Repair of Automatic and Manual Transmissions in Lublin

How to Know When Your Transmission Needs Repair?

Imagine pressing the accelerator, but your car doesn’t respond the way it used to. Gear shifts become rough, the engine revs but doesn’t deliver power efficiently, or you struggle to engage the right gear. Worse yet, you hear metallic noises from underneath or feel jerks when accelerating. These are clear signs that your transmission needs immediate diagnostics.

First problem – slipping gears. If your car hesitates before accelerating, this may indicate worn clutch plates, low transmission fluid, or a failing torque converter in an automatic gearbox. In manual transmissions, slippage is often caused by a worn-out clutch or improperly tensioned linkage.

Second symptom – difficulty shifting gears. If the gear lever is hard to move, the issue may be worn synchronizers or a failing clutch. In automatic transmissions, rough gear changes often result from a faulty solenoid or a clogged valve body.

Third warning sign – jerking while driving. If you experience sudden jolts when shifting gears, especially when accelerating or engine braking, it could be due to contaminated transmission fluid or malfunctioning speed sensors.

Fourth issue – transmission fluid leaks. If you see red (automatic) or dark (manual) fluid stains under your car, damaged seals or a cracked transmission case could be the cause.

Final red flag – transmission warning light. If your dashboard displays a transmission icon or a “Check Transmission” message, the onboard computer has detected a fault, and diagnostics are necessary.

Ignoring these symptoms can lead to severe damage and expensive repairs. If you notice any of these issues, don’t delay servicing your transmission – it operates under extreme pressure, and even minor faults can quickly escalate into major failures.

Why Do Automatic and Manual Transmissions Fail?

The transmission is one of the most complex systems in a vehicle. It operates under constant stress, transferring torque to the wheels. But even the most reliable transmissions eventually wear out. What causes these failures?

The main reason – overheating. High temperatures break down transmission fluid, causing clutch plates in automatics to slip and synchronizers in manuals to wear out. Overheating is often caused by a failing torque converter or fluid leaks that reduce lubrication.

Second factor – low or poor-quality fluid. Without proper lubrication, gearbox gears and bearings run dry, leading to accelerated wear. In automatics, low fluid levels can cause solenoid malfunctions and issues with the planetary gear system.

Third cause – component wear. Clutch plates, synchronizers, and bearings all have a limited lifespan. After long mileage or aggressive driving, they start to degrade, leading to gear slippage, rough shifting, and unusual noises.

Fourth problem – electronic failures. Modern automatic transmissions rely on control modules, speed sensors, and solenoids. If any of these components fail, the gearbox may shift erratically or stop functioning altogether.

To avoid expensive repairs, it’s essential to regularly check fluid levels, prevent overheating, and address any early warning signs of transmission trouble.

How Is a Transmission Diagnosed and Repaired?

A transmission is a highly complex component, and even minor malfunctions can lead to serious issues. That’s why the repair process always starts with a thorough diagnosis, helping to avoid unnecessary expenses.

Step one – computer diagnostics. Modern transmissions are equipped with sensors that track any malfunctions. By reading fault codes, mechanics can determine whether the problem is related to electronics, solenoids, the torque converter, or mechanical components.

Step two – checking fluid level and condition. Low fluid levels or dark, metal-filled transmission oil indicate wear on bearings, gears, or clutch plates.

Step three – mechanical inspection. The car is lifted on a hoist, where technicians check for play in the system, unusual noises, fluid leaks, and the condition of the gearbox seals. Manual transmissions are examined for worn synchronizers, while automatics undergo hydraulic pressure tests.

Once the problem is identified, mechanics may either perform a quick repair without removing the transmission (fluid change, filter replacement, sensor repairs) or proceed with a full transmission rebuild if major damage is detected.

How Are Transmission Components Repaired and Replaced at Alians Serwis?

Transmission repair is a precise and complex process requiring expertise and careful attention to detail. At Alians Serwis, every step is carefully executed to restore full functionality and extend the lifespan of the gearbox.

Step one – disassembly and inspection. If the issue cannot be resolved with a simple fluid or filter change, the transmission is removed, cleaned, and completely dismantled for thorough assessment.

Step two – component diagnostics. Every key part is inspected, including gears, synchronizers, bearings, clutch plates, solenoids, and the torque converter (in automatic transmissions). The extent of wear is evaluated, and necessary replacements are determined.

Step three – repairs and part replacement. Damaged gears are either resurfaced or replaced, worn clutch plates and synchronizers are swapped out, and all seals and gaskets are refreshed. In automatics, the hydraulic system is checked, and any failing solenoids are replaced.

Step four – reassembly and testing. After repairs, the transmission is carefully reassembled, reinstalled in the vehicle, and tested under load. Mechanics ensure smooth shifting, noise-free operation, and a properly sealed system.

Thanks to this meticulous repair process, every transmission leaves the workshop working like new, providing a smooth and reliable driving experience.
