Haval H6 transmission oil temperature generally should not exceed 120°C, with 80°C or 90°C being the optimal range. Prolonged exposure to temperatures above this range will accelerate the degradation of transmission oil components and reduce its usability. At the normal operating temperature of 80°C, every 10°C increase in temperature will halve the service life of the automatic transmission oil. The hazards of excessively high transmission oil temperature are as follows: 1. High temperatures can degrade the quality and frictional characteristics of automatic transmission oil, increasing friction and wear, leading to transmission noise. Additionally, sludge (impurities or contaminants) may form inside the transmission (e.g., in the valve body), causing jerking or impact during gear shifts. 2. If the temperature exceeds 120°C, rubber sealing materials will begin to harden and age, leading to leaks due to poor sealing and ultimately resulting in reduced hydraulic pressure. If the temperature rises even higher, the transmission may start to slip, and this slippage can, in turn, cause the temperature to rise further.

I think the transmission oil temperature of the Haval H6 is normal between 85 and 95 degrees Celsius. The oil temperature should be maintained within this range under the working load of the transmission while driving. If it's too high, such as exceeding 100 degrees, it may cause the oil quality to deteriorate and accelerate the wear of internal components. On the other hand, if it's too low, such as below 70 degrees when starting a cold engine, the lubrication effect may be insufficient, affecting smooth gear shifting. During daily driving, it's important to avoid prolonged uphill climbs or towing heavy loads, as these can easily raise the oil temperature. Additionally, regularly checking the condition of the transmission oil and adhering to the replacement schedule is crucial. The Haval H6 owner's manual will provide specific recommendations. Ensuring the proper transmission oil level can help maintain stable temperature control. If abnormal oil temperature is noticed, it's best to visit a 4S dealership to check if there's an issue with the cooling system, which can prevent costly major repairs.

From my experience driving the Haval H6, the transmission oil temperature typically stays between 85 to 90 degrees Celsius under normal conditions, which is quite stable during city commutes without overheating. When driving on highways or uphill, the temperature might rise slightly to around 93 or 95 degrees, but it remains within the safe range. Remember, excessively high temperatures can damage the fluid and cause premature aging of the transmission, so I frequently monitor it via the dashboard or a mobile app. If the temperature approaches 100 degrees, I slow down to let the vehicle cool off. When changing transmission oil, it's important to choose a reputable brand, and regular maintenance helps keep the temperature within reasonable limits. The Haval H6 is well-designed, so there's generally no need to worry about oil temperature issues unless you frequently carry heavy loads or have modified the vehicle.

The transmission oil temperature of the Haval H6 should be between 80 and 100 degrees Celsius during normal driving, depending on your driving style. When starting a cold engine, the oil temperature is low, around 60 degrees, and gradually rises. Aggressive driving may briefly exceed 100 degrees but quickly drops back. Excessively high oil temperatures can shorten the oil's service life and, in severe cases, trigger a fault warning light, so maintaining balanced driving is crucial. Regular oil changes and checking oil levels can help maintain proper temperature control. The Haval series has reasonable oil temperature settings, making it easy for beginners to handle.
