Hello. From what you describe it would appear that your vehicle is experiencing some sort of power loss or acceleration issues. This can be caused by many reasons. Issues with the fuel, ignition, or engine management systems can all cause the vehicle to experience issues such as power loss and stalling. It could also be possible that the issue is clutch related. A worn or slipping clutch may not be able to hold engine torque properly, which can produce symptoms similar to those you are experiencing. If the the check engine light has come on, then retrieving the trouble codes will likely shed some light on what the issue could be. As these sorts of issues can sometimes be difficult to diagnose, if you are unsure, a professional technician, such as one from YourMechanic, can visit your location to diagnose what the exact issue may be.

Lack of response. You might notice that, while driving, your car hesitates or refuses to go into gear. This is a clear-cut sign of a problem with your transmission. This problem is usually caused by a bad clutch that needs to be replaced, but it may also be caused by a more severe problem.
The main reason the car won`t go into gear is that the level of transmission fluid in the vehicle is lower than required. If the level is low despite regular maintenance, there may be a leak. Transmission fluid, therefore, is important to ensure that the car`s moving parts are properly lubricated for functioning.
The number one cause is the clutch components have worn out and no longer have enough friction material to overcome the weight of the vehicle. A second possibility is the transmission can be stuck in two gears at the same time and it won`t move. The shift mechanism can malfunction and keep you from selecting a gear.
Just as you learned what happens with low transmission fluid, dirty fluid, or a clogged filter can cause similar transmission troubles and create a car that won`t back up in reverse. Improper lubrication from old fluid or debris in contaminated fluid will affect how the transmission shifts into reverse or other gear.
If your Volkswagen isn`t getting the proper air-to-fuel ratio, it will have trouble accelerating. Oxygen Sensor Malfunction: The oxygen sensor monitors the exhaust emissions. It analyzes the air/fuel ratio that is going through the engine. This oxygen sensor transmits the data to the computer.
The causes of this issue could range from a faulty clutch, or damaged shift linkage, to low transmission fluid levels. It could also be due to a misaligned clutch cable or the need for a clutch adjustment. A failing transmission control unit or a damaged shift fork could also cause this problem.
Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.
Worn Transmission Fluid
Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.
Why does my car not accelerate when I push the gas? A car not accelerating properly can be caused by a number of things. It could be due to the throttle body, gas tank, spark plugs, or the ECU. It could also be because you have a dirty air filter or a clogged fuel filter.
You will feel a loss in power while accelerating and at times intermittent jerks. To solve this issue find the fuel filter located in the engine bay or near the fuel tank in your car`s trunk. If the fuel filter is clogged replace it if you have the skills to do so or get it changed at your local mechanic shop.
The car can feel sluggish and heavy when there is a clogged air filter, a dirty fuel injector, or a problem with the oxygen sensor. A catalytic converter that is going bad can also make the car feel sluggish and heavy. The spark plugs may also be worn out or damaged, causing the car to lack power.
Transmission Gear Ratios
Without a transmission, once you reach your engine`s redline, that would be it, no more acceleration; you top out speed-wise. Add another gear to your transmission and you can engage it and keep accelerating, or maintain your current speed at a lower and more efficient RPM.
If you are experiencing any of these issues, it could mean that your clutch is going out: Squeaking or unusual grumbling noise when pressure is applied. Difficulty changing gears. The clutch pedal feels sticky, is vibrating or appearing to feel spongey or loose.
Typically, there are a few common causes for hard shifting in vehicles. Oftentimes, hard shifting can occur when you fail to change transmission fluid at the recommended interval. In the event that your transmission fluid gets low or dirty, your vehicle`s ability to shift could become compromised.
The brake light switch is the main culprit for your gearshift being stuck in the mode. It`s a small sensor located on the brake pedal that prevents the car from starting if the brake pedal isn`t depressed.
One of the most common reasons for poor acceleration is a problem with your car`s air intake system. If there is something blocking the air flow into your engine, it will prevent your car from getting the oxygen it needs to create the combustion needed for acceleration.
There are a few things that could cause a delay in acceleration: Fuel filters have not been replaced in awhile. Clogged or Dirty air filter. Throttle body needs cleaning.
When a throttle body is not functioning correctly, you`ll usually notice a distinctly poor or very low idle. If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed.
Driving your car through a low transmission fluid level is dangerous to you and the vehicle. Failure to top up the fluid is a hazard that might cause extreme damage to the transmission, the engine, and essential components that keep the car running.
How long can a car run without transmission fluid is up to about 10 miles on low to no transmission fluid, but doing so would be extremely risky. Transmission fluid is essential for helping your car shift gears smoothly. Without it, gears are exposed to added friction and may not be able to move at all.
A hole or a clog in the exhaust pipes can slow acceleration and make the car feel sluggish. Also, a malfunction such as oxygen sensors and the catalytic convertor could cause the car to feel sluggish.
If the main symptom you`ve noticed is difficulty changing gears, then this could also be due to a faulty gearbox. To check whether the clutch or the gearbox is to blame, turn off the engine and try changing gears. If you can then the issue often lies with the clutch.
Exactly how long they last depend on driving conditions, whether you`re towing heavy loads and even outside temperatures. That said, with normal driving you could get as little as 5-7 years out of a gearbox/transmission, or it could last the lifespan of your vehicle depending on the maintenance.
