What causes transmission slipping after fluid change?
One of the most essential components for a car’s regular operation is the automatic transmission. To enable the vehicle to function effectively, the component transfers power from the engine to the wheels.
The tranny lubricates a variety of moving parts, so that it aids in their smooth and unrestricted movement without causing harm to one another. When these components heat up during use, they also aid in cooling them down.
Debris will build up in the lubricant after 50,000 to 100,000 miles and impair its performance. You’ll need to change it periodically to keep the car in good shape.
However, other frequent issues include automatic transmissions that won’t shift into gear after a fluid change or slipping transmissions.
Now let’s work together to find the answer!
Signs Of Transmission Slipping After Fluid Change
Normally, swapping gears and maintaining the vehicle’s speed shouldn’t be a problem after changing the transmission fluid. Typically, neither strange noises nor hiccups occur.
However, if you observe that your car starts to shift gears erratically and a noise or pitch changes along with it.
It could be risky and unpredictable, resulting in erratic speed regulation and unexpected snags you want to avoid on the road.
The car can occasionally experience issues shifting gears, which is typically accompanied by a loud thud or clunk from the tranny.
The tranny doesn’t operate as expected to accelerate or hold speed at a given gear, hence the gears won’t function properly either.
A delay in the vehicle’s acceleration after stopping is another telltale symptom. The tranny is to blame if you notice that your car takes a while to move after shifting from stop to drive even when the engine is operating normally.
Other symptoms include a car that struggles to accelerate, loud engine rpm, rubbing or grinding noises when driving, and a car that feels sluggish or makes a humming noise after the gearbox fluid has been changed.
What Causes Transmission Slipping After Fluid Change?
We’ll go over the causes of transmission slipping after fluid replacement below.
Old Fluid Or Cheap
Use of outdated fluid might result in discoloration and varnish deposits forming inside the system. Following a fluid change, transmission issues are caused by deposits that normally float around the old fluid and do not concentrate anyplace.
Besides, because it will leave the majority of deposits behind, it is advised to avoid using cheap transmission fluid. These buildups on your filter stop transmission fluid from flowing, which raises the temperature and increases friction in the transmission’s parts.
No Filter Replacement
If you serviced the transmission without replacing the filter, it clogged and prevented the hydraulic pressure system from working. Slipping could happen as a result. When replaced, transmission filters can have poor retention and will occasionally slide out and sit on the pan’s bottom. Slipping could come from this.
Faulty Clutch
Almost all manual transmission slipping is due to the clutch. A clutch disc can last from 20,000 to 200,000 miles, depending on how you drive. This issue may irritate you if you don’t replace the fresh one.

Incorrect Seal Causes Leak
Transmission pan gasket failure can be caused by a number of different things, including a bad seal, burst fluid lines, a leak in the pan, or a crack in the torque converter.
Look for any leaks by checking the fluid level, the underside of your car near the pan, and the drive.
How To Fix A Slipping Transmission?
The majority of problems may be remedied by changing the lubricant properly, which entails performing a transmission flush after removing the old fluid, as we mentioned the potential causes of a slippage issue above.
You can alter the fluid entirely with this technique. The line that passes through the transmission should be connected to a transmission hose. To the output, connect it.
The old fluid is forced out by pouring fresh transmission fluid into the transmission. We advise against using this procedure unless the current transmission fluid is in good shape and exhibits no signs of harm.
In addition, if the filter contains fault signals, you need to pay attention to it. Lift the car and take the pan out. A catch pan and a tarp should be positioned underneath it as you do this. Remove the filter and replace it. The old transmission pan gasket should be removed and replaced. Add fluid to the pan after attaching it. Start the car and look for leaks.
One of the causes we addressed in the last section is fluid leaking. Find the cause of the leak if your transmission is dripping fluid. The majority of the time, seasoned do-it-yourselfers are able to investigate the symptoms particular to their car, swap out the broken parts, and fix the problem.
Is It Safe To Drive While Your Transmission Slips?
Driving while your tire is sliding is not advised at all. The moving parts may experience increased friction, heat, and severe wear and tear if the lubricant is burned or drained.
You might even experience an overheated car that won’t move.
Instead of spending a few hundred dollars on a few quarts of high-quality oil, you may eventually need to repair more sensitive and pricey parts from a transmission shop.
Not to mention how risky it is to drive when having such a problem. As we previously indicated, you will experience difficulties starting the car, accelerating, or shifting gears.
All of those problems will make it difficult for your car to operate and could also pose other risks, like losing control of your speed or getting into an accident.
As a result, you should take your car to a professional as soon as possible to have a check if you see any indications of slipping transmission.
How Much To Fix Transmission Slipping After Fluid Change?
It’s not terribly expensive to change the transmission fluid. For new fluid, budget $40 to $100. A filter and perhaps a new pan gasket are additional requirements. The majority of individuals, however, will find changing the old transmission fluid with the new fluid to be the most difficult step.
For this, you might need to visit a mechanic and ask them to handle the task on your behalf. Paying their hourly labor fee of between $80 and $110 will be necessary. Therefore, if you hire a professional to change your transmission fluid, you should expect to pay a minimum of $150 to $250 overall.
How Often to Change Transmission Fluid?
Depending on the make and model of the manual car, the majority of auto manufacturers advise changing your manual transmission fluid or gear oil at least every 30,000 miles or every 60,000 miles.
You should refer to your car’s manual to find the precise suggested interval. However, if you frequently subject your manual transmission to strain, the fluid may need to be changed sooner, possibly at 20,000 miles.
Driving small distances frequently in stop-and-go city traffic while hardly ever traveling on the freeway or outside of town would be stressful for a manual automobile. These brief drives make it necessary for a manual car’s gears to shift frequently, which strains the transmission.
Frequently Asked Questions
Q: Can a transmission be fixed if its slipping?
The most frequent and simplest to fix of the causes is Low Fluid Levels. You can check your own transmission fluid level and top it out as necessary if you detect your gears slipping. Be absolutely certain, though, that the transmission fluid you are using is the right kind for the design of your particular transmission.
Q: Can changing transmission fluid fix transmission problems?
Although changing your transmission fluid won’t cure mechanical issues, it will make shifts smoother and may even increase the lifespan of your transmission. Additionally, it may be an excellent idea to change the fluid more frequently even though manufacturers generally advise 150,000 miles between fluid changes under typical circumstances.
Q: Can a dirty transmission filter cause slipping?
The internal parts of the transmission won’t have the necessary lubrication if the fluid is dirty or obstructed by a clogged filter. This can result in jerky shifting, gear grinding, slipping transmission, or other typical transmission problem signs and symptoms.
