How to Deal with Automatic Transmission Not Shifting Gears?
2 Answers
It is normal for the gear shift to be slow during rapid acceleration to increase torque. Below is an introduction to automatic transmission: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient it is. 2. Driving Techniques: For manual transmission vehicles, it is advisable to shift gears at high RPM. The engine is designed to operate at higher RPMs, and parameters such as dynamic balance and rotational inertia of various components are also designed with high RPMs in mind. If the engine operates for a long time under abnormal conditions, the load and wear on internal components naturally increase, leading to frequent occurrences of shaking and knocking, which can also affect the engine's lifespan. Choosing 3000 RPM as the shift point ensures that the engine operates within a healthy RPM range, with the RPM dropping to around 2300 after shifting.
I've encountered the issue of my automatic transmission not shifting gears several times, likely due to insufficient or dirty transmission fluid causing increased resistance. The solution is to first slow down and stop in a safe place, turn off the engine for a few minutes to let the system cool down; then check the dipstick to see if the fluid level is within the normal range. If it's low, add the specific transmission fluid and keep the fluid clean. Restart the engine and gently press the accelerator to see if normal gear shifting resumes. If the problem persists, it could be a sensor malfunction or mechanical issue. It's advisable not to attempt repairs yourself to avoid further damage. Once, I stubbornly kept driving and ended up with severe wear, costing a lot to replace parts. Normally, drive with gentle acceleration, avoid overloading or prolonged uphill driving to reduce transmission stress. A comprehensive inspection at a professional shop is the safest approach.
