Here are six common mistakes drivers make while driving vehicles equipped with an automatic transmission

Coasting in Neutral

Shifting an automatic transmission into neutral while on a downhill may be an old fuel-saving trick but this habit takes the control of vehicle speed out of your control except for slowing it down.

It also limits the oil supply, so the automatic transmission does not get proper lubrication for smooth operation. Which can result in significant wear and damage. RDG recommends forgetting this habit as the fuel savings negligible. Your gearbox will thank you later!

Revving the engine before shifting to drive

We all did it as teenagers launching our cars from a standstill, but doing this can cause massive shock to the gearbox leading to more friction between the internal components leading to clutch failure. It also causes serious harm to the bands and clutches of the automatic transmission.

Changing gear position while the car is moving

Shifting to drive whilst the car is still reversing makes your automatic transmission components change direction rapidly, putting premature wear on your gearbox. Always use your brakes and come to a complete stop before changing gear.

The same goes for shifting into park while the car is moving always let your car come to a stop and fully depress your brakes before shifting into park.

Shifting into neutral at traffic lights

Some people shift their automatic transmissions into neutral at traffic lights rather than keeping their foot on the brakes but it’s far safer and better for your transmission to leave it in drive.

Cars with Automatic transmissions are made to save fuel while the car is in drive so the old way of thinking leaving your car in neutral while stopped to save fuel no longer applies. This coupled with not being able to react quickly in an emergency situation if your vehicle is in neutral means there is no benefit at all to leaving your vehicle in neutral while waiting for the lights to change

Keep your fuel levels in check

Automatic transmissions in cars depend on proper lubrication and require adequate fluid pressure to operate properly. Petrol helps keep your vehicles engine and other components lubricated and cool.

So while petrol may be more and more expensive letting your tank run near empty repeatedly may end up costing more than a top up ever will.

Driving your car hard while your automatic transmission is still cold

Whether you are late for work, frustrated and wanting to get out on the road or just want to drive a little like a race car driver it’s always essential to allow your cars automatic transmission to warm up properly before driving it hard.

This is especially important in the winter months while it’s cold outside as oil is generally thicker while it’s cold. Giving your car some time to warm up and allowing lubricant to properly get around your engine and transmission before driving it hard is essential to avoid damaging your engine or gearbox.
