Sometimes your car will leak fluid from the transmission. This might be one of the serious problems because if it doesn’t get sorted out you could have a problem shifting gears. Irregular shifting could destroy the gearbox because the incorrect gear could be engaged during the wrong speed. For example, if you are driving fast on a highway and your car changes to the first gear, you could break the teeth because it cannot handle that speed. The first gear is always bigger in diameter because of the force required to do the initial movement.
The transmission can also experience oil leakage. This fluid looks red. It comes from the filler tube base that is located between the engine and transmission, the drain hole, the selector shaft, or the radiator. No oil leakage is good as it means that there is a hole somewhere allowing air to move into the car. Oil is also the source of lubrication inside the engine and keeps the mechanisms cool.
The filter could get clogged at any time. The filter inside the car keeps the oil clean keeping any dust or particles out of the engine. Oil supplies the car with lubrication so that there is no friction. Friction is what causes overheating and worn out parts. If you are experiencing delayed shifting and oil leaking it is likely that the filter has been clogged. This filter also keeps the dust away from the gearbox whilst it shifts. If you experience delayed shifting it could mean that there is something blocking the system from making smooth motions.
Shifting gears incorrectly can be easily felt. It often sounds like the engine is groaning if it has gone up one gear too many. This will lead to a slow pulling motion which will not allow the car to move faster until it regains its speed again.
