve Body to ensure optimal oil flow and proper pressure.
The WEY gearbox overhaul process took four working days, and during this time, I was continuously informed thanks to the professional communication from the workshop team.
Programming and Final Result:
The most crucial step came after reassembling the gearbox and filling it with the specified oil. The TCU control unit was calibrated to match the new parts, achieving perfect integration between the mechanical and electronic components.
The results were astonishing:
The jolts completely disappeared, and the gear shifting process became extremely smooth and imperceptible. The engine regained its power and performance as if it were new. I also received a comprehensive warranty for the overhaul process, which gave me complete peace of mind.
I highly recommend Sharara Auto Garage services to WEY and TANK owners in Kuwait for their excellent service and high expertise in dealing with the complex systems of these cars.

Definition of WEY Gearbox Overhaul
The term WEY gearbox overhaul refers to a comprehensive process of repairing the automatic transmission, often of the multi-speed type, with the aim of restoring its full performance and operational efficiency.
This process serves as the final solution after the gearbox has suffered internal damage, whether mechanical or hydraulic. This step is necessary to address issues of wear, overheating, or lack of lubrication that affect the efficiency of the internal components.
1. Characteristics of the WEY Vehicle Gearbox
The gearbox of WEY cars relies on advanced and interconnected technology that requires careful attention during maintenance. The WEY gearbox overhaul process revolves around three main elements:
Hydraulic Packs (Clutch Packs): These consist of friction discs and steel plates used to transmit power and change gears. These components are frequently damaged due to aggressive driving or excessive heat.
Valve Body (Mechatronic Unit): It is considered the “hydraulic brain” of the gearbox, accurately distributing oil pressure through solenoids to activate the required gears.
Planetary Gear Sets: A group of components responsible for providing multiple gear speeds.
2. Steps of the WEY Gearbox Overhaul Process
The WEY gearbox overhaul process includes a series of specialized and precise procedures that must be carried out in advanced workshops:
Advanced Diagnosis: The fault code registered in the Transmission Control Unit (TCU) is checked to determine the source of the problem, whether in the clutch pack or the valve body solenoids.
Disassembly and Stripping: The entire transmission is removed and separated into its basic components for individual inspection and repair.
Cleaning and Replacement (Overhaul):
Replacement of damaged friction discs (clutches) and rubber seals to prevent hydraulic oil pressure leakage.
Cleaning the Valve Body and ensuring the integrity of the hydraulic solenoids, or replacing them as needed.
Inspection of gears and bearings, and replacement of any worn or damaged parts.
Precise Reassembly: All components are reassembled with high precision, adjusting internal clearances based on the original manufacturer specifications.
Lubrication and Reprogramming:
Filling the appropriate type of Automatic Transmission Fluid (ATF) to enhance performance.
Performing an electronic calibration (Adaptation) of the gearbox control unit to adjust shifts and oil pressure to suit the new parts.
3. Importance of the Gearbox Overhaul
The successful WEY gearbox overhaul achieves several benefits, including:
Improved Smoothness: Leads to the disappearance of annoying issues like jolts or vibrations.
Enhanced Performance: The gearbox operates with greater efficiency during acceleration and has better responsiveness.
Extended Lifespan: Protects the transmission from major future failures that could be extremely costly.
Overall, performing a WEY gearbox overhaul restores the car’s vitality and prolongs the life of the transmission, making it a necessary investment to maintain its long-term performance.
Reasons for WEY Gearbox Overhaul
The reasons leading to the need for a WEY gearbox overhaul fall into three main axes: mechanical related to wear, hydraulic related to oil and pressure, and electronic related to control systems.
1. Mechanical Reasons (Friction Component Damage):
This category includes faults that require the transmission to be dismantled and internal parts replaced:
Clutch Packs Wear:
Causes: Driving under harsh conditions such as traffic congestion and high heat can lead to the wear of the internal friction discs, limiting their effectiveness in transmitting torque.
Symptoms: Noticeable delay in shifting, especially when moving to higher gears, or complete loss of drive in a specific gear.
Strong Vibrations and Jolts:
Causes: Damage to bearings within the planetary gear sets or undesirable play resulting from metallic friction.
Symptoms: A distinct jolt when shifting into Reverse (R) or starting motion from a stop (D), often accompanied by abnormal noises.
2. Hydraulic Reasons (Oil and Pressure Problems):
Gear oil pressure plays a vital role in automatic transmissions:
Weak Oil Pressure:
Causes: Pressure leakage due to damaged seals and rubber rings inside the gearbox, or low oil level due to external leaks.
Symptoms: Delay in gearbox response during engagement, as it takes more time to execute commands.
Valve Body Damage or Blockage:
Causes: Accumulation of deposits resulting from clutch wear, leading to blockage of hydraulic passages or failure of solenoids.
Symptoms: Activation of the gearbox’s Limp Mode, which restricts speed, or the appearance of warning indicators on the dashboard.
3. Need for Programming and Specialized Repair (Precise Programming Advantage):
For advanced cars like WEY, mechanical repair alone is not enough to ensure optimal performance return:
Need for Programming and Calibration:
Causes: When major parts like clutches or the valve body are replaced, the electronic control unit (TCU) needs to adapt to the new parts through precise calibration of shift points and oil pressure.
Advantage at Specialized Centers like Sharara Auto: They provide programming tools conforming to manufacturer specifications (GWM) ensuring the transmission operates with high efficiency after the repair.
Gearbox problems in WEY cars necessitate a WEY gearbox overhaul when internal parts such as clutches or the valve body sustain significant damage that cannot be fixed by simple oil changes or the replacement of limited external parts.
Therefore, the overhaul is the optimal solution for restoring the entire drive system’s efficiency and performance 55892265.
