The reasons why an automatic transmission spins freely without moving when shifted include: 1. Insufficient transmission fluid or low internal oil pressure; 2. Incorrect gear switch signal; 3. Issues with the shift solenoid valve wiring or the solenoid valve itself; 4. Problems with the internal actuating mechanism of the transmission. Here are the solutions: 1. Check whether the transmission has insufficient fluid, whether the main oil pressure and gear oil pressure are normal, then verify if the gear switch signal is correct, if the wiring from the transmission computer to the shift solenoid valve is intact, and if the gear solenoid valve is functioning properly. 2. If all these are normal, it indicates a problem with the internal control system of the transmission, and the transmission should be disassembled to inspect the internal actuating components.

Where is the manual transmission of the Roewe RX5 produced?

The manual transmission used in the Roewe RX5 is the SCM250 manual transmission from Shanghai Gear Works. It is the same model as that used in the MG GS and is based on technology originally from Germany's LUK company. Below are the relevant details: 1. The 1.5T and 2.0T engines in the Roewe RX5 are the same as those in the earlier-launched MG GS, and both are produced at SAIC's Lingang factory. 2. The 1.5T engine is paired with either a 6-speed manual transmission or a 7-speed dry dual-clutch transmission, while the 2.0T engine is matched with a 6-speed wet dual-clutch transmission. Apart from the manual transmission option for the 1.5T, all other transmissions are dual-clutch types. 3. Compared to automatic models, the manual transmission in the Roewe RX5 offers more direct power delivery and a more engaging driving experience. Additionally, manual transmission models are generally priced lower, making them a more economical choice for consumers.

How long will it take for the vehicle transfer to expire after successful completion?

There is no time limit for the vehicle transfer application after it is successfully completed. It should be noted that the vehicle inspection must be completed within three working days from the date of acceptance by the vehicle management office of the destination, and the application cannot be made within two years after expiration. Vehicle transfer requires the replacement of license plates and the vehicle registration certificate, and the procedures should be handled separately in two vehicle management authorities, including the procedures for transfer out and transfer in. Materials required for vehicle transfer: Identity proof of the current vehicle owner. Proof and certificate of vehicle ownership transfer. Vehicle registration certificate, vehicle license. For vehicles under customs supervision, the "Certificate of Release from Supervision of the People's Republic of China Customs" or a customs-approved transfer certificate should also be submitted. For vehicles that have exceeded the inspection validity period, the vehicle safety technical inspection qualification certificate and the compulsory traffic accident liability insurance certificate should also be submitted. Precautions before handling vehicle transfer business: If the annual inspection period is approaching, the inspection qualification mark must be applied for first before handling the transfer. The existing license plate needs to be handed over to the vehicle management office, and dismantling tools should be prepared in advance.

What is the four-wheel drive system of the Audi Q7?

Audi Q7 is equipped with Audi's unique quattro four-wheel drive system. Here are the relevant details: 1. This four-wheel drive system is used in multiple high-performance models from Audi, renowned for its excellent reputation and strong capabilities, representing a benchmark in full-time four-wheel drive. 2. This system has undergone seven generations of updates, with its core component being the famous Torsen differential. Starting from the second-generation four-wheel drive system, Audi adopted the Torsen differential, which is most notable for its torque-sensing capability. 3. Under normal driving conditions, this system distributes the vehicle's power in a 50:50 ratio between the front and rear axles. If any wheel experiences slippage during driving, the central differential optimally redistributes power to the axles. 4. This system allows completely unrestricted and flexible torque distribution between the front and rear axles, adapting to varying driving conditions and weather. During normal driving, the engine's torque is primarily delivered to the rear wheels, working in tandem with the vehicle stability system to prevent slippage or rollover, even on slippery surfaces.

What kind of glue should be used to reattach a fallen car rearview mirror?

You can use mirror base adhesive, which is a specialized glue for car glass rearview mirrors, similar to AB glue. Car rearview mirrors are located on both sides of the front of the car and inside the front of the vehicle. They reflect the situation behind, beside, and below the car, serving as the "second pair of eyes" and expanding the driver's field of vision. More relevant information is as follows: 1. If you can't manage to stick it back no matter what, you can use a suction cup rearview mirror. This type of rearview mirror doesn't require adhesive on the back; it only needs the suction cup to adhere to the glass, making it very practical and convenient. If you purchase a heavy-duty suction cup, any dashcam can be hung on it. 2. Generally, factory-installed rearview mirrors won't fall off under normal use unless heavy objects are hung on them, such as some pendants or dashcams attached to the rearview mirror. When reattaching, be sure to remove these items, and it's best to find a way not to place them on the rearview mirror.

Why is the light not on when there is power?

Possible causes of the fault include: an open circuit or grounding in the power line before the light switch; the circuit breaker tripping or burning out in the circuit; poor contact or failure to close of the bimetallic strip contacts in the light switch, or damage to the light switch itself; grounding in some part of the light circuit causing the bimetallic strip contacts to open when a certain position of the light switch is engaged. Additional troubleshooting steps are as follows: 1. Test by honking the horn or activating the signal light switch: If the horn sounds and the turn signal lights up, it indicates that the power line before the circuit breaker is functioning properly. Therefore, you can use a test light or a power short-circuit method to check for open circuits in sequence at the ammeter connection, ignition switch terminal, and light switch terminal. If the circuit connections are good, the light switch may be damaged. 2. If the horn does not sound when tested and the circuit breaker has not tripped: This indicates an open circuit or poor connection somewhere in the power line before the circuit breaker. If the circuit breaker trips, it indicates grounding somewhere in the line after the circuit breaker. You can disconnect the power lines to the horn and turn signal lights and then test by pressing the circuit breaker button again. If it does not trip again and the lights come on when the light switch is engaged, it means the grounding is in the horn or turn signal light circuit. If the circuit breaker still trips, use the power short-circuit method to locate the grounding point in sequence. 3. If the test light at the power terminal of the light switch is good: But when a certain position of the light switch is engaged, the bimetallic strip contacts frequently open and the light does not come on, this indicates grounding somewhere in the light circuit for that position. 4. When driving at night: If all the lights suddenly go out, you should stop immediately and test the horn. If the horn sounds, it indicates the power supply is still good, and you should still check the light circuit in sequence for grounding or open circuits. If the horn does not sound, it may be due to the power line coming loose or breaking from vibration while driving. First, check the battery terminals for good connection, then proceed to locate the fault in sequence.
