Roewe Gearbox Overhaul 55892265
I was experiencing a growing problem with the automatic transmission of my Roewe RX5 car. It started with a delay in shifting during the morning and escalated to include a noticeable “jerk” when transitioning between low gears (1-2 and 2-3). Sometimes the transmission would enter Limp Mode, requiring me to turn the car off and on again for a temporary fix.
After attempts at several non-specialized workshops, I decided to visit Sharara Auto Garage in Kuwait, based on their excellent reputation and expertise in handling Chinese cars.
Their team performed an accurate computer diagnosis and determined that the problem was a hydraulic slip in a specific clutch pack due to its wear, in addition to weak oil pressure caused by a damaged Valve Body. This required a complete transmission overhaul.
Systematic Procedures During the Roewe Gearbox Overhaul Process
The maintenance and Roewe gearbox overhaul process at Sharara Auto Garage was highly organized:
Disassembly and Cleaning: The transmission was carefully removed and disassembled in a clean environment, with photographic documentation of the worn internal parts to transparently explain the cause of the fault.
Clutch Pack Replacement: All worn packs and discs were replaced, along with seals and rubber rings to ensure no future hydraulic oil pressure leaks.
Valve Body Maintenance: The Valve Body was carefully disassembled and cleaned of contaminants and metallic debris that were impeding the function of the solenoids, and any damaged solenoid was replaced.
Reassembly with Genuine Parts: They used high-quality spare parts and Automatic Transmission Fluid (ATF) matching my car’s specifications to guarantee optimal performance.
Programming and the Impressive Final Result
The final step involved precise transmission system programming:
Electronic Calibration (Adaptation): After installation, the team performed an electronic adjustment of the Transmission Control Unit (TCU) to harmonize it with the new parts, which contributed to achieving smooth and precise shifting.
Noticeable Improvements: The jerks completely disappeared, and the car returned to changing gears easily and smoothly without any delay. The engine also regained its power and quick response, and no emergency mode messages appeared anymore.
Warranty: I received a six-month warranty on the repair process, which reinforced confidence in the quality of the work completed.
I strongly recommend going to Sharara Auto Garage, especially for owners of Roewe or other Chinese cars, due to their extensive experience and high competence in this field.

Definition of Roewe Gearbox Overhaul
The term Roewe gearbox overhaul refers to a comprehensive maintenance and repair process for the automatic transmission, whether it is a traditional AT or a DCT type.
This process aims to restore the full mechanical, hydraulic, and electronic performance efficiency after the transmission has suffered major internal faults.
This step becomes essential when internal friction components or hydraulic control systems fail to operate as required. This is often due to excessive wear, high temperatures, or negligence in periodic gearbox oil maintenance.
1. Nature of the Roewe Gearbox and the Importance of Overhaul
The Roewe gearbox overhaul process focuses on the following key elements in the transmission to ensure its restoration to perfect function:
Clutch Packs and Brake Bands: These parts include the friction discs and steel plates responsible for disengagement and gear shifting. They are easily damaged, especially due to aggressive driving or high temperatures.
Valve Body: It is the unit responsible for distributing oil pressure to the main transmission components like discs and bands. Any fault in it can lead to performance deterioration, such as weak shifting or the sensation of jerks.
Torque Converter: (In the case of traditional automatic transmissions) The torque converter plays a fundamental role in transferring engine power to the transmission. It may require repair or replacement during the overhaul.
2. Stages of the Roewe Gearbox Overhaul Process
The Roewe gearbox overhaul process goes through specific steps that ensure an effective remedy for the root cause of the problem:
Diagnosis and Disassembly: The gearbox is inspected, and error reading tools are used to identify the damaged parts. The transmission is then completely disassembled in preparation for repair.
Cleaning and Replacement:
Replacing all damaged clutch packs and verifying the quality of discs and plates.
Changing rubber seals and rings to ensure the retention of necessary oil pressure.
Cleaning and maintaining the Valve Body while replacing affected solenoids.
Reassembly: Mechanical components are returned to their place with high precision after adjusting internal clearances according to original standards.
Relubrication and System Programming:
Filling the gearbox with compatible ATF or DCT Fluid.
Performing an electronic calibration (Adaptation) of the Transmission Control Unit (TCU) to adjust oil pressures and shift points in alignment with the new parts.
Roewe gearbox overhaul is considered the ideal solution for addressing internal component wear problems, such as the clutch system or the hydraulic performance failure of the valve body. This process restores the transmission’s ability to operate efficiently and smoothly as it was in its original state.
Reasons for Roewe Gearbox Overhaul
The reasons that lead to the need for a Roewe gearbox overhaul in Roewe cars are focused on three main axes that reflect internal issues that cannot be solved just by changing the oil or filter:
1. Mechanical Causes:
Clutch Pack Wear:
Cause: Aggressive driving, delays in changing the gearbox oil or filter, or high gearbox temperature, leading to significant wear of the friction discs and loss of their effectiveness.
Symptoms: Slipping between gears, delayed shifting, or complete loss of drive in some gears. Gear or Bearing Damage:
Cause: Metallic friction resulting from lack of lubrication or the presence of metallic debris.
Symptoms: Abnormal noises such as a “whine” or “grinding,” increasing with speed, alongside strong jerks with vibration.
2. Hydraulic Causes:
Valve Body Failure or Blockage:
Cause: Accumulation of contaminants and debris that block fine passages and impede the movement of control solenoids.
Symptoms: Limp Mode activation, violent jerks during shifting, or complete failure of the gearbox to engage. Internal Oil Pressure Leakage:
Cause: Damage to rubber seals and rings inside the gearbox, leading to weak pressure.
Symptoms: Noticeable delay in gearbox response, especially when starting the car while cold.
3. Need for Programming and Specialized Repair:
Electronic Calibration (Adaptation):
Cause: After replacing mechanical parts like clutches and the Valve Body, the TCU needs calibration to ensure compatibility with the new components.
Solution: Specialized centers like Sharara Auto provide advanced programming equipment that guarantees the restoration of the gearbox’s smooth performance.
Gearbox problems in Roewe cars necessitate a Roewe gearbox overhaul in case of major internal clutch wear or a Valve Body malfunction. These are deep-seated issues that require complete gearbox disassembly and component replacement with new parts to achieve the required performance 55892265.
