Is the Transmission Oil the Same as the Rear Axle Oil?

1 Answers

Transmission oil and rear axle oil are different. When replacing transmission oil, it is necessary to use dedicated transmission oil and not substitute it with other fluids. Transmission oil is crucial for the transmission system as it serves functions such as power transmission, heat dissipation, lubrication, and rust prevention. More details are as follows: 1. There are two types of car transmissions: automatic transmissions and manual transmissions. 2. There are three common types of automatic transmissions in cars: AT transmissions, dual-clutch transmissions, and CVT transmissions. 3. Dual-clutch transmission: This is a product developed based on manual transmissions. Its structure is similar to that of a manual transmission, with the addition of an extra clutch and a set of gear-shifting control mechanisms. One clutch controls the odd-numbered gears, while the other controls the even-numbered gears. Dual-clutch transmissions offer fast gear-shifting speeds and relatively high transmission efficiency. 4. CVT transmission: This is a relatively simple automatic transmission with only two cone wheels and a steel belt inside. The steel belt can move on the cone wheels, allowing the transmission to change speed and torque. CVT transmissions are compact, lightweight, and relatively low-cost.

How to Conduct the Annual Inspection for a Seven-Year-Old Vehicle?

The vehicle owner should prepare the necessary documents, including ID card, driver's license, and other required materials, then drive the vehicle to a nearby inspection station. Wait for the inspection. The inspector will first check the vehicle's exterior and engine, then drive the vehicle onto the testing line for an emissions check. After completing the first four steps, wait for the online inspection. Once the inspection is passed, pay the fee and collect the inspection compliance sticker.

What are the automatic transmission gears of the Qoros 5?

The Qoros 5 automatic transmission features P, R, N, D, and M gears. The P gear is the parking gear, used after the vehicle is parked; the R gear is the reverse gear, utilized when reversing, with safety precautions necessary during operation; the N gear is the neutral gear, which disconnects the engine's power; the D gear is the drive gear for normal forward movement; and the M gear is the manual mode, allowing the driver to manually control gear shifts. In addition to these standard automatic transmission gears, some models may include S and L gears. The S gear is the sport mode, differing from the D gear only in that the computer switches to a different shifting program. The S gear can be engaged at any time without risking damage to the transmission, making it suitable for overtaking and climbing hills, though it is not recommended for other scenarios due to higher fuel consumption. The L gear is the low gear, used to reduce brake usage when descending hills and to provide more power when ascending. Furthermore, some vehicles may subdivide the D gear into D1, D2, and D3. D1 locks the gear in first, overriding automatic control. D2 locks the gear in second, allowing shifts between first and second but not exceeding second gear. D3 locks the gear in third, permitting automatic shifts among first, second, and third gears but not beyond third gear.

How to Operate the Rearview Mirror Button?

Adjust the left and right positions so that the left edge of the mirror just cuts off the right ear of your reflection in the mirror. When adjusting the up and down positions, place the distant horizon in the center, and adjust the left and right positions so that the car body occupies 1/4 of the mirror's area. For the right rearview mirror, adjust the up and down positions to occupy about 2/3 of the mirror. Adjust the left and right positions so that the car body occupies 1/4 of the mirror's area.

What Are the Standard Dimensions of a Sedan?

Standard sedan dimensions are categorized into several levels. For family cars, the length typically ranges from 3800mm to 4300mm, width from 1600mm to 1800mm, and height from 1400mm to 1600mm. 1. Length: Length is the most influential parameter affecting a car's purpose, functionality, and ease of use. Therefore, vehicle classes are generally divided based on length. A longer body means more longitudinal usable space, which is obvious; however, an excessively long body can make turning and parking inconvenient. 2. Width: Width mainly affects passenger space and maneuverability. For passenger sedans, if three seats arranged side by side are required to provide a spacious feel (primarily sufficient shoulder room), the width generally needs to reach 1.8 meters. In recent years, due to increased safety requirements, the thickness of door panels has increased, leading to a general increase in vehicle width. 3. Height: Vehicle height directly impacts the center of gravity (handling) and interior space. Most sedans have a height below 1.5 meters, significantly lower than the natural sitting height of a human, primarily to lower the vehicle's center of gravity and ensure stability during high-speed turns to prevent rollovers. 4. Wheelbase: Once the vehicle length is determined, the wheelbase becomes the most critical factor affecting passenger space, as the majority of two-box and three-box sedans position passenger seats between the front and rear axles. A longer wheelbase increases longitudinal space for passengers, directly benefiting legroom, which significantly impacts ride comfort.

Why does the new battery lose power when accelerating?

Here are the reasons why the new battery loses power when accelerating: 1. High starting current: The current is about three times that of normal driving. The combined resistance of the wiring, internal resistance of the battery, and the controller's field-effect transistors, along with high-current discharge, causes significant voltage fluctuations. 2. Charging duration: Battery self-discharge. Some users do not ride their electric vehicles immediately after fully charging them, leaving the vehicle unused for several days without timely recharging. 3. Damp wiring: If the electric vehicle is frequently used in rainy or snowy weather, damp wiring could also be a possible reason.

What are the steps for starting a car for the first time?

First, check around the car for any obstacles and inspect the tire pressure. Ensure safety before opening the door and entering the vehicle. Next, check the dashboard. Then, from left to right, inspect the left rearview mirror, and of course, also glance at the dashboard to check the fuel level and whether the headlights are on. After that, fasten the seatbelt, turn on the left turn signal, press down the clutch, shift into first gear, release the handbrake, and then slowly release the clutch to start the car while ensuring safety.
