What Are the Causes of High Transmission Temperature?

What does the P gear mean?

The P gear stands for Parking gear, which is used when the vehicle is parked. It is the most common gear in automatic transmission vehicles, usually located at the frontmost position of the gear shift console, ahead of the R gear. Its principle is to lock the vehicle using an internal mechanism in the transmission. When you reach your destination or need to park for an extended period, shift the gear lever into this position. Note: The vehicle must come to a complete stop before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can cause mechanical damage to the automatic transmission. When P gear is engaged, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, it is essential to engage P gear when parking on an inclined road. Additionally, during short stops (e.g., at traffic lights), it is best not to shift into P gear to avoid severe damage to the entire transmission in case of a rear-end collision. Apart from this, manual transmission vehicles have numerical gears such as 1, 2, 3, 4, and 5, while automatic transmission vehicles have letter gears like P, N, D, S, M, and L. Introduction to manual transmission numerical gears: First gear is the starting gear, used when the vehicle begins moving from a standstill. Another meaning of the starting gear is that it is only used for starting; once the vehicle starts moving, it should be shifted to second gear. Second gear is the driving gear, used when the vehicle is moving at low speeds. It is not meant for high-speed driving. Third gear is the acceleration gear, where you can start using the throttle to accelerate and increase the vehicle's speed. Fourth gear is the medium-high-speed driving gear, typically used in urban roads (excluding elevated roads), with speeds generally maintained around 60-70 km/h. Fifth gear is the high-speed gear, used only on elevated roads or highways, usually at speeds of 80 km/h or above. Introduction to automatic transmission letter gears: N gear: Neutral, also called the neutral gear. At traffic lights, you can shift into this gear and press the brake pedal. If the wait is longer, it is advisable to engage the handbrake, allowing your foot to rest off the brake pedal. A common misconception is that shifting into N gear while coasting downhill or at high speeds saves fuel. This is a serious mistake—it not only does not save fuel but can also damage the transmission. D gear: Drive, meaning the forward gear. Shifting into this gear and pressing the accelerator allows the vehicle to move. In this gear, the transmission automatically shifts based on speed and throttle input. At traffic lights, you can stay in D gear while pressing the brake. For short waits, this is fine, but prolonged stops can raise transmission oil temperature and degrade the oil. S gear: Sport, meaning the sport mode. In this gear, the transmission delays shifting to provide more power, usually used when overtaking. M gear: Manual, meaning the manual mode. Similar to manual transmission vehicles, it requires manual gear shifting. L gear: Low, meaning the low-speed forward gear. In this gear, the transmission operates only in the lowest gear (equivalent to first gear in manual transmissions) and does not automatically shift based on speed. This gear is typically used when climbing or descending steep slopes. In low gear, the drive wheels deliver higher torque, ensuring sufficient power for climbing steep slopes. Prolonged braking can overheat the brake pads, reducing braking efficiency, which is dangerous on long or steep descents. Shifting into L gear uses the engine's low RPM to control the vehicle's movement, eliminating the need for constant braking.

What does it mean when the ABS light on the car dashboard is on?

When the ABS light is displayed on the car, it indicates a fault in the vehicle's anti-lock braking system. If the wheels lock up during emergency braking, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. There are various states in which the ABS light may illuminate, and the causes and solutions differ depending on the state. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed or the wheel's slip rate, thus failing to issue the appropriate commands to regulate braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Inspect the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and the voltage rises, the ABS indicator turns off. This may also be due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains on after engine startup and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; loose wiring connections in the ABS hydraulic valve body; ABS computer malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, and clean the contact surface if necessary. Check for enlarged gaps in the connectors. Replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also be due to incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, and manually push the brake switch lever down to its limit. Release the brake pedal to complete the self-setting process. Replace the brake light switch if necessary.

How to Use Gears on Uphill Roads?

When going uphill, you should not suddenly accelerate rapidly. Instead, maintain a steady speed to climb the slope smoothly. When climbing a hill, you must use first or second gear. Be careful not to shift gears while climbing, as this can easily cause the engine to stall.

How Do Insurance Companies Handle Water-Damaged Vehicles?

Insurance company staff will arrive at the scene to take photos of the water-damaged vehicle for damage assessment, which facilitates subsequent insurance claims. The insurance company will contact a towing company to transport the vehicle to an auto repair shop for handling. If losses occur due to unclear judgment of water depth, except for engine damage caused by secondary forced starting, the vehicle damage insurance will in principle cover other losses.
