What is Transmission Slipping? Causes, Symptoms, Prevention, Repair Cost


What is Transmission Slipping? There is a tendency for transmission gears to slip as a result of wear and tear. When the transmission fluid has been drained or worn out and the gears have been running hot, it is quite possible that gears will wear out over time, as well as the transmission fluid.

Slippage of gears can be caused by poor engagement or by the effects of normal wear and tear over time when the gears slip in and out of sync due to a lack of engagement.

What do you mean by Transmission Slipping?

In the event of a transmission slip in your vehicle, you will hear the engine spinning during a gear change when you try to change gears. For a moment, you may feel like you are driving over ice and it will feel like you are driving over snow.

At first glance, it might seem inconsequential and easy to dismiss as insignificant and insignificant. The problem, however, can escalate into a more serious problem if you do not maintain your transmission properly and it can become a lot worse than it is

Other Factors and Causes for Transmission Slips

It is very important to address the problem of transmission slippage as soon as possible in order to avoid major repairs. It is important that you keep an eye out for the following things:-

  • Through the transmission, power from the engine is converted into motion and the vehicle is able to move. A vehicle can be equipped with an automatic transmission as well as a manual transmission.
  • Usually, if you are driving a car with an automatic transmission, the gears will be changed for you automatically, whereas if you are driving a car with a manual transmission, you may have to change gears yourself via the gear selector.
  • There are many causes of transmission problems, but slipping transmissions are among the most common. In this article, we are going to try to explain what transmission slippage is, what the causes of it are, what signs to look for, and how to prevent it, in order to provide you with the information you need.

What actually is a Transmission in a Car?

A transmission is a part of a car that acts as a gearbox that shifts the gears while driving. This type of gear shifter and chain can be found on bicycles, and it is pretty much the same type of system that can be found on bicycles when it comes to gear shifting and chains.

For the transmission of power from the engine to the wheels, the belt system and the gears on the engine are always mounted directly on the engine in order to convert the combustion power of the engine directly into physical momentum.

As part of a typical transmission, the driver is able to control how much power is delivered to the car by adjusting the number of gears and the number of chains that run around the outside of two or more gear sets to determine how much power is delivered to the car.

What does a Car Transmission do?

The transmission’s main purpose during normal operation is to ensure that the engine turns at the correct speed for your needs. As a result, you will not have to worry about spending too much or driving too slowly.

 Additionally, it ensures that the wheels receive enough power as well as ensuring that they accelerate correctly in order to ensure that the wheels get enough power. Without a transmission, it would be impossible for any car to start and stop, making it completely unreliable as well as impossible to start.

In order to maintain a low engine RPM, or revolutions per minute, a transmission changes gears according to the speed of the car and the position of the pedals in order to keep your engine running at a low power level.

What are the reasons for transmission slipping to occur?

If your transmission slips, you may experience the following conditions:

  • Low, Burned, or worn-out transmission
  • Problems with the clutch
  • Worn or Broken transmission bands
  • Torque converter issues
  • Worn out gears
  • Problems with the Solenoid

What to look for when your transmission slips

As with most automotive problems, the earlier you deal with them, the better your chances of avoiding major repairs. Your slipping transmission will likely compound more damage the longer you delay fixing it. If you do not fix this, you will end up spending a lot of money on it in the long run.

To make sure you know when your transmission is slipping, here are the signs to look out for:-

A gear switch that has been made without authorization

It is common for your vehicle to abruptly and unexpectedly switch gears while driving when your transmission is slipping. The unauthorized switching of gears is sometimes accompanied by a pitch change or sound.

The sudden switching of gears in your car could put you at risk of a life-threatening accident. There is a possibility that your car will start shaking if it is unreliable.

Having difficulty changing gears

If your vehicle is having trouble changing gears smoothly, the transmission may be slipping, which can cause the transmission to malfunction. The sound of a thud or clunk can be heard whenever the vehicle shifts down or up in gear.

Movement is delayed when there is a delay

The fact that your car does not move for a while after you shut off the engine may be a clue that your transmission has slipped.

In the event that the vehicle is changed from ‘Park’ to ‘Drive,’ it will stay stationary for a long period of time after making the change. This is the time when the car engine revs up, but it does not move at all, so this is the time when the engine revs up.

Detection of transmission fluid leaks

There is also a possibility that they may be an issue with the transmission if you observe red fluid on the garage floor along with some of the earlier symptoms listed above, in addition to some of the symptoms previously discussed.

A slipping gearbox in your car may be to blame if you notice a delay before you notice the vehicle moving forward after you feel it slip.

When your vehicle is slipping through the gears, is it safe for you to drive?

It is not safe to drive a vehicle if the transmission slips because of a problem with the transmission. As a result of this, it is highly unlikely that the vehicle’s safety will be guaranteed. When the transmission slips into different gears without telling you, it can give you a shake or even cause severe damage to your car.

The signs and symptoms of a slipping transmission should be evaluated as soon as they are noticed by you, so do not hesitate to have your vehicle checked out immediately.

Is it Possible for a Dirty Transmission Filter to Cause Slipping of the Transmission?

The dirty transmission fluid or clogged filter of the transmission can impair the transmission fluid’s ability to flow smoothly, and as a result, the internal components of the transmission can suffer from a lack of lubrication, which can ultimately cause them to malfunction.

Transmission problems can be caused by shifting problems, grinding gears, slipping transmissions, or a variety of other common symptoms associated with the transmission.

If a Transmission Slips, How Long Can it Last before it Needs to be Replaced?

As little as 100,000 miles can pass before a transmission fails if it is not serviced and maintained. In seven years, if you drive around 10-15,000 miles a year, your transmission could be done for the count if you drive around 10-15,000 miles a year! In the right hands, transmissions can last as much as 300,000 miles or more with the right care and maintenance.

Is it a good idea to drive while the transmission is slipping?

There is a short answer to this question, and that is no. In case your transmission system is not working properly, it is not safe for you to drive your car. In the event that your car shifts unexpectedly while you are driving, you could find yourself in a potentially dangerous situation. On the road, you will have to deal with acceleration problems that you do not want to worry about while driving

What is the reason for my slipping acceleration?

The clutch in your manual transmission or automatic transmission may be worn out or it may be worn out due to years of use. These are all reasons why your transmission may be slipping. In addition to the transmission, there may be other components that need to be replaced. There is a low level of transmission fluid in the transmission.

What can be done to prevent transmission from slipping in the future?

In order to prevent transmission slippage, you need to take the following steps. However, you must be sure that the problem is not caused by leaking fluids or worn-out bands, as both can cause problems. Depending on whether this is the case, you may have to replace either the worn-out gears, the solenoids, the clutch, or the torque converter if the gears are worn out.

If a transmission specialist deals with any of these repairs for you, you will have to pay a tremendous amount of money for it, especially if it is a complex repair. In this case, having an older vehicle is not going to be in your favor, and that is why you should check out all the other options before making a final decision.

Points to remember for the prevention of transmission slipping

  • In the case of a newer vehicle, you might be able to identify the problem based on the motor’s onboard diagnostics computer. In this case, the solenoid can be the culprit behind the transmission problem if the solenoid is malfunctioning.
  • In any case, if the transmission in your newer vehicle is transmitting error codes, make sure you check them out as soon as possible in order to determine what they are telling you about the transmission’s condition.
  • Consider examining the transmission bands if you still are not able to pinpoint the root cause of the problem. It is important to replace any transmission band that has worn out or has broken. In the event that you need to replace a single band, then you should replace them all as soon as possible. The purpose of this is to avoid the need to deal with this particular issue within the next few weeks or months.
  • If you are able to get under your hood, you can also confirm the level of your transmission fluid by looking under there. It is important to ensure that the fluid level is correct at all times.
  • In the event that the transmission fluid level is lower than it should be for any given reason, you should try to identify where the leak originated from. You may discover that the seal of a fluid line is loose or that holes have been discovered in the lines as a result of the leak.
  • There is also the possibility that the transmission pan might leak, or that the transmission pan gasket may be faulty.
  • In case you are a keen DIYer, you can probably replace these faulty parts by yourself if you are experienced at doing so. It is possible, however, that if you discover a cracked torque converter and are not able to repair it on your own, you will need to hire professionals for a look-see and in-depth repair.
  • It is important to determine where the leak is coming from or the source of the leak and to fix it as soon as possible. The next time you replenish the transmission fluid, you could also consider adding an excellent leak sealing solution that you can use to seal the transmission leaks.

How Much Does It Cost To Repair A Slipping Transmission?

It can be very expensive to repair a slipping transmission in your vehicle if you are not aware of the problem from the beginning. If your transmission is slipping, you should know what is causing it to slip before making a decision about having it replaced. It will be determined during this process if it is necessary to completely replace the transmission or just make minor repairs to it.

There may be a time when you need to take your vehicle to a professional to have it repaired if it is experiencing slipping.

Average repair cost

You can expect to pay on average $2,800 for a complete transmission replacement if your vehicle’s transmission needs to be completely replaced. There is a wide range of prices for this service that can range from $1,400 to $5,800, depending on your vehicle’s year, make, and model. However, it is possible that your transmission may be able to be rebuilt for around $1400 if you are interested.

Additionally, there is a possibility that the slipping may be due to the failure of an electronic component, which would cost about $300 plus labor costs of $460 in some cases.

Cost of fixing a slipping transmission

Depending on the reason that your transmission is slipping, the cost to fix it can range from as little as $5 up to $5,800, depending on how long it takes to fix it.

A slipping transmission can be caused by a variety of things, but the following are some common causes and the cost associated with them:-

Worn out clutch

There is also a possibility that a slipping transmission could be caused by the clutch inside the transmission wearing out. In the event that the clutch on your vehicle is worn out, you will notice that it requires more effort for you to drive your car. Depending on the model of the clutch, the cost of replacing the clutch can range from $1,200 and up.

Lower Fluid

It is very common for slipping transmissions to occur when the vehicle is being driven while the fluid level is low or the vehicle is parked. The average cost of adding some transmission fluid to an automobile is approximately $8, depending on the vehicle.

The fluid that is burnt

There is also a possibility that your transmission can slip if the transmission fluid becomes burnt inside it. Under average conditions, flushing and replacement of the fluid will be required, and this will cost about $120 in total.

A worn-out gearbox

A slipping transmission can also be caused when the gears become worn down or burnt due to the excessive stress placed on them as a result of excessive use. There is a possibility that all your gears will need to be replaced if they are worn out. A gear replacement can cost anywhere between $100 and $250 per gear, depending on what type of gear is being replaced.

Failure of the Torque Converter

The torque converter inside your transmission is also susceptible to failure, which could cause your transmission to slip. Most of the time, it is possible to replace a torque converter for around $700 in most cases, so this is an average cost.

Failure of the shift solenoid

By ensuring that fluid circulates through the solenoid attached to the transmission shift knob, you are able to control how quickly the gears are shifted in your automatic transmission. In the event that this is damaged or fails, you will experience transmission slippage.

In order to replace a single shift solenoid, you should be prepared to pay a price between $150 and $500.

Replacing a Transmission

It is estimated that the cost of replacing a transmission if it has completely failed will be between $1,400 and $5,800, depending on the condition of the transmission. It will depend on where you are taking the vehicle and which kind of vehicle you are driving as to how much this will cost.

  • Occasionally, it may be necessary to replace all the parts of your old transmission with new parts, even if doing so would be more economical than replacing certain parts of your old transmission entirely.
  • As you know, your transmission is made up of a number of different parts, which are all working together as one unit, so if even one part of it is damaged, you could run into more problems in the future, which can be very costly
  • There is no doubt that the cost of a new transmission can reach as high as $5,800 or even more in some cases if it is performed by a professional.

Cost of the rebuilding a transmission

If you are looking for a longer-term solution, you may want to consider rebuilding your transmission. When compared to the cost of replacing the entire system with a new one, this is a much cheaper option.

Rebuilding a transmission can cost anywhere between $1,000 and $3,000 on average, depending on the transmission type.

What do you mean by a transmission input speed sensor?

Due to their fluid nature, torque converters, which are fluid drives, are able to cause this slipping effect due to their fluid nature. The input speed sensors detect the movement of input shafts, and these signals are transmitted to the control module by means of wires that are used to transmit them.

What causes the transmission to slip while changing from the first gear to the second gear?

Having a damaged synchronizer ring in your manual transmission will result in gear slippage in your transmission. The condition of your synchronizer ring should be checked once in a while if shifting gears becomes hard every once in a while. 

What do you mean by Lucas Transmission Fix?

The Lucas Transmission Fix removes the majority of seal leaks in worn transmissions, as well as slips, hesitations, and rough shifting caused by worn transmission seals. Any transmission should be maintained on a regular basis as a preventative measure.

Despite Lucas Transmission Fix’s additives’ ability to improve gear engagement, preventing slipping transmission leaks remains more of a hit and miss affair as it depends on the severity of the leak itself. The Lucas transmissions are one of the best choices when it comes to solving problems associated with slipping transmissions with a high mileage.

Transmission Fluid Additive to prevent Transmission Slipping

There are a few vital functions that your transmission fluid performs. This fluid performs a number of functions such as acting as a hydraulic fluid to enable shifting, preventing gears and bearings from wearing down, managing heat, and providing frictional properties to ensure smooth, consistent shifting as well.

When the transmission fluid gets extremely hot from towing or hauling, it can deteriorate over time, especially if the fluid is not changed on a regular basis.

In order to provide the correct frictional properties, as well as heat resistance and other properties and to also avoid transmission slipping, transmission fluid additives are carefully designed to restore the fluid’s original properties. There are some additives that purport to soften and swell worn seals, purportedly preventing leaks by softening and swelling them.

Best Transmission Fluid Additive

 In our opinion, the best transmission additive is the Prolong Super Lubricants PSL15000. Compared to other transmission additives on the market, this is one of the best. As a result, the amount of sludge buildup, leaks, shudders, and slippage is reduced. In case you are looking for a less expensive option, then you might want to consider the Lucas LUC10009.

Fixing for the Transmission Slipping

In the case that the slipping is going on because of ineffective fluid or a low fluid level caused by a leak, then you may be able to solve the problem by either checking and replacing the fluid or repairing/plugging the leak in order to fix the problem yourself.

When a transmission has more serious problems such as worn or broken bands, clutches, or gears, it will have to be taken apart and disassembled in order to be repaired. It is highly recommended that only those with significant experience in auto repair should attempt these procedures.

Torque converter and solenoid replacements should be left to the professionals.

The fluid level in your vehicle is low – check and top it off as soon as possible

Regularly monitoring your fluid level is one of the easiest ways to prevent problems in the future. Every month or every two weeks if you drive a lot, you should open the hood of your vehicle, locate the transmission dipstick, and check the level of the ATF under the hood. As a general rule, you should always do this while the engine is running, as in order to get an accurate reading of the internal pump, you need to have the engine running.

  • Whenever you notice that the fluid appears to be dark, thin, dirty, or if it smells burnt, you should immediately change it. To prevent further damage to the engine, if you notice that the fluid level on the dipstick is below the optimum level, add more fluid as soon as possible.
  • In order to ensure that you have the right kind of ATF in your car, check the owner’s manual to ensure that you have the right kind of fluid using the wrong type of fluid can actually cause serious damage to your vehicle.
  • When filling an automatic transmission with fluid, you place a funnel inside the dipstick tube, which is what you typically do when you add fluid. Whenever you are unsure, you are advised to refer to the instructions in your owner’s manual.

The fluid that has been burned or worn out should be drained and refilled

You are able to either change your automatic transmission fluid yourself, or you can have a repair shop do it for you if you need it done. To do it correctly, it does require some mechanical experience, as it can be a messy job and it can be a bit messy.

A shop manual is available at your local auto parts store and you can find step-by-step instructions on how to repair your vehicle. The process goes as follows:

  • Remove the pan from the vehicle by jacking it up and unbolting it. There will be a draining of ATF as you do this, so make sure you place a catch pan and a tarp underneath the tank as you proceed
  • Replace the filter by removing it and replacing it with a new one
  • You will need to scrape off the old transmission pan gasket and replace it with the new one.
  • The pan should be bolted on and ATF should be poured into it
  • Make sure that the vehicle is started and that there are no leaks
  • Clean the mess you have just created with copious amounts of kitty litter as soon as you are done making it

In the event of a fluid leak, you should replace the part(s) or get it repaired

The source of the leak in your transmission needs to be identified if your transmission is leaking fluid. If you are an experienced DIYer, you should be able to research your vehicle’s specific symptoms, replace the offending parts, and fix them on your own.

If you cannot fix the problem yourself and do not feel comfortable doing so, then you should find a mechanic right away. In any other case, that tiny transmission leak could end up creating a much bigger and more expensive problem in the future.

As a last resort, if everything else fails

A transmission repair shop is a good place to take your car if none of the solutions above work (you can use the guide below for a price guide) or if you are having trouble with your transmission and you need to replace it.

The cost of remanufactured transmissions according to the vehicle type

  • Using the Year / Make / Model lookup tool above, you are able to determine the type of transmission your vehicle is equipped with.
