Sticky Shifter Issues

1. Dirt and debris:

Dirt in the shift mechanism can cause a sticky shifter

 

Accumulation of dirt, dust, or debris in the shift mechanism can cause the shifter to feel sticky or difficult to move. Regular cleaning and maintenance can help prevent this issue.

Here is what you need to do to clean the shift mechanism:

Prepare the necessary tools and materials: You will need a soft-bristle brush (such as a toothbrush), compressed air (optional), a clean microfiber cloth, and a mild cleaning solution (e.g., water with a small amount of dish soap).

Locate the shift mechanism: The shift mechanism is typically located at the base of the gear shifter, beneath the center console or on the transmission itself. Refer to your car's manual or consult a professional if you are unsure.

Remove any loose debris: Use compressed air or the soft-bristle brush to gently dislodge and remove any loose dirt, dust, or debris from the shift mechanism. Be careful not to apply excessive force to avoid damaging any components.

Dampen the cloth: Moisten the microfiber cloth with the mild cleaning solution. Ensure it is not soaking wet, as excess moisture can cause electrical or mechanical issues.

Clean the shift mechanism: Gently wipe the shift mechanism with a damp cloth, paying attention to the areas where dirt and grime have accumulated. Use small, controlled movements to avoid accidentally activating any switches or buttons.

Dry and reassemble: Once the shift mechanism is clean, use a dry microfiber cloth to remove any remaining moisture. Make sure the components are completely dry before reassembling the center console or covering the transmission.

Test the shifting: After reassembly, test the shifting to ensure smooth operation. If the stickiness persists, there may be underlying issues that require professional attention.

*Note: Remember to refer to your car's manual for any specific instructions or precautions related to cleaning the shift mechanism. If you are unsure or uncomfortable performing the cleaning yourself, it's always best to consult a professional mechanic or technician.

2. Worn shift cable:

Your shift cable or shift selector cable, puts your vehicle into the proper gear. Over time, shift cables can wear out or become stretched, leading to improper shifting and a sticky shifter. If you have an automatic transmission, then you will probably have one cable that runs from your transmission to the shifter assembly. If your vehicle is a manual, then you will have two cables.

The following video talks about 4 symptoms of a bad or stretched shift cable. Read on to learn the most common signs that your shift cable is worn.

 

If you have a sticky shifter, your car may start in the wrong gear.

 

The most common signs that your shift cable is failing include:

  • The indicator light doesn't match the gear that you are in. For example, when you move the gear stick from park to drive, the light may indicate that you are still in park.

  • Your vehicle won't turn off. If your cable has stretched then you may not be able to turn off your car as it won't go into park for you.

  • Your vehicle starts in another gear other than park or neutral.

  • Your vehicle won't shift into gear after you start it.

  • Damaged or frayed shift cables may need to be replaced.

If you have a sticky shifter and you think that your shift cables are damaged, take your vehicle to a mechanic you trust to have a look at it.

3. Low transmission fluid:

Insufficient transmission fluid levels can cause friction and resistance in the shifting mechanism, resulting in a sticky shifter. Checking and maintaining the proper transmission fluid level is crucial. Watch the following video to learn how to check your transmission fluid, or read on to follow the steps.

 

You could get a sticky shifter if your transmission fluid levels are low.

 

How to check your transmission fluid: If you don't know how to check your transmission fluid, here are the steps to follow:

Park on a level surface: Ensure your vehicle is parked on a level surface and the engine is turned off. Engage the parking brake for safety.

Locate the transmission dipstick: Open the hood of your car and locate the transmission dipstick. It is usually labelled and can be found near the back of the engine, connected to the transmission.

Identify the transmission fluid dipstick: Differentiating the transmission dipstick from other dipsticks (such as the oil dipstick) is crucial. The transmission dipstick typically has a distinct colour and is labelled as "Transmission" or "ATF" (Automatic Transmission Fluid).

Remove the dipstick: Carefully pull out the dipstick from its tube. Wipe it clean with a lint-free cloth or paper towel to remove any existing fluid.

Inspect the fluid level: Reinsert the dipstick fully into the tube and then remove it again. Look at the markings on the dipstick to determine the fluid level. There may be two sets of markings indicating "Hot" and "Cold" levels. Ensure the fluid level falls within the recommended range.

Check the fluid condition:

Observe the colour and consistency of the fluid on the dipstick. Transmission fluid should typically be transparent, reddish, or pinkish in colour. If the fluid appears dirty, dark or has a burnt smell, it may be an indication of potential issues and may require further inspection or a fluid change.

Add fluid if necessary: If the fluid level is below the recommended range, you may need to add transmission fluid. Consult your vehicle's manual to determine the correct type and amount of fluid to use. Ensure you pour the fluid through the appropriate fill hole or use a funnel if required.

Recheck the fluid level: After adding fluid, repeat steps 4 and 5 to verify that the fluid level is within the acceptable range.

Replace the dipstick: Once you have completed the check and any necessary additions, securely reinsert the dipstick back into the tube.

*Note: It's important to note that some vehicles may have different procedures or require specific steps. Always refer to your car's manual for accurate instructions and guidelines regarding transmission fluid checks.

Also, some modern vehicles have a sealed-for-life transmission that never needs to be checked, so these vehicles don’t have a dipstick. Refer to your owner’s manual to double check if this is what your car has.

If you are unsure or uncomfortable performing this task, it's recommended to seek assistance from a qualified mechanic.

4. Clutch problems:

Both manual and automatic vehicles have a clutch. The clutch engages your transmission to channel the engine's power and move your car's wheels. It also disengages the transmission to stop the wheels even when your engine is running. Watch the following video to learn more about how a clutch works.

 

If you have a sticky shifter, your clutch may be worn out.

 

For manual transmission cars, a worn-out or improperly adjusted clutch can lead to difficulty shifting and a sticky shifter. If you find that your clutch pedal is really hard to push down, then this could be a sign that your clutch is sticking. This situation is often due to an issue with the hydraulic clutch linkage.

Another indication that there is a problem with your clutch is if you push down on your clutch just a bit and it disengages immediately. A healthy clutch will need to be pushed down a few inches before it disengages.

Clutch-related issues should be diagnosed and repaired by a professional.

5. Damaged or worn shifter components:

The gear shifter in your vehicle provides you with a way to change the direction of the transmission in an automatic car. In addition, it is a safety feature that will stop the shifter from getting accidentally bumped into gear which could damage your transmission. The following video explains how a shifter works.

 

If your gear shifter is faulty, you may need to get it repaired.

 

The shifter assembly itself can develop problems, such as worn bushings or damaged internal components. In such cases, replacing or repairing the faulty parts may be necessary. Take your vehicle to a mechanic you can trust to do this repair.

6. Transmission issues:

A transmission is a crucial component in a vehicle that transfers power from the engine to the wheels. It allows the engine to operate efficiently across a range of speeds. Inside the transmission, there are gears that can be engaged or disengaged to control the vehicle's speed. The following video explains how a manual transmission works.

 

If you are having problems with your transmission, your shifter may stick.

 

When the driver shifts gears, the transmission uses a series of gears and shafts to connect the engine's power to the wheels.

Manual Transmissions: In a manual transmission, the driver operates a clutch pedal to disengage the engine from the transmission, allowing the gears to be shifted manually.

Automatic Transmissions: In an automatic transmission, the process is automated using a hydraulic system that senses the vehicle's speed and adjusts the gears accordingly.

Transmission Gears: The gears in the transmission have different sizes, which determines the gear ratio. Lower gears provide more power and acceleration, while higher gears offer higher speeds and better fuel efficiency. As the vehicle's speed changes, the transmission shifts gears to maintain optimal engine performance.

Other Transmission Components: The transmission also contains other components like a torque converter (in automatic transmissions) or a clutch (in manual transmissions) that help transfer power smoothly. Overall, the transmission plays a critical role in delivering the engine's power to the wheels, allowing the vehicle to move efficiently at different speeds.

In some cases, a sticky shifter can indicate underlying problems with your transmission, such as worn synchronizers or damaged gears. It is important to have the transmission inspected by a qualified mechanic if this is suspected.

Remember, if you are experiencing persistent issues with your car's shifter, it is recommended that you consult a certified mechanic or technician who can diagnose the specific problem and provide the appropriate solution.
