By following the procedure described in this article, you may be able to repair an automatic transmission that is slipping. “Slipping” is the term applied to a transmission that doesn’t shift gears at the proper time. The condition is identified by a lag in upshifting as engine speed increases.

It is important to note that the repair is actually the severe service maintenance procedure suggested by vehicle manufacturers to prevent slippage from occurring in the first place. Manufacturers claim that performing this service every 25,000 miles, if you operate your vehicle under severe driving conditions, will prevent failure of an automatic transmission. Severe driving conditions are the following:
A transmission stays in a designated gear until a shift is performed by the driver (manual) or the computer (automatic). If yours is spontaneously slipping in and out of gear (or simply popping into neutral) while driving, I don’t need to tell you that this is a serious safety risk. One of the most common and simplest causes of a transmission slip is when there is low automatic transmission fluid. Another cause is when the transmission band is worn out or broken. With this type of problem, you will not only have to deal with the transmission slipping but a multitude of engine troubles, including worn out transmission gears. A common vehicle mechanical problem is a slipping, or improperly engaging, automatic transmission. A slipping transmission occurs when a transmission's gear sets fail to engage or synchronize properly. This significantly reduces the ability to drive the vehicle and can lead to premature automatic transmission. If your car’s automatic transmission is showing signs of slipping, then you should have it checked right away. What might seem to be a minor annoyance can turn into a bigger, more expensive problem down the road. Transmission slipping does not always mean your transmission is going to fail, but it is a signal that maintenance is required.
- Operating a vehicle primarily in stop-and-go city traffic most of the time.
- Operating a vehicle more than half the time in stop-and-go city traffic when the ambient temperature is 90°F or higher.
- Using a vehicle to tow a trailer.
- Driving a vehicle primarily in a dusty environment.
- Driving a vehicle primarily over hills or mountains.
These severe driving conditions cause fluid in an automatic transmission to overheat and become contaminated. The fluid then loses its ability to protect delicate parts of a transmission, which will sustain damage.
Periodically draining and examining automatic transmission fluid in a vehicle used under one or more severe conditions will allow you to detect the onset of trouble. Professional transmission repair services can fix it for you with ease. If failure has already occurred and a transmission is slipping, replacing the fluid could also resolve the problem.
Whether you are attempting to repair an automatic transmission that is slipping or have decided to implement a maintenance program to ward off trouble, the following describes what to do. Suppose, however, the problem you’re having is not a slipping transmission, but a fluid leak from around the transmission pan. The same instructions can be followed to repair the leak.
- Drive the vehicle at least 10 miles to heat the transmission fluid.
- Park the vehicle on a level surface, shut off the engine, place the transmission shift selector in Park, and engage the parking brake.
- Jack up the front of the vehicle using good quality Floor Jacks.
- Place a support stand under each front control arm and lower the vehicle onto the stands.
- Ram chocks against both sides of each rear tire to prevent the vehicle from rolling back.
- Place a large pan under the transmission pan.
- Remove the bolts by starting at a corner, so that the corner drops lower than the rest of the transmission pan, and allow fluid to flow into the other pan.
- Take out the remaining bolts and remove the transmission pan.
- Before discarding the fluid that remains in the bottom of the transmission pan, inspect it for particles, color, and odor. Slosh the fluid back and forth. The presence of fine black and/or brass residue is normal. However, if larger pieces are visible, pour the fluid containing the particles into a clean jar and take-it to a transmission specialist. The specialist will be able to determine what should be done to prevent damage from progressing to an advanced stage. Fluid should be red. If it looks muddy and/or smells like varnish, filling the transmission with fresh fluid may straighten out a slipping condition. Incidentally, if fluid is white, the transmission oil cooler has a leak that is allowing coolant to mix with transmission fluid. Take the vehicle to an auto repair shop to have the cooler replaced.
- Continue the repair by peeling or scraping off the gasket from the rim of the transmission pan and from the rim of the transmission body. All of this material must be removed or it will prevent the pan from seating securely to the transmission. This will cause a fluid leak.
- Using a nonflammable solvent, which is available from an auto supply store, wash the pan.
- Locate the transmission fluid filter inside the transmission. It is out in the open and easily reached. Remove the screw(s) that hold the filter in place and take the filter out of the transmission. If the filter is made of paper or felt, replace it. If it is made of metal, wash it in nonflammable solvent and put it back into the transmission.
- Place a new gasket on the rim of the transmission pan so that the holes in the gasket align with the holes in the rim of the pan. Make sure the gasket lies straight as you place the pan against the body of the transmission, and insert the bolts.
- When all bolts are in place, tighten a bolt using a wrench. Then, tighten the bolt that lies diagonally across from the one you just tightened. Follow this pattern to tighten all the bolts.
- Remove the automatic transmission fluid dipstick. Wipe it with a clean cloth and place it where it won’t become dirty.
- Insert a clean funnel into the dipstick tube and pour in one quart of the type of automatic transmission fluid recommended by the vehicle manufacturer. This information can be found in your owner’s manual. Use only this fluid, as any other type can cause transmission damage.
- Reinsert the dipstick and pull it out again to check the fluid level. Continue filling the transmission in this manner until the fluid level hits the FULL mark on the dipstick.
- With the dipstick seated in the dipstick tube, start the engine and let it warm up for five minutes. Then, move the transmission shift lever through all gears and back again toward Park, pausing momentarily between each shift. Keep your foot planted firmly on the brake pedal to prevent the vehicle from moving.
- With the shift lever again in Park, turn off the engine and withdraw the fluid dipstick to check the fluid level. If it has dropped below FULL, add enough fluid to bring it back to that mark or a little below. Be careful not to exceed the FULL mark. Too much fluid in an automatic transmission will cause the transmission to slip.
- Over the next few days, check the fluid level often and keep an eye on the ground where you park the vehicle. If the level drops and/or you notice fluid on the ground under where the transmission was positioned, the pan is leaking. Tighten the bolts a bit more. If the leak persists, you may have damaged the gasket and should install a new one.
Draining the transmission will not get rid of all the old fluid. Some will be trapped in the torque converter. If the torque converter in your car doesn’t have a drain plug, you will have to repeat the drainage procedure twice more after driving the vehicle in increments of 5,000 miles. There is, however, an easier solution. Have a 1/2-inch threaded drain plug installed in the transmission pan at a transmission shop.
With a drain plug in the transmission pan, drive the vehicle for 5,000 miles so that the fresh fluid you put in the transmission mixes with the old fluid trapped in the torque converter. You can then drain fluid by simply removing the drain plug.
Dealing with a slipping transmission can be a significant problem with any car; especially those with automatic transmissions. This is one of the many issues with your auto that can begin as a minor issue and then quickly worsen, becoming more expensive. You should never delay repairing a slipping transmission.
There are multiple potential slipping transmission causes, and although maintenance is always required, the severity of the problem can vary greatly. Remember that the transmission slipping indicates that you need a mechanic’s assistance, regardless of the severity.
Signs of a Slipping Transmission: What Does a Slipping Transmission Feel Like?
Automatic Transmission Slipping Gear
If you are unsure how to tell if your transmission is slipping, be on the lookout for some of the more common transmission slipping symptoms. The following are among the most common slipping transmission signs:
- Your check engine light is on
- An rpm of over 3,500
- Acceleration delays
- Burning or unusual smells
- Inability to reverse
- Problems shifting gears
- Harsh responses or strange noises when shifting gears
- The reverse does not engage
If you’re wondering what it means when your transmission is slipping or what transmission slipping is, these transmission slipping signs should give you a good idea. There is no clear definition of exactly one thing that signifies a slipping transmission, as the problem is mostly defined by its symptoms and causes. As such, your best course of action is to watch for the above signs and, if you encounter them, begin to look at your repair options.
Any of the above signs your transmission is slipping may point to a range of problems, not limited to the transmission slipping. However, they do all require maintenance, so if you notice any of those symptoms, you will want to visit your mechanic.
You should also be on the lookout for other potential signs of transmission problems, which may or may not include slipping. Your mechanic can help you with how to tell if transmission is slipping or you have another problem.
Leaking Transmission Fluid
If you notice red fluid underneath your auto, then there is likely a transmission leak from a seal, gasket, or cooler line. This is damaging for the transmission and dangerous if the fluid happens to leak onto a hot surface. You can check the transmission fluid with the dipstick. Keep in mind that some of the other fluids in the transmission must be checked by a professional.
Burning Smell
The potential burning smell is usually the result of low fluid or a fluid leak. Catching this problem early is crucial to being able to fix the transmission. Action replay dsi firmware update 1.71.
It Won’t Stay in Gear or Engage
This type of problem may indicate issues with your automatic transmission valve, the shifter cable, the shifter, or a fluid leak. You may even need to have your mechanic check your auto’s computer system to see if there are trouble codes, since the computer lets the transmission known when it should go in gear on newer autos.
No Power for the Car
When your engine runs properly but your auto has minimal or no power, it may be from the computer limiting power, internal transmission problems, or the brakes dragging from a faulty brake hose or caliper.
Shifts Miss Gears or Delay
These problems can be due to low transmission fluid, which could be from water intrusion, lack of maintenance, contamination, or a leak. If you do not take care of this problem, it can lead to overheating that causes serious internal damage. Missing gears or delayed shifting can also be due to engine problems that make the computer prevent the transmission from shifting to a higher gear.
Automatic Transmission Slipping Fluid
Odd Noises
If you hear a humming, clunking, or buzzing sound from the transmission, this usually indicates an internal problem, such as bad bearing or planetary gear damage. Buzzing might also be due to a leak causing low transmission fluid, a seal, or poor internal sealing surfaces.
Remember that anytime you are unsure of how to determine whether your transmission is slipping, you should consult your mechanic to get an evaluation as well as a fix transmission slipping cost estimate.
Slipping Transmission Causes – Why Is My Transmission Slipping?
As mentioned, there is a long list of potential reasons that your transmission is slipping. Some are more common than others, and most of these are more likely to occur in automatic transmissions.
Low Fluid
Of the various slipping transmission causes, the most common is having low fluid levels. This comes from the vast ways in which low fluid levels can negatively impact your car, from not producing enough hydraulic pressure for engaging gears to overheating.
To check whether low fluid levels are causing your problem, you can just look at the dipstick in your engine compartment. Remember that the system for the transmission is closed. As such, it should never have low levels. If there are low levels, you may be dealing with a leak.
Burnt Fluid
Sometimes, the transmission slipping is due to the fluid burning instead of being low. If the fluid is black or you notice a smell similar to burnt toast, then this is the likely culprit. Burnt fluid can happen when the transmission overheats. In this case, you will need to quickly swap out your transmission fluid. After that, you will need to have a technician inspect your transmission to ensure there is no further damage.
Clutch Problems
Both automatic and manual transmissions use clutches, and while manual transmission slipping is most likely due to clutch issues, it is also a possible cause for an automatic transmission slipping. In an automatic, the transmission and torque converter have clutch plates that can burn or become worn out due to insufficient transmission fluid.
In manuals, the clutch relies on brake pads and other friction material to grab the engine flywall, helping separate the transmission and engine as you change gears. If this material gets worn, the clutch will not fully engage or switch gears, requiring a replacement.
Wartune medusa. Worn Gears
As your car ages, your gears will begin to wear out. This is completely natural and occurs due to wear and tear. Gears can also wear out from malfunctions. If the gears are frayed or worn, they will not link together properly, leading to bumpy shifting.
Solenoid Issues
Your auto’s solenoid is an electro-hydraulic valve that is responsible for controlling fluid flow in the transmission. If this component has electronic issues or suffers damage, it will not dispense the appropriate amount of fluids, leading to issues like transmission slipping. You can use an OBD2 scanner for trouble codes to help you figure out which solenoid to replace.
Problems with the Torque Converter
The torque converter converts the engine’s power so it is torque, which is the form of power that the transmission can use. Over time, the torque converter can wear down. When functioning properly, fluid will flow through your torque converter. If the fluid does not flow properly, the transmission can misbehave in a variety of ways, including slipping.
Damage to Transmission Bands
It is also very possible for your transmission bands to become broken or worn over time, leading to the transmission slipping. The bands are responsible for connecting your automatic transmission’s gears together. You can overcome this cause by replacing or adjusting the defective band(s).
In Manuals: Grinding Gears When Shifting
If the manual transmission grinds as you shift gears, this usually indicates the clutch is not releasing, the transmission’s shift synchronizer rings are broken or worn, there is an adjustment problem, transmission fluid is low, or the shifter is worn.
In Manuals: Clutch Pedal Grabbing High or Low
Automatic Transmission Slipping In Drive
Your clutch pedal engaging extremely high or low in your manual can also be transmission-related. Grabbing high may be due to worn pressure plates, worn clutch discs, or adjustments. Grabbing low is usually due to the hydraulic or linkage system experiencing problems.
Can You Drive with a Transmission Slipping?
It is not smart or safe to drive with a slipping transmission. Similarly, you should not drive the car at any point that the transmission does not work properly; this could lead to the auto unexpectedly changing gears as you drive. You would also likely notice acceleration problems.
Transmission Slipping Fix – How to Fix a Slipping Transmission
In the case of transmission slipping due to minor problems, such as low fluid levels, ineffective or burnt fluid, or a leak in the transmission, you may be able to fix the problem yourself. Most people should be able to check the fluid themselves and many will feel comfortable changing it as well. You would likely want help from a mechanic to fix a transmission leak.
The fix becomes significantly more complicated with the other causes. If you need to adjust or replace your clutch, adjust or replace the bands, or replace the gears, you are in for a bigger repair. In this case, you will likely need to dismantle the transmission to resolve the issue. It should come as no surprise that this is not something that a novice should take on. As such, you should expect to pay a mechanic to inspect and repair the transmission.
The key here is that the solution will depend on the cause of your slipping transmission.
From Low Fluid Levels
If the problem was due to low fluid levels, check the fluid levels and top them off if necessary. Ideally, you should check the levels at least monthly. This is a very quick-fix slipping transmission solution.
From Worn out or Burnt Fluid
In this case, you need to drain and change the fluid. This is a bit messy and requires some mechanical knowledge, although many home mechanics can do it themselves.

Transmission Slipping Prevention – How to Stop Transmission from Slipping
The best way to prevent your transmission from slipping is to stay on top of regular maintenance. At the very least, follow the transmission maintenance outlined in your owner’s manual. Ideally, you should regularly check your transmission fluid. You may also want to make sure that you flush it and install a new filter every 30,000 miles, although the recommended interval for this maintenance depends on your auto.
Are Repairs the Only Option? Consider Selling Your Car
Depending on the severity of your transmission slipping problems and their causes, you may find that it is impractical to make the necessary repairs. Sometimes, they will be very expensive, especially if the transmission needs to be disassembled and assessed. In this case, you may have to deal with a situation where:
Automatic Transmission Slipping In Drive
- You cannot afford the repairs
- Your vehicle is worth less than the cost of repairs
- You do not want to pay that much for repairs on an aging car
- You do not want to pay that much for repairs on a car you were planning to replace
No matter the reasons that you do not want to proceed with repairs on your car, there are still other options available. The best choice in this scenario will likely be to sell your car.
You could try to find a private buyer who wants to buy your car with its transmission slipping, but they would likely want a discount for the price of the expected repairs. This would go against the point of selling the car instead of making the repairs in the first place.
You could also try junking the car and bringing it to a scrapyard. However, these junk yards are notorious for giving poor prices and only valuing the car based on the weight of the metal, regardless of how many functional and reusable components it has. You would also have to get the car to the scrap yard.
