When you put your car in reverse, it should go backwards. But some cars can be unexpectedly put into a forward motion in the reverse gear, known as “going forward in reverse automatic”. This issue can result from wear and tear on the car’s transmission components or low transmission fluid levels. Understanding what causes this problem and how it can be fixed is important.
How Automatic Transmissions Work
In order for a car to move forward or backward, the power generated by its engine must be passed through its transmission to the wheels. An automatic transmission uses an intricate gear ratio system to send power from the engine input shaft to the wheels via an output shaft. The driver selects which gear they want their car to drive using a shifter connected to the transmission control unit (TCU). This TCU then sends signals to hydraulic solenoids, which actuate different valves that control fluid pressure and shift fork movement within the transmission’s valve body. As these parts move together, they force different gears together so that power is redirected from one side of the transaxle (output) shafts to another (input).
Why Does My Car Go Forward in Reverse Automatic?
There are a few possible reasons why your car might be going forward in reverse automatic:
Low Transmission Fluid Levels: Low transmission fluid levels can cause the transmission to slip out of gear, resulting in the car going forward in reverse gear. Check your car’s transmission fluid level and top it off if necessary.
Worn or Damaged Transmission Parts: Over time, wear and tear on the components inside of your car’s transmission can cause them to fail, resulting in your car going forwards when you expect it to go backwards. This can be due to worn bearings, gaskets or shift forks within the transmission that needs to be replaced or repaired.
Faulty Shift Solenoids: Your car’s shift solenoids control when and how much hydraulic pressure is applied inside the transmission. If these parts become damaged or faulty, they may not effectively control fluid pressure, leading to slipping gears and a car going forward in automatic reverse mode.
Malfunctioning Torque Converter: The torque converter helps transmit power from the engine’s crankshaft to its wheels by using hydraulic pressure and magnets. When these parts become worn or damaged, they can cause the transmission to slip, resulting in a car going forward in reverse automatic.
Other Possible Causes: A few other possible causes of a car going forward in reverse automatic include faulty wiring, incorrect transmission fluid type or low engine oil levels.
Signs of a Car Going Forward in Reverse Automatic
There are a few warning signs that you may experience if your car is going forward in reverse automatic: strange noises coming from the transmission, jerking or slipping when shifting gears, and excessive vibration while driving. These symptoms can be dangerous and should be addressed as soon as possible.
Is it Safe to Drive with this Issue?
No, it is not safe to drive if your car is going forward in reverse automatic because it can affect the reliability and performance of your vehicle. If you experience this issue, stop driving immediately and have it checked out by an experienced mechanic as soon as possible.
How to Fix a Car that Goes Forward in Reverse Automatic?
The best way to fix a car that goes forward in reverse automatic is by addressing the underlying cause of the problem:
Check Transmission Fluid Levels: Correct the transmission fluid level and top it off if necessary.
Repair or Replace Worn or Damaged Transmission Parts: If any parts within your transmission are worn or damaged, they should be replaced or repaired as soon as possible.
Replace Faulty Shift Solenoids: Your car’s shift solenoids may need to be replaced if they become faulty in order to ensure your car shifts properly.
Replace a Malfunctioning Torque Converter: A malfunctioning torque converter can also cause your car to go forward in reverse automatic and should be replaced if needed.
Other Possible Solutions: If none of the above fixes works, there could be other possibilities, such as faulty wiring, incorrect transmission fluid type, or low levels of engine oil, that need to be addressed by a professional mechanic.
Preventing a Car from Going Forward in Reverse Automatic
The best way to prevent a car from going forward in reverse automatic is by regularly maintaining its transmission components and ensuring all fluids are at the correct level according to your vehicle’s manufacturer specifications. It is also important to remember that even with proper maintenance, wear and tear on parts over time can lead to this issue, so be sure to have your car checked regularly to ensure everything is in good condition.
It can be concerning if your car is going forward in reverse automatic. It is important to address the issue as soon as possible by determining the underlying cause and taking appropriate action, such as replacing worn or damaged parts, adding more transmission fluid, or replacing faulty solenoids. With proper maintenance and regular checks by a professional mechanic, you can help prevent this issue from occurring in the future.
