The gear should remain at D position. Changing gear frequently from D to N and back will cause more wear to the valves and clutch plates.
It is not advisable to shift to N while on the move as this may damage the internal parts of the device. When engaged at N, deceleration will allow the output shaft to overrun the hydraulic clutches and the gear trains of the gearbox. All hydraulic clutches at this gear will be at a disengaged position. The driving and driven plates will be separated slightly as they rub against one another, causing premature wear and tear. At D position, the governor or speeds sensor in the Electronic Control Transmission is still in operation. There will then be an automatic downshift, also known as coast downshift, to give better control of the vehicle and engine braking.
You can shift gears according to the road condition. For normal in-town and highway driving, use D4. The car will start with first gear and shift automatically to second, third and fourth. Use D3 when driving in heavy traffic. Use D2 for increase engine brake when driving down hill or for increase engine power when driving up hill. Use the first gear to provide maximum engine braking effect or when driving down a steep gradient. For more details, refer to your vehicle owner’s manual.
It means that when the vehicle attempts to move from a stop position, the vehicle barely moves or does not move at all.
Overdrives are usually set to function at speeds above 60 km/h to reduce engine Revolution Per Minute under lighter operating conditions. Pressing the button will de-select the overdrive mode,OD sign lights up i.e. No OD. The OD function is equivalent to the fifth gear in a manual gearbox, which is used for long distance cruising for the benefit of fuel economy as well as minimising engine wear and tear. For example, you may de-select OD when going uphill to give more torque and engine braking.
Transmission fluid change is necessary to remove the accumulated dirt and particles in the fluid. Otherwise, these will reduce the fluid effectiveness and result in more wear and tear on the transmission. As a guide, the automatic transmission fluid and the filter should be checked and if necessary changed every 20,000km or every six months. This is applicable to Singapore conditions of city driving and hot weather throughout the year.
It should be bright cherry red.
No! Loss of any fluid will affect the performance of the transmission. Call us for assistance.
The scanner will communicate with the computer in your car to determine if any trouble code is present. Scanners become very important in the diagnosis of health of the transmission in today’s market.
