What is the cause of the transmission module failure in the new Focus?

The cause of the transmission module failure in the new Focus is an error in the car's automatic transmission control module. 1. Analysis: A fault in the transmission control module (TCM) indicates an issue with the valve body, which can be resolved by cleaning the filter screen. Transmission fluid is a lubricant that keeps the gear system clean, ensuring the transmission operates properly and extending the lifespan of the transmission components. 2. Principle: Using liquid instead of air as the medium for transmitting kinetic energy, the pump wheel drives the turbine to rotate through the liquid, with the addition of a guide wheel between the pump wheel and turbine to improve the efficiency of liquid transmission. Since the torque converter's automatic transmission range is not wide enough and its efficiency is relatively low, changing the gear ratio expands the range of torque and speed changes in the drive wheels to adapt to frequently changing driving conditions.

What Causes the Clicking Sound from Car Tires?

In most cases, this sound is caused by small stones stuck in the tire tread. Here are some relevant explanations: 1. Small stones colliding and rubbing against the road surface can increase tire noise, producing a "click-click-click" sound. 2. Some sharp stones may puncture the outer rubber layer of the tire if lodged deeply. If they penetrate the inner tire, it can lead to air leakage, and in severe cases, damage to the steel belts, potentially causing a blowout. Therefore, it's important to promptly remove any stones stuck in the tire. 3. For minor cases with few stones, you can use a screwdriver to pry them out from the tread grooves yourself. If there are many stones, during maintenance at a 4S shop or repair shop, you can ask the technician to deflate the tire and tap it to dislodge the stones. For larger stones that remain stuck, gently remove them with a screwdriver.

Where is the production date located on Michelin tires?

The production date is marked on the sidewall of Michelin tires. Here are the relevant details: 1. Each tire's sidewall displays a string of characters containing basic tire information. 2. Different segments of this character string have different meanings - typically the last four digits indicate the production date. The first two digits represent the production week, while the last two indicate the production year. For example, 3513 means the tire was produced in the 35th week of 2013. 3. Tires generally have a shelf life of 5 years. When replacing tires, the production date should not exceed 3 years (the more recent the production date, the better, as this allows longer usage within the shelf life). However, tires only display the production date rather than indicating when the shelf life expires.
