The transmission oil filler port for the Haval H7 is located at the bottom of the transmission. Hazards of not changing transmission oil: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage of the transmission valve body. Transmission oil is different from engine oil. Although both oils serve a lubricating function, they have different effects and should not be confused. Differences: Engine oil is a lubricant for the engine system, possessing certain properties such as oxidation resistance, wear resistance, and corrosion prevention. Transmission oil, on the other hand, is mainly used to keep the gear system clean and extend the service life of internal transmission components. Because the structure and operating environment of the transmission and the engine are different, transmission oil cannot be used as engine oil, nor can engine oil be used as transmission oil.

Last time I helped my colleague add transmission fluid to his Haval H7, it took some time to locate the filler port. After opening the hood, look carefully at the left side of the engine compartment towards the transmission housing - you'll find a round plastic cap, possibly marked with ATF, which is the filler port. You'll need a special wrench to unscrew the cap - don't apply excessive force to avoid damaging the threads. I recommend first cleaning the surrounding area with a cloth before pouring new fluid, otherwise contaminants could enter and damage internal transmission components. Add the fluid slowly in small increments to ensure proper fluid level - both overfilling and underfilling will affect shift smoothness. If unsure about the location, check the owner's manual for diagrams or take a photo to confirm with a repair shop. Regular transmission fluid changes significantly extend service life - never neglect this maintenance.

Is it necessary to shift to N gear when having Auto Hold?

Cars equipped with the Auto Hold function do not require shifting to N gear during temporary stops. Auto Hold is essentially an automatic braking feature. When waiting at traffic lights, there is no need to engage the handbrake or electronic parking brake, and consequently, there's no need to change gears. However, in situations of severe traffic congestion where the vehicle remains stationary for extended periods, it is advisable to deactivate the Auto Hold function and switch to manual control by shifting to neutral (N gear). This practice helps protect the transmission and engine, thereby extending their service life. The English term for Auto Hold is 'AutoHold,' and its button is typically marked with a capital letter 'A' or the full English spelling. It relies on an intelligent braking system to function.

Matching RPM and Gears in Manual Transmission?

Manual transmission vehicles require proper gear-speed synchronization as follows: 1st gear at 15 km/h; 2nd gear at 25 km/h; 3rd gear at 35 km/h; 4th gear at 55 km/h; 5th gear at 65 km/h or above. Manual transmission, also called manual gearbox, represents a fundamental type of automotive transmission system. Its primary function is to alter the gear ratio (also known as the torque ratio) by utilizing larger-diameter low-gear wheels based on the lever principle's torque mechanism, thereby amplifying engine torque to initiate vehicle movement. A manual transmission consists of three core components: the gear mechanism, transmission housing, and shift linkage assembly.
