Deepal Gearbox Overhaul 55892265
I previously owned a Deepal S7 Hybrid and recently began noticing a problem with shifting that occurred when the auxiliary petrol engine was engaged.
There was an unusual vibration coupled with a “jerk” sensation during the power transfer between the electric and petrol systems, significantly impacting driving smoothness. I was very concerned, especially since hybrid cars require a high level of expertise to diagnose such issues.
I quickly turned to Sharara Auto Garage in Kuwait after hearing much about their outstanding expertise in maintaining Chinese cars and their complex hybrid systems.
The team conducted an accurate computer diagnosis, focusing not just on the mechanical gearbox but also examining the Power Control Unit (PCU) responsible for managing the switching between the engines.
They concluded that the problem was due to a hydraulic fault requiring an overhaul and repair of some components within the auxiliary transmission unit.
Specialized Deepal Gearbox Overhaul Stages
The Deepal gearbox overhaul process was performed with high precision at Sharara Auto, serving as a clear example of the professionalism required when dealing with hybrid cars:
Specialized Disassembly: The transmission unit was handled carefully due to its connection to the hybrid system; they disassembled the mechanical components and exposed the damage resulting from low oil pressure.
Internal Fault Repair: Damaged parts in the engagement unit specific to the petrol engine were replaced, along with all seals and rubber rings to prevent pressure leakage.
Hydraulic Control Unit Maintenance: The hydraulic control unit was cleaned and inspected with high precision, and affected solenoids that were not operating effectively were replaced.
Specialized Fluid and Programming: The gearbox was refilled with ATF (Automatic Transmission Fluid) strictly compliant with Deepal’s specific requirements, and the car was connected to specialized programming equipment to ensure optimal compatibility.
Results and Final Calibration
The final step was the key to restoring the car’s perfect performance:
Hybrid System Electronic Calibration: The technicians performed a precise electronic calibration of the control unit to ensure harmony between the petrol engine and the gearbox during transitions between systems. This step was crucial for the efficient operation of the hybrid systems.
Performance Improvement and Warranty: The vibration and jerking issues completely disappeared, and the transition between electric and petrol modes became smooth and imperceptible. I also received a comprehensive warranty covering the labor and components, greatly increasing my peace of mind and confidence in the garage’s service.
I strongly advise all owners of Deepal or any hybrid or Chinese car to go to Sharara Auto Garage to benefit from their deep expertise and professionalism in handling advanced technical systems.

Definition of Deepal Gearbox Overhaul
The term Deepal gearbox overhaul refers to a comprehensive process of repairing and restoring the transmission unit, whether it is designated for transmitting torque from electric motors or the auxiliary engagement unit for internal combustion engines in hybrid cars.
This process is deemed necessary when mechanical faults or hydraulic problems are noticed that affect the system’s efficiency, such as a drop in the quality of power transmission or a lack of smoothness in shifting, especially in hybrid vehicles.
1. Components Targeted for Overhaul (Hybrid and Electric Systems)
The Deepal gearbox overhaul focuses on targeting worn or damaged components. Key components include:
Auxiliary Transmission Unit (in Hybrid Cars):
Targeted Components: Internal clutches, Hydraulic Control Unit (Valve Body), seals, and bearings.
Cause of Damage: Clutch wear due to frequent switching between power sources or weak oil pressure.
Electric Vehicle Transmission Unit (EV Unit):
Targeted Components: Speed reduction gears, axle bearings, internal seals.
Cause of Damage: Mechanical wear of the gears or leakage of cooling and lubricating fluids.
2. Basic Procedures for the Overhaul Process
The Deepal gearbox overhaul requires specialized skills and expertise, including the following steps:
Diagnosis and Precise Disassembly: Specialized diagnostic tools are used to inspect the unit and identify the source of the fault, whether mechanical or electronic.
Replacement of Mechanical Parts: Replacement of damaged parts such as gears and clutches, along with changing seals and rubber rings to ensure proper sealing.
Control Unit Maintenance: The hydraulic control unit is cleaned or repaired, and faulty solenoids are replaced if necessary.
Reassembly and Electronic Calibration: The unit is carefully reassembled and filled with appropriate fluids, followed by programming and calibration of the Power Control Unit (PCU/TCU) to optimize its functions and ensure compatibility with the vehicle’s overall system.
Deepal gearbox overhaul is a precise repair process aimed at restoring the functional efficiency of the transmission unit, whether mechanical or electric, and eliminating issues related to vibration or difficulty in shifting in advanced cars.
Reasons for Deepal Gearbox Overhaul
The issues necessitating a Deepal gearbox overhaul fall into three main areas related to its advanced technology:
1. Mechanical Reasons in the Hybrid Engagement Unit:
These issues include wear of the internal or auxiliary clutches due to continuous switching between the electric driving mode and the petrol engine, stressing the engagement components.
Damage may also occur to the gears and bearings within the speed reduction unit due to lack of lubrication, causing noticeable whining sounds during high-speed driving.
2. Hydraulic and Electronic Reasons Related to the Control Unit:
The accumulation of impurities within the valve body responsible for directing oil pressure can appear, leading to a delay in power transfer or a loss of synchronization between the systems.
Additionally, gear oil leakage may occur due to damaged internal seals, affecting the oil pressure necessary for the system to operate efficiently.
3. Necessity for Precise Programming and Calibration:
After replacing any mechanical elements such as clutches or gears, electronic calibration of the control unit must be performed to ensure perfect coordination between the engines. A center like Sharara Auto is distinguished by having the specialized technical tools and expertise required for these operations on Deepal’s hybrid car systems.
In summary, Deepal car gearbox failures typically require an overhaul when there is clutch wear, hydraulic problems, or a need for electronic adjustment. These repairs rely on advanced expertise in dealing with modern Chinese systems55892265.
