Not Stopping Before Switching From Reverse to Drive
Depending on where you're driving, this can also pose a safety risk. This maneuver puts unnecessary pressure on your transmission. No matter if you're driving or reversing first, always brake before switching gears.
Risks damage to the transmission
Another way that driving fast can damage your car is by damaging the transmission. When you drive too fast, you are putting a lot of strain on the gears. This can cause the gears to strip and eventually break.
Time and mileage vary between car drivers and how they use or abuse their transmissions. Still, typical automatic transmissions last around 150,00 to 200,000 miles or approximately 7 years. Cases exist in both extremes; extreme longevity and early failure.
With proper maintenance, transmissions can last up to 300,000 miles or more. This includes changing the fluid in your transmission system and regular checkups. However, when you don't keep up with routine maintenance, your transmission might have problems at the 100,000-mile mark or even sooner.
Transmission failure can result from transmission overload when the transmission is forced to shift gears too rapidly. Transmission overload can be caused by sudden acceleration, driving up steep hills, or driving with a full vehicle when the load is much lighter than normal.
Luckily, transmission failure doesn't usually happen without warning. There are several warning signs that your transmission's going out.
Bad habits such as parking without the handbrake, changing gears incorrectly, and shifting an automatic transmission before the car comes to a complete stop can cause your transmission to wear out prematurely.
Transmission repair is ideal for minor fixes. This type of repair can include fixing specific components, in-car repairs, various adjustments, and resealing jobs. Transmission repairs do not require the transmission to be rebuilt completely. This type of repair is not an option for transmissions with extensive damages.
Without service and maintenance, some transmissions can fail in as little as 100,000 miles. If you drive around 10-15,000 miles a year, your transmission could be down for the count in seven years! With care and service, transmissions can last 300,000 miles or more.
Standard transmissions usually don't need to be replaced during their entire lifetime, whereas some automatic transmissions need replacing around the 200-250,000 km mark. Overall, it is important to maintain regular servicing and maintenance for your transmission.
Park the vehicle, set the parking brake, then step on the clutch pedal, and put the transmission into first gear. Listen and feel for any grinding, or other noises when putting the shifter into gear, as that could indicate a potential problem with that particular gears' synchronizer.
Typically, when your transmission begins to fail you may start to notice some form of difficulty when changing gears. Occasionally you may hear or feel a clunk noise when you shift gear. Another sign of a rough shifting is difficulty in accelerating to the speed for the gear that it is in.
Transmission Repairs
Often with a transmission repair, you are only fixing one specific part of the transmission. This repair can take place without having to rebuild the entire transmission. This option typically costs less than a rebuild or a replacement.
Modifying the factory gear ratios in stock transmissions can improve a car's speed because less torque is transferred to the drive wheels.
Using a freewheel may reduce shift time, as it may not be necessary to use the clutch. A shift kit is also intended to reduce the shift time of a manual vehicle. With a manual transmission, upshift time can be reduced by installing a lighter flywheel.
Manual transmissions require less servicing to remain functional and don't need the same type of oil as an automatic transmission. Cars with a stick-shift usually last longer than an automatic of the same make and model.
