What is the fuel consumption of the transmission?
2 Answers
An automobile transmission requires approximately 4 liters of oil. The following are the functions of the transmission: 1. Change the transmission ratio: Expand the range of torque and speed changes of the driving wheels. 2. Reverse driving: Enable the car to drive in reverse while maintaining the same rotation direction of the engine. 3. Change speed: The transmission, also known as the gearbox, is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the transmission ratio between the output shaft and the input shaft in different gears. Here are some extended maintenance tips for the transmission: 1. Check oil quality and quantity: Inspect the oil quality and quantity according to the intervals specified by the manufacturer. 2. Replace oil: Regularly replace the oil with products that meet the manufacturer's specifications. 3. Transmission repair: Have the transmission serviced at a professional repair facility.
The transmission itself doesn't consume fuel, but its type and maintenance affect overall fuel consumption. Having driven for over 20 years, I've found manual transmissions give me more flexible gear control – keeping RPM low on highways does reduce fuel consumption, and in city traffic jams, it can save about 10%. Automatic transmissions are convenient, but older models with sluggish shifting tend to have higher fuel consumption; modern CVTs and dual-clutch transmissions can intelligently adjust to keep the engine operating optimally, making their fuel efficiency comparable to manuals. Degraded transmission fluid increases resistance and requires regular replacement, otherwise fuel consumption may rise by 5-10%. Driving habits also matter – aggressive throttle inputs that trigger rapid transmission responses consume more fuel. I recommend owners check fluids annually and consider newer transmission models for both fuel economy and environmental benefits.
