Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
When the transmission jerks between gears or the transmission is shifting hard, it should be taken as a warning that your transmission needs repair. When a transmission is shifting hard or slipping it's time for an inspection.
A Transmission Fault
Shifting issues can sometimes cause your vehicle to feel like it is jerking when accelerating. If you have internal transmission damage, it can cause the gears to slip [and] engage over and over again, which feels like jerking when accelerating.
This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
Clogged Fuel Injectors
If you hear your car engine stuttering, then the injectors may not be providing an adequate amount of fuel. To fix this, you should clean the injectors on a regular basis. Using a fuel injector cleaning solution might eliminate the issue of the car jerking.
Dirty Air Filters
The air filter functions to prevent dirt and debris in the air from entering the engine. If it's dirty, it could restrict airflow to the engine, thus reducing the amount of oxygen that the engine gets. This causes an uneven oxygen-to-fuel ratio in the engine which leads to misfiring and car jerking.
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There's no harm in changing your fluid early.
Judder is a phenomenon wherein friction induced torsional vibrations are generated in the driveline because of sliding contact between clutch and flywheel, during engagement. These resulting oscillations inherit the first resonance frequency of the driveline.
You usually notice your car shuddering because it feels like it's vibrating. Your car will vibrate even when you're not going very fast. The shuddering makes the car lag and is very noticeable. Some vehicles have a transmission temperature indicator that will let you know when your car's transmission is overheating.
If you notice that your car jerks while you're accelerating, this is an issue that you shouldn't ignore. A jerking car is often a sign that your car will develop other problems if you don't address this issue. Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky.
A car that surges or jerks at high speed is potentially dangerous, especially in heavy traffic or in bad weather. If your vehicle jerks at high speed, you should stop driving it and have it inspected by a mechanic.
Grinding, Jerking, or Shaking
Shaking and jerking are good indicators of transmission trouble. Gear grinding is a common symptom in manual transmission vehicles. Automatic transmission failure often begins with some hesitation during gears shifting. Some might describe this a “slipping,” as well.
The short answer to this question is no, you should not drive with a bad transmission. Sometimes, life happens, and you have to keep driving your vehicle even though you know that it needs to be serviced.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
When your car jerks, stumbles or stutters while driving, it usually means something is interfering with the proper distribution and transfer of power from your transmission. Another example is if you're driving a manual transmission and haven't gained the feel of shifting for your particular vehicle.
If the air/fuel mixture inside the engine becomes too rich, it can disrupt the exhaust, causing car jerks or the accelerator to respond when you press the gas pedal. Other symptoms of a faulty catalytic converter include foul odors and decreased fuel economy.
If you're driving at freeway speeds and notice your engine sputter or jerk, you may have a failing fuel pump. This problem is caused when the fuel pump can't deliver a smooth flow of fuel to the engine; periodically, your engine receives only air when it was expecting to receive fuel.
Dirty or low oil levels can cause your car to jerk or hesitate while driving. This is because the engine is not getting the lubrication it needs to operate smoothly. If you notice your car jerking or hesitating while driving, it is important to get it checked by a mechanic.
Difficulty Shifting Gears - If you ever accelerate and hear your engine rev, but don't feel your car go any faster, your transmission is likely stuck in gear. Drivers with a manual transmission will feel some resistance when you try to shift. Not being able to shift is a direct result of having low transmission fluid.
There's a good chance you'll see drips on the ground, potentially from a leaking seal or transmission cooler hose, or it could be from damage to the case itself. In most newer vehicles with an OBDII diagnostic system, the Check Engine Light will come on when the fluid is sufficiently low.
To put it briefly, no you should never drive your vehicle if you believe there to be an issue with your transmission in any case. Once a transmission starts slipping it needs to immediately be repaired. Every time you drive it after you feel your transmission slip, it is a risk.
