How to Repair a Faulty Automatic Transmission?

[McCamille]

Here are the repair methods for automatic transmission failures: 1. Faulty electronic components in the transmission: Solution: Computer diagnosis and replacement of damaged electronic components. 2. Severe wear of mechanical components in the transmission: Solution: Repair the damaged mechanical components. 3. The engine or ABS sends incorrect signals, interfering with the transmission: Solution: Inspect the engine and ABS, and repair the damaged electrical components. 4. Oil leakage: Solution: If oil is seeping from the transmission housing or oil pan, it could be due to aging seals causing poor sealing or manufacturing defects leading to porosity in the housing. Replace the corresponding parts. Transmission usage precautions: 1. Water ingress in the transmission is very subtle and hard to detect. By the time the vehicle shows abnormal behavior, the transmission may already be severely damaged. If coolant is frequently low without external leaks or there are oil traces in the coolant, it could indicate water ingress in the transmission. This must be taken seriously and repaired promptly. 2. If you hear unusual noises from the transmission while driving, and the noise increases with engine speed or vehicle speed, stop immediately for inspection and repair to avoid further damage.

I've been driving automatic transmission cars for many years and have encountered transmission failures several times. The most common issues seem to be gear slippage or delayed shifting - these small problems should never be ignored. First, park and check the transmission fluid: see if the level is normal, and whether the oil appears blackened or has a burnt smell. If the fluid is dirty, it needs prompt replacement, but don't attempt this yourself - it's best to drive to a professional repair shop. They have diagnostic tools to read trouble codes, which might indicate problems like failed solenoids or worn clutch plates. I once experienced jerky shifting on the road, but fortunately addressed it in time to prevent more serious damage. During repairs, technicians typically disassemble and inspect internal components, replacing any damaged parts. Remember, regular maintenance can significantly reduce such failures - for example, changing the fluid every 40,000 kilometers.
