The automatic transmission is intended to make driving easy. But it is also a very complicated mechanical system. It must be maintained with proper driving practices.
Many transmission issues aren’t due to a manufacturing fault. But rather normal but harmful driving habits.
Knowing what to avoid can keep your car in good shape. You also get to save money on maintenance.
Shifting into “park” before stopping completely
Some drivers start shifting to “Park” while the car is still moving slightly. Even slow rolling movement puts stress on the small metal gearbox locking device known as the parking pawl.
Repeated use of the transmission to stop the vehicle is harmful. It can damage internal parts over time. This can, in turn, cause major issues with the gearbox. Eventually, you might require advanced automatic transmission repair services to ensure smooth operation.
You should always bring the vehicle to a complete stop before shifting into “Park” or changing between drive modes.
Coasting in neutral to conserve fuel
Some drivers keep the transmission in “Neutral” while traveling down a hill. They assume it will help them get better fuel mileage. The reality is that today’s vehicles have been designed to do a better job of controlling fuel economy in “Drive.”
When a vehicle is coasting in neutral, it means that the driver has less control. It can affect how well the transmission oil lubricates the bearings in some transmissions. It can also cause unnecessary wear. In critical circumstances, it can cause delayed acceleration response.
The modern automatic has been designed to function efficiently. Coasting is not necessary.
Skipping transmission fluid maintenance
Transmission fluid is important for:
-
Cooling
-
Lubricating
-
Regulating hydraulic pressure.
Many drivers think that their automatic transmissions run fine until the fluid has degraded.
Dirty or burnt fluid is dangerous. It increases friction and heat within the gearbox. This leads to:
-
Clutch wear
-
Slipping
-
Rough shifting over time.
Regular fluid changes are crucial. They ensure long-term transmission reliability.
Aggressive acceleration and sudden braking
A gearbox is subjected to increased pressure and temperature when it is under constant aggressive driving. This habit is particularly dangerous when combined with the stress of repeated stop-and-go driving in heavy urban traffic.
Aggressive acceleration may result in:
-
Premature rough shifting
-
Slow gear shifting
-
Overheating.
Towing beyond vehicle capacity
Many drivers do not know the stress that towing puts on an automatic transmission. You should not exceed the manufacturer’s recommended load limit. This causes excessive heat buildup and internal wear.
This is a common problem in commercial and freight transport vehicles. In most cases, they usually transport heavy goods for longer distances. Under full load conditions, transmission failure can occur prematurely.
Always check towing limits. In addition, ensure adequate transmission cooling when towing.
Resting your hand on the gear selector
It may sound harmless. But applying constant pressure to the gear selector is not right. It can cause undue wear to the shift linkage parts over time. Some drivers also move from one drive mode to another unnecessarily during brief traffic stops.
Modern automatic transmissions are built to stay in “Drive” mode for short periods during traffic stops. There is no need for repeated manual shifts.
The last word
Better driving habits make for more reliable vehicles, lower repair bills, and longer transmission system service life.
