Transmission control module (TCM) failure indicates there is an issue with the valve body, and cleaning the filter screen can resolve it. Below is additional information: 1. Function: Transmission fluid is an oil product that keeps the gear shifting system clean, ensuring the transmission operates properly and extending the lifespan of the transmission components. 2. Transmission fluid can be used in all automatic transmissions on the market: In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicles may vary in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors that affect shifting quality.

The Transmission Control Module, commonly referred to as TCM, is the electronic brain that manages gear shifts in an automatic transmission. If it malfunctions, it means this component has failed, causing the transmission to operate abnormally. Common symptoms include rough shifting while driving, such as failure to upshift when it should, strong jerking sensations, or even warning lights on the dashboard, like a yellow gear icon. The causes of failure can vary widely—issues with the circuit board, software errors, damaged sensors, or moisture corrosion after driving through water can all trigger it. In such cases, it's crucial to pull over immediately and avoid forcing the car to drive, as a locked or completely failed transmission could lead to bigger trouble. The typical solution is to visit a repair shop for a computer diagnostic scan, with most cases requiring a full module replacement, costing several thousand yuan. Regular maintenance, such as checking wiring seals and updating software, can help reduce risks—after all, safety comes first.

How to Remove Odors from a New Car?

Here is relevant information about removing odors from a new car: Place Plants: Place some air-purifying plants inside the car to maintain effective circulation of odors. You can also frequently carry fruits that have odor-removing properties, such as pineapples, oranges, etc. Remove Plastic Film Promptly: When a new car is purchased, there is usually a plastic protective film covering the seats and other interior components to maintain their newness. These protective films should be removed promptly, as they are also a source of odors. The films block the natural airflow of the seats' own scents, preventing effective odor removal. Air Circulation: First, ensure proper air circulation inside the car by opening the windows. If necessary, open the doors to allow air exchange between the interior and exterior. While driving, try opening the windows for ventilation.

How many turns to fully lock the steering wheel?

Generally, it takes two to two and a half turns to fully lock the steering wheel by turning it counterclockwise or clockwise to the end, which is called 'steering wheel locked'. Short-distance full lock: Used for short distances in cars and other vehicles, allowing the vehicle to complete a significant steering action with minimal movement distance. Avoid continuous full lock: When turning the vehicle, if the steering wheel is fully locked, the power steering pump pressure will increase several times or even more. Continuously locking the steering wheel will shorten the lifespan of the power steering pump more quickly, so it should be avoided. Right full lock means turning the wheel one and a half turns to the right, and left full lock means turning it one and a half turns to the left.

What are the symptoms of a burnt clutch plate?

Symptoms of a burnt clutch plate include clutch slippage and lack of acceleration. Specific details are as follows: Clutch slippage: Clutch slippage refers to a situation where, during normal driving on flat roads, the vehicle may seem mostly normal, but with a slight reduction in power that might not be noticeable. However, when attempting a hill start with partial clutch engagement and throttle coordination, the vehicle body will noticeably shake, and starting on a slope becomes very difficult. This generally indicates that part of the clutch plate may be burnt. Of course, it could also be due to an uneven clutch pressure plate. In any case, if such symptoms occur, it's best to get it repaired to ensure the vehicle can operate normally. Lack of acceleration: If the clutch plate is burnt, typically no matter how much you press the accelerator, the speed won't increase. Even if the engine revs reach the redline, the vehicle will still move at a snail's pace. This suggests that part of the clutch plate is burnt but not completely destroyed.
