Top 5 Essential 8L90 Transmission Upgrades for Improved Performance

When the 8L90 transmission was first introduced, it was a significant technological advancement. Made by General Motors, this 8-speed transmission is more efficient and lightweight than the previous 6-speed transmissions and was designed for high performance vehicles such as the Chevrolet Silverado, the Cadillac CT6, and Chevrolet Corvette. 

While the 8L90 transmission was far superior to previous transmissions at the time, some design flaws were discovered over time. If you happen to have a vehicle with an 8L90 transmission, you may have experienced a few problems. But worry not. Some basic upgrades can correct common issues with your transmission. 

Consider the top 5 essential 8L90 transmission upgrades for improved performance. 

1. Clutch Packs. 

It can help to add extra clutches to some clutch packs in order to increase capacity. Replacing friction plates with high-performance friction material, such as high-energy fibers, allows for smoother shifting and reduction in shuddering. 

2. Steel Plates.

The stock steel plates on an 8L90 transmission tend to fail under heavy loads, resulting in poor shifting and slipping clutches. Replacing them with stronger steel plates improves transmission performance with increased torque capacity and improved heat dissipation. 

3. Input Shaft. 

Upgrading the input shaft on an 8L90 transmission can improve performance for heavy towing and high horsepower situations. The use of 300M alloy steel increases strength, durability, and longevity of your transmission.

Why We Use Remanufactured Transmissions for Your Vehicle

When it comes to major transmission work, we at Circle D Transmission prioritize providing reliable, high-quality solutions. For most cases where your vehicle requires a complete transmission rebuild, we use remanufactured transmissions from either the original equipment (OE) manufacturer or Jasper Engines and Transmissions. 

Here’s why this is the best approach for our clients, explained through five key reasons.

Reason 1: Quality Assurance with Trusted Brands

Signs of a Failing Transmission: When to Seek Transmission Repair

The transmission is a crucial part of a vehicle. It transfers power from the engine to the wheels to make the car move. It is also called the gearbox because it shifts the gears in the vehicle to increase or decrease speed. A vehicle may have an automatic transmission where the gears shift automatically as you accelerate or decelerate, or it may have a manual transmission, which means the driver must shift the gears. 

A vehicle’s transmission is built to last for around 100,000-150,000 miles with regular maintenance, but it may last longer or fail sooner depending on many factors. What are the signs of a failing transmission? How do you know when to seek transmission repair? Learn to recognize the common indicators. 

Check Engine Light Comes On 

As you probably know, the check engine light in your vehicle may come on for any number of reasons. If you take your car to a mechanic, they can check the code that indicates the reason for the check engine light. It may indicate that there is a problem with your transmission, or it may be something else entirely. 

Shifting is Rough or Hesitant 

If your automatic transmission is not shifting smoothly or as soon as you think it should, you may need to seek repair. In a manual transmission, if you feel that the gears are grinding or not shifting smoothly, it may mean that repair is necessary. 

Leaking Transmission Fluid 

If you notice any leakage underneath your car, it could be your transmission fluid. Transmission fluid tends to look dark brown or red in color. It is not as thick as oil, but thicker than brake fluid, so you may need to inspect it closely. If it smells burnt, that indicates a problem with your transmission. 

A Burning Smell When Driving or After Parking 

When your transmission is not working properly it can become overheated or burn transmission fluid, which results in a burning smell. You will typically notice it while you are driving or after you have driven for a while and then park. It may intensify as the gears shift, especially in city driving when you are constantly changing speeds. 

Excessive Shaking of the Center Console 

A failing transmission can cause vibrations or shaking of the center console where the gear shift is located. This could indicate a lack of transmission fluid or contamination of the existing fluid. It could also be caused by a damaged clutch that needs to be replaced. 

Abnormal Noises Coming From Under Your Vehicle

If you hear unusual noises or a sudden increase in noise coming from under your vehicle, it is most likely due to problems with your transmission. Noises from the engine indicate other problems, but the transmission is located under the center console in most vehicles. Be careful not to confuse it with your muffler, which is located near the rear bumper of the car and will cause excessive noise if it is damaged. 

Where To Seek Repair 

In the Houston area, there is no better transmission repair center than Circle D Transmission. We specialize in transmission diagnosis and repair on a wide variety of vehicle makes and models, including performance transmissions. We source quality parts for transmission repairs, rebuilds, and conversions. 

If you’re having any problems with your transmission, call 713-895-7019 or contact us today to schedule a service appointment. 

The Importance of Regular Transmission Maintenance

A closeup of mechanical gears in machinery.

Your transmission plays an essential role in your vehicle. Essentially, a transmission transfers the power the engine generates to the wheels. It also controls the degree of power the wheels receive, ensuring you can moderate your speed and reliably start and stop a vehicle.

Just like many car components, a transmission is a complex piece of machinery. That means it requires regular maintenance.

Don’t delay in scheduling this service! Staying on top of maintenance now can save you more money on repair bills in the long run.

Why Regular Transmission Maintenance is Essential

There are many reasons consistent transmission maintenance is vital. The following are merely some particularly noteworthy examples:

  • Identifying problems: There may be times when it’s necessary to repair or completely replace a transmission. No automotive part lasts forever. However, regular maintenance can help you extend a transmission’s lifespan. During maintenance tasks, a transmission repair professional may spot the warning signs of developing problems. Addressing minor issues now before they become more significant problems can benefit both your safety and wallet.
  • Saving money on gas: Often, a properly-working transmission will help a vehicle optimize its gas mileage. You may save money at the pump (and conserve resources) by staying on top of transmission upkeep.
  • Topping off transmission fluid: The team performing transmission maintenance will usually check to confirm whether your transmission needs more fluid. They will typically add more if necessary. Ensuring your transmission has sufficient fluid will prevent it from overheating. In addition, proper lubrication can reduce wear and tear on your transmission. This is another way in which regular transmission maintenance can maximize a transmission’s lifespan.

You may also notice your vehicle operates more smoothly after undergoing transmission maintenance. Be aware, many components of a motor vehicle affect each other. A transmission that’s in good working order will optimize the lifespan of the entire vehicle.

DIY Transmission Maintenance Tips

There are some transmission maintenance tasks, like thorough inspections, that professionals must perform. Check your vehicle’s owner’s manual to learn how often the manufacturer suggests scheduling transmission maintenance.

However, there are some basic steps you can take on your own to improve a transmission’s performance and guard against failure. They include:

  • Check fluid levels: Your owner’s manual should include information regarding how to check transmission fluid levels and how often you should do so. Follow the manufacturer’s recommended schedule.
  • Check for leaks: Monitor the areas where you park your vehicles for signs of fluid leaks. Transmission fluid often appears red when it leaks. However, in some cases, it may appear blue or green. Regardless of the color, you should always have a professional take a closer look when your vehicle is leaking any type of fluid.

A professional can also offer additional tips for keeping your transmission in good shape. By scheduling regular maintenance and following professional advice, you’ll save a lot of money on repair service in the long run.

6R80 Ford Lead Frame Problems

A Ford 6R80 lead frame on the ground

The molded lead frame houses the transmission output speed sensor and connects to the shift solenoids on the valve body of your transmission - it is a critical component. We commonly find lead frame issues in the Ford Expedition, Ford F-150, Ford F-250, Ford Mustang, Ford Transit, and Lincoln Navigator. Remember that attempting to fix a transmission when you don’t know what you’re doing can cause more harm than good. Thus, it’s best to hire transmission repair professionals if you’re unsure how to address a possible lead frame issue.

Symptoms That You May Be Having a Lead Frame Issue

  • Vehicle may not start
  • Vehicle may not shift out of Park
  • Vehicle may downshift while driving on the highway / harsh downshifting
  • Vehicle may have Output Speed Sensor, Input Speed Sensor, and/or Range Sensor DTCs (Diagnostic Trouble Codes)
  • Speedometer may not work or only work intermittently

The Importance of Addressing Possible Lead Frame Issues Promptly

At Circle D Transmission, we are familiar with this common issue and only use OEM replacement lead frames. If you’re having problems similar to those listed above, please reach out to us as soon as possible so that we can possibly correct the issue by replacing the lead frame and not the entire transmission. As long as we confirm that the lead frame is the issue and that the transmission pan does not show signs of metal debris, we most likely can be successful in rectifying your transmission’s issues by replacing the lead frame. Never ignore a potential lead frame transmission problem, and never attempt to fix the problem on your own if you’re unsure how to do so. When you address a transmission issue promptly, you may prevent a minor headache from becoming something much more significant.

Common Transmission Problems and Their Solutions

A person with their hand on the stick shift puts a car into gear

Your vehicle’s transmission is a complex machine within a complex machine (a car). As is the case with any such machine, it can stop working for various reasons.

Understanding common transmission problems and how to fix them can help you save money over the years by minimizing the need for repairs. The following overview covers some noteworthy transmission issues you may encounter, along with how to fix them.

Just remember that attempting to fix a transmission when you don’t know what you’re doing can cause more harm than good. Thus, it’s best to hire transmission repair professionals if you’re unsure of how to address an issue.

Common transmission problems drivers face include:

Transmission Won’t Stay in Gear

Does your transmission fail to easily engage when shifting gears? Or, does it not stay in gear?

Low transmission fluid may be the culprit. Check your transmission fluid levels and add more if you’re running low. 

If addressing low transmission fluid levels doesn’t fix the problem, a shifter cable issue may be the cause. Fixing a shifter cable is something only a professional can do.

Fluid Leaks

Transmission fluid is bright red. Check for transmission fluid stains around all areas you regularly park your vehicle.

Again, low transmission fluid can cause problems. You may add more fluid to address the immediate issue of low transmission fluid levels. However, if you suspect a leak, you’ll have to get an expert to take a closer look. They can determine the leak’s cause.

A Burning Smell

A burning smell when you operate your vehicle is always an issue requiring immediate attention. Often, a transmission leak is the cause.

Get in touch with a professional to address the leak as soon as possible. If you don’t repair a transmission leak in a timely manner, the transmission itself can become damaged beyond repair. You may need to replace your transmission entirely if this happens.

Strange Noises

Your transmission may generate noises you haven’t heard before. Common descriptions for transmission noises include humming, buzzing, and clicking, among others. Some transmission noises are so loud that drivers describe them as roars.

Damage to one of the transmission’s components is likely to blame for these new sounds. Or, a component may be loose. If you lack the expertise necessary to inspect a transmission and repair or replace a damaged part, contact a transmission specialist for assistance.

Shaking at High Speeds

Does your vehicle shake when traveling at high speeds? There are various potential causes for this problem. Because a shaking vehicle can increase your chances of being hurt in a collision, it’s vital to have a specialist take a closer look at your vehicle. They need to confirm the cause of the issue so you can be confident you’re fixing it thoroughly.

A vehicle may shake when traveling at high speeds due to a transmission issue. Per news reports, some vehicle brands like Chevrolet have been the targets of lawsuits due to their faulty transmissions causing this type of problem. If your vehicle needs a new transmission, installing it is a job for the professionals.

The Importance of Addressing Transmission Issues Fast

Never ignore a potential transmission problem, and never attempt to fix the problem on your own if you’re not sure how to do so. Your vehicle can’t run properly without a properly working transmission!

These tips will help you identify the early signs of an issue. When you address a transmission issue fast, you may prevent a minor headache from becoming something much more significant.

What You Need to Know About Transmission Fluid

A person standing underneath a vehicle uses a computer sensor to diagnose transmission problems

Your transmission fluid plays a critical role in your vehicle’s functioning. Thus, it’s important to check your transmission fluid at least once a year. 

Don’t just check transmission fluid levels. Check the color of your transmission fluid as well. Its appearance can tell you whether you need to replace it.

What Does Transmission Fluid Do?

Whether your vehicle has a manual transmission or an automatic transmission, when gears shift, it can put a significant degree of wear-and-tear on the vehicle’s parts. Transmission fluid helps to lubricate these parts. According to Universal Technical Institute, transmission fluid also ensures that transmissions remain fairly cool.

What You Need to Know About Checking Transmission Fluid

The best resource for information about checking and replacing your transmission fluid is your vehicle’s owner’s manual. It will provide directions on how to check transmission fluid in your specific model vehicle.

The owner’s manual will also explain what type of transmission fluid your vehicle uses. As Car and Driver points out, different types of transmissions use different types of transmission fluids.

You may check transmission fluid with the dipstick. You can usually find the dipstick under the hood in the engine compartment. Look for a transmission symbol or other such marking to confirm you’re using the transmission dipstick and not the dipstick for checking engine-oil.

The process for checking transmission fluid with a dipstick typically involves:

  • Warming up the engine
  • Parking the car on a level surface and letting it idle
  • Removing the dipstick
  • Wiping the dipstick clean
  • Placing the dipstick back in its original location
  • Removing the dipstick again

The dipstick will have “low” and “high” marks letting you know whether your transmission fluid levels are low or high. However, your goal now may be to check the color and overall appearance of the transmission fluid. The next section of this guide will explain the process.

Be aware that some new vehicles have sealed transmissions. If yours does, you may never need to check transmission fluid levels.

What the Look of Your Transmission Fluid Tells You

Get out a paper towel, a sheet of printer paper, or another such white surface to rest the dipstick on. Make sure you’re not near any surfaces that dripping transmission fluid could stain.

Healthy transmission fluid tends to have a red or pink color. As its condition deteriorates, the color becomes brown-red. It’s time to replace your transmission fluid if it looks like this.

Sometimes, transmission fluid appears dark brown or even black. It may even have a burnt smell.

Bring your vehicle to a transmission service specialist if this is the case. At this point, it may no longer be enough to replace your transmission fluid. You might have to also replace internal transmission components that are damaged.

Checking Transmission Fluid: A Simple Way to Save Money

Replacing your transmission’s internal parts is costlier than replacing the fluid. That’s why checking the fluid at least once a year is smart. If you know when to replace your transmission fluid before damage occurs, you could save a lot of money on repair bills over the years.

How Long Does It Take To Install A Transmission?

A person uses a wrench to install a transmission in a car

Your vehicle’s transmission plays a critical role in its performance. To understand what exactly a transmission is and how it functions in a motor vehicle, it’s sometimes best to think of a transmission as serving the same function that a bicycle’s gears, chain, and shifter serve.

The transmission is a complex piece of machinery made up of several different moving parts. As is the case with any such piece of machinery, it can fail over time.

You may need to have your transmission replaced one day. When this day comes, you might wonder how long the process will take. Keep reading for more information. The following guide explains what you need to know about the process.

Signs You Need a New Transmission

Various warning signs may indicate it’s time to replace your transmission. Example include:

  • Check engine light: The check engine light turning on can signal a range of potential issues. Often, this light will turn on when there’s a problem with the transmission. Bring your vehicle to a professional to learn more. Remember, the longer you drive with the check engine light on, the more the problem will simply worsen.
  • Noise: Monitor your transmission for any grinding, banging, or similar noises. Such noises often mean the transmission is in need of repairs or replacement. Be aware, the noises that come from a failing transmission aren’t always particularly loud, so you may need to pay close attention to hear them.
  • Dark or cloud transmission fluid: Get into the habit of checking your transmission fluid (and all your vehicle’s other fluid levels) at least once a month. When doing so, inspect the condition of the transmission fluid. The transmission may not be functioning properly if the fluid is dark or cloudy. In addition, a burnt smell coming from the transmission fluid may be a sign of a problem.

These are just a few warning signs of a transmission issue. The moment you suspect a problem, make an appointment with an expert who can take a closer look and determine whether your transmission needs replacing.

Replacing a Transmission: How Long it Takes

There’s no universal answer to the question of “How long does replacing a transmission take?” Several factors can influence how long it may take to replace a transmission. They include:

  • Vehicle make
  • Vehicle model
  • Vehicle age

In some instances, it also might not even be necessary to replace an entire transmission. Depending on the nature of the issue, it may be possible to address the problem while merely replacing a single component.

That said, a typical transmission replacement may usually take about two days or less. However, for more complex jobs, the process can take three to four days. Make arrangements accordingly if you won’t have a vehicle while your transmission is being replaced.
