Here are the reasons for excessive transmission temperature and a burning smell: 1. Clogged filter screen: The transmission hydraulic pump's oil suction filter screen is clogged. 2. Poor radiator performance: The radiator's heat dissipation capacity is insufficient, and the machine is severely overloaded. 3. Hydraulic pump damage: The transmission hydraulic pump is severely worn or damaged, causing significant system leakage. 4. Abnormal proportional valve: The torque converter's inlet regulating proportional valve is malfunctioning. 5. Clutch slipping: Transmission clutch slipping can also lead to excessively high transmission oil temperature. Note: The transmission allows the vehicle to reverse while maintaining the engine's rotation direction. The transmission, also known as a gearbox, is a mechanism used to alter the speed and torque from the engine, enabling fixed or stepped changes in the gear ratio between the output and input shafts.

How to Identify Car Gears?

P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport Mode), L (Low Gear). Below is a detailed introduction to car gears: 1. P Gear is the Parking Gear: When the gear lever is in the P position, the transmission is in neutral internally, but the output shaft is mechanically locked. At this time, the car will stop in place even without stepping on the brake, and it is generally used for long-term parking of the car. When engaging the P gear, the car must be completely stationary. Do not engage the P gear when the car is not fully stopped, and always apply the handbrake. When parking on a slope, you need to apply the handbrake first and then engage the P gear. 2. R Gear is the Reverse Gear: When the gear lever is in the R position, the rotation direction of the transmission output shaft is opposite to that of the engine, allowing the car to move backward. When engaging the R gear, the car must be completely stationary. Do not engage the R gear when the car is not fully stopped. 3. N Gear is the Neutral Gear: When the gear lever is in the N position, the gears inside the transmission are in an idle state, and the clutch is not engaged. The load on the transmission is minimal at this time. The N gear is generally used for short-term parking, such as waiting at a red light, and the transmission should also be in the N gear when the car is being towed. 4. D Gear is the Driving Gear: When the gear lever is in the D position, the gears inside the transmission automatically switch between the lowest and highest gears according to the set shifting rules, based on factors such as vehicle speed and throttle opening. In most cases, you can drive using the D gear.

Are Automatic Transmissions Prone to Failure?

Automatic transmissions do not easily fail during daily use. Here are some relevant details: 1. The internal structure of an automatic transmission is relatively more complex compared to a manual transmission, which means it requires more attention to maintenance during daily use. The primary aspects of maintaining an automatic transmission include ensuring the quality of the lubricating oil and avoiding operation under overload conditions to prevent overheating and aging of internal components. Due to its complex structure, transmission fluid plays an even more critical role. 2. In daily vehicle use, most automatic transmission failures stem from issues with the transmission fluid. Besides lubrication and cooling, automatic transmission fluid also assists in power transfer. If the fluid is not replaced for extended periods, impurities and sludge can accumulate, reducing its lubrication effectiveness and increasing wear on components like gears.

What to Do When Mercedes-Benz Seat Adjustment Fails?

Reasons for Mercedes-Benz seat adjustment failure: 1. Electric seat jamming or seizing up. The seat adjustment linkage needs lubrication. 2. Wiring issues. Check the fuse first, then inspect if the seat motor is functioning properly. 3. Adjustment linkage or slide rails are blocked or lack lubrication. Automotive seats should meet the following requirements: 1. The arrangement of seats within the entire cabin should be reasonable, especially the driver's seat must be in the optimal position. 2. The seat's design must comply with human physiological functions, ensuring comfort while striving for aesthetics. 3. Seats must be safe and reliable, with sufficient strength, stiffness, and durability, featuring a compact structure and minimizing weight as much as possible. 4. Various adjustment mechanisms designed for passenger comfort must have reliable locking devices to ensure safety.

Can a sedan be equipped with a roof rack?

Sedans can be equipped with roof racks. The installation method for roof racks is as follows: 1. Choose a suitable roof rack; 2. Thoroughly clean the roof surface. If there are no pre-installed screws on the roof, adhesive-type roof racks can be installed; 3. Find symmetrical and suitable positions, ensuring balance both front-to-back and side-to-side; 4. Slowly peel off the adhesive backing of the roof rack, stick it to the roof, and press firmly for more than 10 minutes to allow the adhesive to bond properly. Precautions for using roof racks include: 1. Ensure cargo is tightly secured or properly fixed on the rack and evenly distributed; 2. Use non-elastic ropes to tie down the luggage; 3. Pay special attention when carrying large items on the roof rack.
