Car Jerks Forward When Driving: Transmission Problems

If your car is jerking forward when driving, it could be a sign of a transmission problem. Here are some of the most common causes:

1. Low Transmission Fluid

Low transmission fluid is one of the most common causes of transmission problems. When the fluid level is low, the transmission can’t properly lubricate its components, which can lead to jerking, slipping, and other problems.

Symptoms of low transmission fluid:

• Jerking or slipping when shifting gears
• Difficulty shifting gears
• Transmission fluid leak

How to fix low transmission fluid:

1. Check the transmission fluid level and add fluid as needed.
2. If there is a leak, fix it as soon as possible.

2. Dirty Transmission Fluid

Dirty transmission fluid can also cause transmission problems. When the fluid is dirty, it can clog the transmission filter and restrict the flow of fluid. This can lead to jerking, slipping, and other problems.

Symptoms of dirty transmission fluid:

• Jerking or slipping when shifting gears
• Difficulty shifting gears
• Dark or dirty transmission fluid

How to fix dirty transmission fluid:

1. Flush the transmission fluid.
2. Replace the transmission filter.

3. Worn Transmission Components

Worn transmission components can also cause transmission problems. When components are worn, they can’t properly engage with each other, which can lead to jerking, slipping, and other problems.

Symptoms of worn transmission components:

• Jerking or slipping when shifting gears
• Difficulty shifting gears
• Grinding or whining noises when shifting gears

How to fix worn transmission components:

1. Replace the worn components.

4. Faulty Transmission Solenoids

Faulty transmission solenoids can also cause transmission problems. Solenoids are electrical components that control the flow of fluid in the transmission. When solenoids are faulty, they can cause the transmission to shift gears erratically, which can lead to jerking.

Symptoms of faulty transmission solenoids:

• Jerking or slipping when shifting gears
• Difficulty shifting gears
• Check engine light

How to fix faulty transmission solenoids:

1. Replace the faulty solenoids.

5. Faulty Transmission Control Module

The transmission control module (TCM) is a computer that controls the transmission. When the TCM is faulty, it can cause the transmission to shift gears erratically, which can lead to jerking.

Symptoms of a faulty transmission control module:

• Jerking or slipping when shifting gears
• Difficulty shifting gears
• Check engine light

How to fix a faulty transmission control module:

1. Replace the faulty TCM.

Conclusion

If your car is jerking forward when driving, it could be a sign of a transmission problem. The best way to diagnose the problem is to take your car to a qualified mechanic. The mechanic will be able to inspect the transmission and determine the cause of the problem.
