Seven ways to get the most from your gearbox
Gears make the world go round – well not quite but they do turn a vehicle’s wheels. And when they fail, there’s not much that much that you can do other than call a recovery company. The best bet is to ensure your gearbox lasts and keeps you running on the road. Here are our top driving tips to keep your gearbox in tip-top shape. 


Use straight lines and 90 degrees angles
The best way to maintain your gearbox from inside the car is to go back to basics when you were learning to drive. Be gentle and use straight lines and 90 degree angles when changing gear in a manual vehicle to avoid damage to the hatchings or going into the wrong gear and overworking the engine. 


Rev matching
The key thing to do is to ensure you have the right level of revs for the gear you are changing up from and the gear you are changing into. Maximising the potential of the vehicle’s torque curve through rev matching will go a long way to avoiding gearbox gremlins when out on the road. 


Be in the right gear at the right time

The aim of the game is to maximise your driven wheel force at any one time. To do this the key equation is: Maximum wheel torque = Engine torque x Gear ratio. All this is to say, the gear ratio you’re in and engine torque combined is key to the drive of the wheels, meaning having the car in the right gear with the right rev level is key to efficient driving. 


Be smooth, don’t overwork specific parts of the car
Smooth driving in all aspects will always be beneficial. While we all need to rush at times, aggressive driving will always reduce the lifespan of the engine, tyres and especially the gearbox and transmission, as the higher rev levels force more power than is ideal through the gearbox. 


Turn later in corner and glide through apex

Once again, smoothness is key. Cutting apexes on the road may be the shortest route but turning in later to the corner enables you to glide through the corner and avoid unnecessary gear changes. 


Prepare for what’s in front of you

Be prepared, anticipating what you are about to have to do on the road gives you more time to react, allowing you to take more time changing gear and go through processes like rev matching, rather than slamming on the brakes and changing gears urgently, potentially putting too much energy through the gearbox due to a sudden change in workload. 


Skip gears where necessary
Depending on the conditions and circumstances, block shifting could be the way to go. While in normal driving conditions, block shifting up is unlikely to match the torque curves of the two gears, as the skipped gear will have the desired gear ratio. Block shifting under braking or deceleration is far more useful to reduce the number of gear changes approaching junctions and increasing the lifespan of the gearbox. 


There are lots of little things you can do to maintain gearbox reliability. However, it is always worth servicing every 20 000 miles to identify any issues.
