Manual transmissions are slowly getting replaced by Automated Manual Transmissions (AMT) or Continuously Variable Transmission (CVT), but still most of the car we use daily are equipped with manual transmission. Here we have compiled 3 things that you should not do with a manual transmission vehicle. There are lots of things happening under your dashboard till engine compartment when you shift the gear and you may not fully understand how things work and that’s the reason we are here to help you to understand why you should not do them.
1. Resting Hand on the Gear knob
First of all, Gear-knob is not a hand rest. Do the gearshift and put your hand back on the wheel or on the armrest, but Gear-knob is not your hand rest. So why you should not rest your hand on the gear knob, to have the answer you need to understand what’s happening behind the dashboard. When you shift gears, you have a selector fork and while switching gear you push selector fork against the rotating collar by pressing the collar to the gear you want to choose. The gap between selector fork and rotating collar is kept minimum to have quick and efficient shifts, but by holding a gear knob you might be putting a pressure on selector fork to get into friction on the rotating collar. Its not a huge deal, but you should know that putting a pressure on gear knob might cause wear and tear of the selector fork and rotating collar which eventually put a hole in the driver’s pocket. You can also find a note regarding same in your car manual that says,
DO NOT USE GEARSHIFT AS HANDREST, THIS CAN RESULT PREMATURE WEAR OF TRANSAXLE FORKS,
2. Leaving Vehicle in Gear at the Red Signal Light
When you are at signal and the vehicle is completely at the halt, its the best way to put in neutral because, if you leave in the gear the engine is already engaged in the transmission and there is a small amount of wear and tear goes around the clutch plates and the pressure plate. To have longer life of your vehicle transmission its always a good practice to put the vehicle in neutral and if the signal is for a long time say more than 120 seconds, its the best idea to switch off the engine.
3. Never use a clutch to hold the vehicle against Hill
When you are at the hill and stuck in traffic, it’s common practice to hold the vehicle by achieving the sweet spot between half clutch and the gentle throttle. But at that time you are burning the friction material that is mainly used to engage and disengage the gearbox and the engine.(refer Image above). Depending on accelerator position the engine is running at different speeds and the gearbox is stationary, when half clutch is pressed, the engine is running at higher speed and the contact between gearbox and engine is not complete. The partial contact makes the clutch plate wear at a faster rate than regular full engaged position. Try using hand brake in such situations than the half clutch.
