Symptoms of a faulty transmission output speed sensor are numerous. Below is a detailed introduction to the symptoms when the transmission output speed sensor malfunctions: 1. Automatic gear disengagement: Due to the axial force generated on the tooth surfaces of the meshing sliding gears or coupling sleeves during power transmission exceeding the locking force, the gears are automatically pushed from the meshing state to the neutral position. This can be caused by component wear and housing deformation generating axial force, insufficient gear meshing length, or failure of the self-locking mechanism—resulting in reduced locking force. 2. Other faults: Gear misalignment, where excessive clearance in parts related to the gear lever leads to inaccurate gear positioning. Lever vibration, which reflects radial or axial oscillation of the transmission gears on the gear lever. Difficulty in shifting, caused by the failure of synchronizer synchronizing elements or locking elements. Excessive gear meshing clearance, housing deformation causing impact, bearing damage, or insufficient and incorrect specification of lubricating oil.

Should You Shift to P or N Gear When Waiting at a Red Light?

When waiting at a red light, you should shift to N gear, which is the neutral gear. In this gear, the car's engine and transmission are completely disconnected. This gear is used for temporary stops (such as at a red light). To prevent the car from rolling on a slope, you must keep your foot on the brake. Automatic transmission vehicles also have P, D, R, S, and L gears: P stands for Parking gear; D stands for Drive gear; R stands for Reverse gear; S stands for Sport gear; L stands for Low gear. The advantage of an automatic transmission over a manual one is that it does not require shifting gears while driving, making it easier to operate. There are three types of car transmissions: manual transmission, automatic transmission, and semi-automatic transmission.

Can I still use a temporary license plate if I already have a regular one?

No, you cannot use a temporary license plate if you already have a regular one. Once you receive your regular license plate, the temporary plate becomes invalid. For new vehicles, after obtaining the regular license plate, the temporary plate will expire regardless of its original expiration date. Failure to display the newly issued license plate promptly may result in a 12-point deduction on your driver's license. A temporary license plate, also known as a temporary vehicle movement permit, is a paper license issued by the vehicle management department of the public security authorities for newly purchased vehicles before official registration. The validity period of a temporary license plate does not exceed 30 days, and there are four types: temporary plates for administrative jurisdictions, cross-jurisdictional temporary plates, temporary plates for testing purposes, and temporary plates for special-type motor vehicles.

Does Carlife Support Amap Navigation?

Carlife does not support Amap navigation. It is a new type of car networking system launched by Baidu, which can achieve real-time interconnection between mobile phones and cars. Unlike Apple's plug-and-play, Baidu Carlife requires a separate client download. After connecting via USB, the client needs to be launched, and the mobile phone must not be in the lock screen state. Car-phone interconnection mapping projects the phone screen onto the car display, allowing operations such as navigation, videos, music, and games on the phone through the display. The addition of the car-phone mapping function makes it convenient to watch videos from the phone on the car's large screen and use the navigation on the phone.
