How To Fix Slipping Transmission Quick Fix?

A slipping transmission is an issue in an automatic transmission, where the gears don’t engage correctly, causing the vehicle to lose power and the engine to run but not at speed it was intended to. The problem is usually caused by worn or damaged bands or clutch plates that stop the transmission from efficiently transferring energy from the motor to its wheels.

If you’ve got a slippy transmission, you know the frustration and dangers it could be. A slipping transmission could cause your car to slow down, jerk, or even stop, making it difficult to accelerate, keep speed, or even climb up hills. Fortunately, simple fixes and avoiding expensive fixes or repairs can resolve this issue.

How To Tell If The Automatic Transmission Is Slipping?

What Is Transmission Slipping?

Transmission slip occurs when the transmission does not engage properly, which causes an engine to crank, but not produce acceleration. This can happen when the transmission isn’t working properly, which diminishes speed and power. This issue can worsen as time passes and can eventually cause complete transmission failure.

Signs Of Transmission Slipping

Several signs could indicate a failing transmission. Here are a few of the most frequent:

  • RPMs increase; however, speed does not.

When you observe that your engine is running faster than normal, yet the speed of your vehicle isn’t growing the same way, this is a signal that your transmission may be sliding.

  • The gear shifts are sloppy or delayed.

If you notice an issue with shifting gears or the gears changes without a jolt, it could indicate slipping in the transmission.

  • Burning Smell

If you notice the smell of burning coming from the underside of your car, it could indicate a shifting transmission. The overheated transmission fluid typically causes the smell.

  • Transmission Fluid Leak

If you spot a pool of brownish-reddish fluid under your vehicle, It could indicate a leak in the transmission fluid. This can be caused by an aging or damaged seal on the transmission, leading to low transmission fluid levels and transmission slippage.

  • Check Engine Light

When the light for the check engine is on, it could be a sign that a transmission is slipping. Modern vehicles have advanced sensors that can identify problems in the transmission, which can cause an engine check light to turn on.

What Should You Do If You Think Your Transmission Is Slippage?

If you believe your transmission is failing and you suspect it’s slipping, it’s important to have it examined by a qualified mechanic. They can identify the issue and offer required repairs. A few of the most commonly-repaired fixes include changing the fluid in the transmission and the transmission filter. Also, possibly rebuilding or repairing the entire transmission.

It is essential to take care of the issue as quickly as possible, as transmission slippage could lead to complete transmission failure and require costly replacement.

Repairing A Slipping Transmission

Check The Transmission Fluid Level And Quality

The first thing to do when you observe shifting transmissions is to examine the level of transmission fluid and the quality. A dirty or low transmission fluid level could cause the bands or plates to shift, resulting in inefficient shifting or transmission failure. To determine the level of fluid, Follow these steps:

  1. Place your car on a level area and brake on your parking.
  2. Shut off the engine and wait a few minutes to let the fluid sit.
  3. Find the dipstick for the transmission (usually identified with a yellow or red handle) and remove it.
  4. Cleanse the dipstick using the help of a paper towel.
  5. Insert the dipstick all the way through and then remove it again.
  6. Verify the level of fluid against the dipstick’s marks. If it’s not at the minimum mark or adds marks, add the recommended kind of fluid (check the owner’s manual for your vehicle or the cap on your transmission fluid for the correct specifications).
  7. Examine the fluid’s quality by examining the color, smell, and consistency. The fresh transmission fluid must be reddish and should have a pleasant smell. When the transmission fluid appears dark and dirty or burnt or has a sour smell, it could indicate an issue in the transmission, like wear-out, overheated parts, or leaks.

If the fluid level or quality is poor, You should either upgrade or replace the fluid as quickly as you can. On the other hand, if the fluid is of the proper quality and level, the transmission’s slipping could be due to other causes.

Adjust The Throttle Cable Or Linkage

Another reason for an unsteady transmission could be an improperly adjusted throttle cable or linkage. If the linkage or throttle cable isn’t tight enough and the engine cannot force sufficient to the transmission, which can cause slipping or delayed shifts. To alter the linkage or cable for the throttle, the following steps must be followed:

  1. Locate the throttle cable, or linkage, connected to your accelerator or the throttle body.
  2. Examine the linkage or cable to see any indications of wear or tear, damage, or looseness.
  3. Release the locknut or adjuster on the linkage or cable.
  4. Move the linkage or cable until the engine runs well, as well as the transmission changes in the right manner.
  5. The locknut should be tightened or adjusted to ensure that the cable or linkage is to the cable or linkage.
  6. Take a test drive to ensure that the slipping has been eliminated.

If the linkage or throttle cable is damaged or worn down, replacing it may be necessary rather than making adjustments. Contact a professional mechanic or repair manual for the specifics.

Replace The Transmission Filter And Gasket

A leaky or blocked gasket or filter in the transmission could also result in slippage of the transmission. The transmission filter assists in removing dirt and particles from the fluid, and gaskets seal the pan and pan to stop fluid leaks. As time passes, the gasket and filter may become worn, dirty, or damaged, which can decrease fluid flow, pressure, and slippage. If you want to replace the gasket and filter, you must:

  1. The drain plug or pan should remove the old transmission fluid.
  2. Take off the bolts that secure the pan of transmission and filter.
  3. Remove the pan and filter, taking care not to leak any liquid.
  4. Clean the magnet and pan with a solvent and a cloth free of lint.
  5. Install the new gasket and filter following the manufacturer’s directions.
  6. Attach the pan and bolts, ensuring you tighten them to the required value.
  7. Replace the transmission’s fluid with the recommended amount and type of fluid.
  8. Start the motor and allow it to idle for a couple of minutes.
  9. Switch through all the gears and allow the transmission to warm up.
  10. Again, verify the fluid’s level and quality, and alter the level if necessary.

Removing the transmission’s gasket and filter is an unpleasant and lengthy task; however, it will significantly increase the efficiency and lifespan of your vehicle.

Add A Transmission Additive

If none of these strategies work, consider adding a transmission component to the water. An additive for transmissions is an organic compound created to improve the fluid’s cleaning, lubrication, and sealing characteristics. Certain additives claim that they can reduce wear and friction, increase performance, and prolong the life of the transmission. However, not all additives are created equal, and some could be more harmful than beneficial. So, it is important to choose a trusted brand and carefully follow its instructions. Also, be aware that adding an ingredient is not an option.

Seek Professional Help

If the solutions mentioned above cannot resolve the issue, or if the problem persists or worsens, you must seek help from an experienced technician or transmission expert. A shifting transmission that slips could indicate a more serious problem, like worn bands or plates for the clutch-damaged valve body and torque converters that are defective and internal leaks. Trying to repair or diagnose the problem without the right knowledge, tools, and equipment could be risky and expensive. A skilled technician can conduct an exhaustive inspection, determine the cause of the slip,

Adjust The Transmission Bands

If you own manual transmission or a non-electronic automated transmission, it could have adjustable transmission bands that regulate gears’ engagement and friction. With time, these bands will wear down or loosen up, which causes the transmission to slide or shift incorrectly. Adjusting the bands can be a complex process requiring special tools and experience. Therefore it’s not recommended for novice DIYers. If you understand mechanics and have access to a repair guide, you could try adjusting the bands by yourself. The most common method is to take off the valve and pan for the transmission, then the body and identify the adjustment screws, then loosen the locknuts, and then turn the adjustment screws according to the torque and clearance that you have specified. Once the bands have been adjusted, it is time to rebuild the transmission and drive the vehicle to ensure that the slipping issue has been removed. Remember that improper adjustment of the bands can cause additional issues, like jerky switching or even burning clutches. Be cautious and double-check the adjustments.

Check The Torque Converter

A torque converter can be described as a coupling device that transmits the force from the motor to the. It comprises a pump, motor, stator, and an automatic clutch. When the converter isn’t working properly, it could result in the transmission’s ability to slide or twitch, or even overheat. The most frequent issues that affect torque converters are damaged turbine blades or pumps, damaged clutches or stators fluid, contamination of the fluid, or defective solenoids. To determine the condition of the torque converter, it is necessary to conduct various diagnostic tests like stall speed tests, lock-up tests, pressure tests, and fluid analyses. These tests require specific equipment and experience. Therefore it is recommended that an experienced technician or mechanic take these tests. If the converter turns out to be inoperable, the device may have to be repaired or replaced.

In the end, fixing the problem of slipping transmissions depends on the issue’s root. A few simple fixes, like changing the filter and fluid, adding an additive, or altering the bands, could be accomplished by DIYers equipped with the proper tools and skills. However, more complicated problems, like issues with the torque converter, need specialized diagnosis and repairs that experts must handle. Nevertheless, if you can identify and address the root of the issue and cause the issue, you will save yourself time, money, headaches, and even hassles later on.

Check The Transmission Mounts And Driveshaft

Another reason for an unsteady transmission could be an aging or damaged drive shaft or transmission mount. The amount of transmission is a polyurethane or rubber cushion that helps to support and separate it from the vehicle’s chassis or frame. If the mount has become damaged or worn out, it may permit the transmission to oscillate or vibrate too much, which can cause the gears to shift or break. In the same way, the driveshaft is a unidirectional shaft that transfers energy from it to either the front or rear wheels. When the drive shaft is bent or off balance or is wearing U-joints, it may result in noise, vibrations, or even slipping. For a visual inspection of the transmission mount visual inspection, look at it for signs of cracks, tears, or sliding. To examine the driveshaft, you can inspect it with a camera, a road test, or balancing testing. If the driveshaft or the mount is found damaged, it will need to be repaired or replaced by a qualified mechanic.

Check The Electrical And Sensor Components

Modern automatic transmissions depend heavily on the sensor and electronic components that control the operation and shifting of gears. If any of the components fails or malfunctions, they could cause the transmission to slide, shift strangely or enter the limp mode. Common sensor and electrical components are:

  • The transmission control module (TCM).
  • The shift solenoids TPS.
  • The throttle (TPS).
  • The speed sensor.
  • The pressure sensor.

You’ll use a scanner tool or multimeter to test these components to identify Diagnostic Trouble Codes (DTCs) and the live data stream. Also, you must run some tests for functionality, including the TCM reset and solenoid test, the TPS calibration test, and the resistance sensor test. If the device has been found defective and needs to be replaced, it will need to be repaired or replaced by a trained technician.

Preventive Maintenance Tips

Avoiding slipping in your transmission is always more effective than fixing it. To ensure that your transmission is in good shape, it is recommended to adhere to the manufacturer’s recommended maintenance schedule and conduct regular inspections and service. Some maintenance tips that can be used to prevent problems include:

  • Monitoring the fluid’s levels and quality regularly.
  • Change the filter and fluid regularly, as recommended.
  • Making sure you are using the correct grade and type of fluid
  • Avoiding overly heavy towing or hauling or stop-and-go driving
  • Maintaining the engine’s tune-up and keeping the cooling system clean
  • Inspection and replacement of the driveshaft, transmission mount, and electrical components as required
  • Avoiding harsh shifting, over idle, or racing the engine
