SAIC Motor Gearbox Overhaul 55892265
My car, equipped with an SAIC Motor engine, faced a serious issue with the automatic gearbox system after covering a long distance. I noticed a significant delay in shifting gears, in addition to a strange humming or whining sound while driving at specific speeds, and an unexplainable rise in the gearbox temperature. The situation led to wear in the gearbox parts, necessitating radical intervention.
I sought out Sharara Auto Garage in Kuwait, which has distinguished experience in SAIC Motor gearbox overhauls, and received professional service:
The inspection was carried out using advanced equipment capable of detecting electronic faults and mechanical diagnosis, which showed clear damage to the gear clutches and some planetary gear sets’ teeth.
The team then explained the action plan in detail, highlighting the importance of using genuine and approved spare parts, such as clutch packs and seals, while ensuring precise calibration of the internal valves in the hydraulic control unit.
During the SAIC Motor gearbox overhaul, supervised by specialized experts, the process went through multiple stages, starting with dismantling the gearbox and deeply cleaning its internal parts to remove old deposits.
This was followed by replacing the damaged parts, which included the clutches, friction plates, seals, and gearbox oil, in addition to checking the integrity of the oil pump and replacing the bearings if necessary.
After reassembly, technicians focused on precise calibration to ensure optimal performance, and they reprogrammed the electronic control unit to achieve compatibility with the engine.
The result was astonishing. The difference in performance was clear from the first drive: the strange noise disappeared entirely, shifting was smooth and responsive, with increased responsiveness and the gearbox temperature dropping to the normal range. This experience at Sharara Auto proved that the overhaul is the ideal solution for preserving the car’s lifespan and ensuring its efficiency55892265.
Definition of SAIC Motor Gearbox Overhaul
The SAIC Motor gearbox overhaul operation is a comprehensive maintenance procedure aimed at rehabilitating the automatic transmission of the SAIC Motor group.
This step becomes necessary when performance declines due to high temperature, the use of inappropriate oil, or covering extensive long distances.
The stages of the SAIC Motor gearbox overhaul process include detailed diagnosis of faults using specialized devices, followed by completely dismantling the gearbox to inspect and evaluate the internal parts.
Parts that need changing, such as worn clutch packs, friction plates, gears, and bearings, are replaced. Additionally, careful checks are performed on hydraulic parts, such as the oil pump, internal valves, and gaskets, to ensure the prevention of leaks.
All components are cleaned with special solvents before being carefully reassembled using new, specification-compliant gearbox oil.
Upon completion, the electronic control unit (TCM) of the gearbox is reprogrammed to ensure that the new shifting patterns are compatible with the renewed parts, leading to improved performance and restored efficiency as if the car were new.
The main goals of this type of maintenance are to improve shifting smoothness, eliminate noise issues, reduce excessive gearbox heat, and maintain the long-term optimal performance of the car and the transmission box.
Reasons for SAIC Motor Gearbox Overhaul
The gearboxes in SAIC Motor group cars, which include brands like MG and some Baojun models, are advanced systems that require meticulous care and regular maintenance.
The need for an SAIC Motor gearbox overhaul (comprehensive gearbox restructuring) increases when the transmission reaches advanced stages of wear or performance degradation, and this is where Sharara Auto Garage in Kuwait stands out as a specialized center for this type of service.
Here are the most prominent reasons why an SAIC Motor gearbox needs an overhaul:
1. Delay and Roughness in Shifting (Shuddering/Jerking)
Cause: Wear of the clutches and friction plates, which is the main factor leading to a lack of shifting smoothness.
Symptoms: Feeling a shock or “jerk” (Net’a) when shifting between gears, especially between first and second, or slow response when pressing the accelerator pedal.
2. Gearbox Overheating with a Burning Smell
Cause: Increased friction inside the gearbox due to worn clutches and gears, which significantly raises the temperature of the automatic transmission fluid (ATF).
Danger Signs: The gearbox temperature warning light illuminates on the dashboard, and a smell of burnt oil emanates from under the car, indicating the oil has lost its properties and is breaking down.
3. Hearing Strange Noises (Whining or Humming)
Cause: Wear of the gears or bearings (Rulman Bali), resulting in a constant “whining” or “humming” sound that increases with the car’s acceleration.
Potential Danger: Leaving the problem unattended may lead to broken gears and complete failure of the gearbox.
4. Loss of Hydraulic Oil Pressure
Cause: Damage to the seals and gaskets that maintain pressure within the transmission. When these parts are damaged, hydraulic pressure leaks occur.
Effect: This results in gear slipping (the engine RPM rises without the vehicle speed actually increasing), or the inability to engage a specific gear.
5. Accumulation of Metallic Deposits in the Gear Oil
Cause: Neglecting regular gearbox oil changes or using an unsuitable type, causing internal wear of components and the accumulation of metallic shavings (iron filings) in the oil.
Required Solution: A complete dismantling of the gearbox is necessary to clean the internal channels and replace the severely worn components.
