It is important to bring the vehicle in as soon as possible whenever you notice an issue. This can range from low tires, leaking fluids, or even an issue from under the hood. This can include the battery, alternator, or transmission.
The transmission is designed to have two purposes. It should keep the vehicle stationary when it is required and also provide added speed when desired. A transmission works by using a clutch and gear system to get your vehicle from the park position to the speed you need or want. The clutch is what puts the vehicle into the proper gear position. It also allows the gears to operate to give the vehicle extra torque and horsepower that may be need.
If you notice that the vehicle has a delay when you shift, it could mean there is an issue with the transmission. This can be noticed from shifting the vehicle from part to reverse or drive. This is because the teeth in the gears of your transmission are not engaging properly due to a dirty gear. It could also mean the teeth have been damaged. If it is a dirty gear, it could be something as simple as doing a transmission fluid flush and it will work itself out over time. If you there are damaged teeth, you are better off replacing the whole transmission rather than the gear itself. The reason for this is that if one gear is damaged, the rest will become damaged eventually.
You might also feel like the vehicle is hitting a large bump every time the transmission goes into a higher gear. Just like having a delay in shifting from park to reverse or drive, the culprit may be a dirty gear or damaged teeth on a gear. It also could be a failing clutch. When the transmission is shifting this hard, the gears are literally slamming into place to provide the torque and horsepower your vehicle is asking for. Having this happen just one time can cause major damage to the entire system. Other gears that may not have been damaged will become damaged. It could be the teeth on a gear getting shredded, or one of those gears to completely crack. If the vehicle exhibits any of these signs, make sure to bring it in as soon as you can so we can inspect the transmission for you.
