Whether you drive a QX50, QX60, or the full-size QX80, staying ahead of transmission issues starts with spotting the early warning signs. In 2025’s performance-driven luxury SUVs, transmission fluid does more than lubricate—it keeps your drive smooth, your transmission cool, and your powertrain protected.
In this guide, we’ll break down the top 5 symptoms of low transmission fluid every INFINITI driver should know. And if you notice any of these red flags while driving through Valencia, Santa Clarita, Acton, or Agua Dulce, don’t wait—visit or contact the INFINITI of Valencia service department today. Our certified technicians are ready to diagnose the issue, recommend the right INFINITI transmission fluid type, and get you back on the road with confidence.
1. Delayed or Erratic Shifting in Your INFINITI
What It Feels Like and Why It Matters
One of the most common signs your transmission fluid is low is a delay when your car shifts. You may feel it when you move from Park to Drive or Reverse. The change doesn’t happen right away. Sometimes, it can take two or three seconds before the gear responds.
In some cases, the shift feels rough or jerky. You may also notice that the car slips between gears while you drive. These are all signs that your transmission is not getting the pressure it needs to work right.
If you drive an INFINITI QX50, these issues can be more clear. This model uses a smooth, responsive transmission system. When the fluid is low, that system can’t do its job. You might feel like your SUV is lagging or jumping when you press the gas.
Here are common shifting issues to watch for:
- A delay when switching between gears
- Jerky or rough gear changes
- A gear that slips or won’t engage
- Lurching forward or back while driving
- Lagging when moving from a full stop
These symptoms often get worse if left unchecked. Low fluid reduces the pressure inside the transmission. That pressure is what helps the gears shift fast and smooth. When it's not there, the parts struggle to work together.
If you notice any of these signs, it’s time to take action. The issue may not go away on its own. The longer you wait, the more damage can happen.
The best next step is to have your vehicle checked by trained experts. The INFINITI of Valencia service department can check your fluid levels and the health of your transmission. Their team knows your INFINITI inside and out. They’ll help fix the issue before it leads to bigger repairs.
Even a small delay in shifting can point to a bigger problem. It’s smart to handle it early. Your QX50—and your wallet—will thank you.
2. Hearing Grinding or Thumping Sounds? It Could Be Low Fluid
Noises That Signal Trouble in Your Transmission
Strange sounds from your car are never a good sign. If you hear grinding, thumping, or clunking, it could mean your transmission fluid is low.
These sounds happen when the parts inside your transmission aren't getting enough fluid to stay cool and smooth. Metal parts rub too hard. That friction makes noise—and that noise means trouble.
If you drive an INFINITI QX60, these sounds may show up during gear shifts or after you come to a stop. Some drivers report a “thump” just as they press the gas again. Others hear a clicking or grinding when switching gears or climbing a hill.
Listen for these warning sounds:
- Thumping right after stopping or before accelerating
- Grinding when shifting into Drive or Reverse
- Clicking or clunking during gear changes
- A constant humming or whining at low speeds
Low fluid can’t protect the gears from heat and wear. Over time, this causes the parts to break down or fail. What starts as a simple sound could lead to a major repair if ignored.
These symptoms don’t always mean a full breakdown. But they do mean it’s time to check your transmission system. That starts with checking the fluid.
The team at INFINITI of Valencia service will know what to look for. They can check for leaks, inspect the fluid, and see if more fluid is needed. If the fluid is too dark, smells burnt, or is too low, they’ll recommend the right fix using the correct INFINITI transmission fluid.
Hearing sounds like these? Don’t wait for things to get worse. Schedule a checkup with a trained technician and keep your QX60 running the way it should.
3. A Burning Smell or Overheating Means It’s Time to Act
Heat and Odor Are Warning Signs You Shouldn’t Ignore
If you smell something burning while driving, it could mean your transmission is overheating. This is a clear warning sign.
Your transmission fluid does more than help gears shift. It also keeps the system cool. When the fluid runs low or breaks down, heat builds fast. This can lead to damage deep inside the system.
Drivers of large SUVs, like the INFINITI QX80, may notice this more often. These vehicles work hard, especially when hauling or driving in heat. When the fluid can’t handle the load, you may start to smell that sharp, burnt odor.
Watch for these signs of heat trouble:
- A hot, burning smell from under the hood
- Smoke near the engine or under the vehicle
- Harsh or delayed shifting after long drives
- Warning lights for high transmission temps
These problems are serious. Burnt fluid means the oil has lost its cooling power. The parts inside the system are getting too hot. This can cause the seals to harden, the clutches to wear, and the whole system to fail.
If you smell burnt oil or see signs of heat, it's time for a transmission check. You may need a full inspection and a proper INFINITI transmission fluid change.
Changing the fluid helps cool the system again. It also clears out any sludge that may cause the heat to rise. This is one of the best ways to protect your QX80 from costly repairs down the road.
If you drive in the heat or haul heavy loads often, fluid changes are even more key. Your SUV depends on it to keep things cool and working right. Don’t ignore a smell that seems off. It might be your first and only warning.
4. Noticing Puddles? Leaking Transmission Fluid in Your Driveway
How to Spot a Transmission Fluid Leak Early
Finding a puddle under your car can be alarming. If the liquid is bright red or brownish, it might be transmission fluid. A leak like this means your vehicle is losing the fluid it needs to work well.
If you drive an INFINITI QX50, a leak can cause serious problems fast. Without enough fluid, your transmission can overheat and wear out. Catching a leak early saves you from bigger issues.
Here’s how to tell if the leak is transmission fluid:
- Bright red or reddish-brown color
- Slightly oily texture, not watery
- A sweet or burnt smell
- Located near the middle or front under the car
If you see dark or burnt-looking fluid, it means the problem has been going on for a while. This can increase the cost of repair and make your transmission less reliable.
Knowing the transmission fluid change cost ahead of time helps you prepare. Routine changes are less expensive than fixing leaks or damaged parts caused by low fluid.
If you spot any fluid under your car, don’t wait. Have your vehicle checked by experts who can find the leak’s source and fix it. Proper maintenance keeps your QX50 running smooth and safe.
Regular checks and service help avoid leaks and keep fluid levels right. This protects your transmission and can extend the life of your SUV.
5. Check Engine Light or Transmission Warning? Don’t Ignore It
What Your Warning Lights Mean for Your INFINITI QX60
When the check engine light or a transmission warning shows up on your dash, it’s a sign something is wrong. These lights can mean low transmission fluid or a related issue.
Modern vehicles like the QX60 use sensors to watch how the transmission works. If fluid levels drop or the fluid type isn’t right, the system alerts you. This helps prevent bigger problems.
Ignoring these warnings can lead to serious damage. The transmission needs the correct fluid to shift smoothly and last longer. Using the wrong INFINITI transmission fluid type can also cause trouble.
Here are some things to keep in mind if a warning light comes on:
- Don’t panic, but don’t delay checking it either
- Avoid heavy acceleration or towing until checked
- Schedule a service visit soon to prevent damage
- Use only the recommended transmission fluid type for your model
The service team can run a full diagnostic. They will check fluid levels, look for leaks, and test the transmission’s health. Early care means fewer costly repairs later.
If your QX60’s warning lights turn on, act fast. Getting help early protects your ride and keeps it running like new.
Why Monitoring Your Transmission Fluid Matters for INFINITI Drivers
Protecting Your Vehicle and Your Drive
Transmission fluid plays a key role in how well your car runs. It lubricates the parts inside your transmission, helps shift gears, and cools the system. Without the right amount of clean fluid, your car can face serious problems.
If you own an INFINITI QX50, keeping an eye on your transmission fluid is especially important. This model relies on smooth shifts and precise performance. Low or dirty fluid can cause jerks, slipping, and even damage.
Here are some reasons why checking your fluid matters:
- Keeps gears shifting smoothly
- Prevents parts from overheating
- Stops early wear and tear
- Helps avoid costly repairs
The best way to stay ahead of trouble is to have your fluid checked regularly. The team at INFINITI of Valencia service department can help. They know how to inspect and maintain your transmission for peak performance.
Regular maintenance means:
- Testing fluid levels and condition
- Using the right fluid for your model

Make sure to schedule regular service with trained experts who understand your INFINITI inside and out. It’s a smart way to keep your drive steady and stress-free.
How to Check Transmission Fluid Level in Your INFINITI
Easy Steps to Keep Your Transmission Healthy
Checking your transmission fluid level is a simple way to help your vehicle run well. If you drive an INFINITI QX60, regular checks can prevent many problems.
Here’s how you can check the fluid yourself:
- Warm up your car by letting the engine run for a few minutes.
- Keep the car in Park or Neutral, and the engine running.
- Find the transmission fluid dipstick under the hood. (Check your owner’s manual if you’re unsure.)
- Pull out the dipstick and wipe it clean with a cloth.
- Put the dipstick back fully, then pull it out again to check the fluid level.
- The fluid should be between the “Hot” or “Full” marks.
Good fluid looks clear and reddish. If it’s dark or smells burnt, it needs to be changed. Dirty fluid can hurt your transmission over time.
It’s also important to use the right kind of fluid. INFINITI models need specific transmission fluid to work best. Using the wrong type can cause damage.
If you’re unsure or find problems, the experts at INFINITI of Valencia service can help. They’ll check your transmission, add or change fluid, and make sure everything works right.
Regular fluid checks keep your QX60 shifting smoothly and lasting longer. It’s a quick step that can save time and money down the road.
