What is Transmission Fluid?

When it comes to your transmission, it takes several components to keep it running smoothly. However, the most important part is the transmission fluid. It may not seem as though the fluid would be important, what with all the different gears and transfer of energy, but without being lubricated, all that will not work correctly.

It Works as a Coolant!

If you have an automatic, it is understandable with all the work your transmission is doing on its own that it may get overheated. However, thanks to automatic transmission fluid, it keeps everything cool. If for some reason, you smell a sickly-sweet burning smell you need to check your transmission fluid to make sure it isn’t getting low. If it is low, check for leaks, because transmissions don’t use up fluids like other parts of the vehicle.

Main Fluid Functions

It keeps all the gears and metal parts clean
It prevents grinding and metal shavings
Keeps not only transmission cool, but helps with the motor as well.
Helps transfer speed and energy
When to Change Fluid

Transmission fluid is unlike any other fluid in your vehicle. Unless you are having transmission issues, you should never really “need” to change your fluid. However, if anytime you check the transmission fluid and it is burnt or has shavings you should see a repair technician and see what the issue at hand is. If you feel as though your transmission fluid needs be changed just to be safe, consider around every 60,000 miles.

Leaking Transmission Fluid and Lack of Response Connected?

Leaking Transmission Fluid and Lack of Response Connected?

When it comes to trying to diagnose your car issues, it can be really hard to do for the untrained eye. If you don’t know a lot about cars, it is often best to go to a specialist. A lot of companies offer free consultations. This way you find out what is wrong and they get the opportunity to get your business. However, a lot of issues can be broken down to fluid and response.

Leaking Fluid

A transmission reuses the same fluid; it doesn’t use it up as your motor does. Therefore, if you start seeing your transmission is constantly low on fluid you most likely have a leak somewhere. It can be easy to spot a leak, just look under your car towards where your motor and transmission meet and see if there is a spot on the ground. Transmission fluid is a reddish color and smells sweet. When you run low on fluid, you can chip gears and over heat.

Lack or No Response

Your transmission is created to work like a machine. Transferring power from the motor and sending it to the axle. Sometimes where a transmission is getting worn out there becomes an issue such as lack of response, which can cause a slight loss of power. You can tell if this is happening if when you go into drive, and the motor revs to high rpm’s before taking off, then there is a response issue. Get to a repairman to see what the issue exactly is.

Often these two-run hand in hand. If you are having fluid issues, it can cause your transmission to lack response or quit altogether. A professional should handle transmission issues at all times. They require several different tools and part, making it outrageous for a normal person to handle. Contact Twin Transmission; they can assist you with all your transmission repairs and rebuild with little cost to you.

2002 Honda Accord Transmission Repair | Charlotte NC

Out of all the complaints or possible repair problems for the 2002 Honda Accord, nothing compares to the amount of complaints for repair with its transmission. Carcomplaints.com, a site where car owners can enter in repair complaint information, lists over 585 complaints for the 2002 Honda Accord, 511 of the complaints referring to the vehicle’s transmission. Transmission failure with the Honda Accord, Civic and Odyssey is a widespread problem in models made from 1999-2004. The 2003 Honda Accord, 2001 Honda Civic and 2002 Honda Odyssey appear to be the worst years for transmission failure.

Honda owners’ transmission problems are not a surprise to Dennis Madden, the chief executive of the Automatic Transmission Rebuilders Association. Mr. Madden said that in the 1990s there was a feeling that, “Wow, Honda really makes a great transmission. They last a long time.” But now, he said, Honda transmissions have a reputation as troublesome.

Consumer Reports’ 2010 reliability survey showed “major problems” with transmissions on the 2001–3 Acura MDX and TL, the Honda Odyssey and “to a lesser extent, Accord,” wrote Anita Lam, the magazine’s automotive data program manager. “Honda Civics and Pilots did not seem to share this problem,” she wrote in an e-mail.

Honda Transmission Repair Charlotte NCIt is important to fix transmission problems as soon as possible because allowing a problem to linger can cause permanent damage to your car. If your engine will rev up, but the car won’t shift into gear or move it could be a defective torque converter. In fact, the majority of Honda owners with transmission problems are saying the torque converter is failing and essentially burning up the transmission fluid, rendering the entire transmission useless. Be aware of your car slipping into neutral. Some Honda owners have also reported that the car’s transmission pops randomly into neutral, which causes grinding when traveling at high speeds.

  • transmission hesitates and shifts very hard
  • shakes when downshifting
  • won’t go into gear
  • bearing noise when accelerating
  • torque converter is going out

Do You Need a Transmission Flush?

Do You Need a Transmission Flush?

If you are considering having your transmission flushed, you need to take a couple of things into consideration. Are you having any transmission issues? When was the last time you had your fluid changed? How many miles do you drive yearly? These are just a few of the questions to ask yourself. Really the only time you need a flush is if you recently had any transmission issues.

What is a flush?

A transmission flush is a lot like a fluid change. However, the difference between them is a change just drains old fluid and replaces it with new. A flush, on the other hand, removes all the fluid, cleans the inside of the transmission and removes any debris that may be in there. This can tell you if your transmission is having any issues, such as overheating or grinding. You typically only need to do a flush once in the cars lifetime.

How much does it cost?

When it comes to cost, a transmission flush is like every other service, it all depends on. High-end cars can end up costing more than your basic car flushes. This is because they often require more labor, special tools, and even different fluid types. The cost also depends on where you live, the type of shop you use, and the amount of fluid needed. Talk to a transmission repair specialist in your area for an estimate.

You should contact your transmission specialist before deciding on a flush. There are a lot of pros and cons to consider. Some people believe that a flush can do more damage than it helps. Flushes have been known to dislodge slug and debris and send it to areas that can end up causing damage. Therefore, you should only get a flush is the specialist says so. Contact Twin Transmission today to find out if a flush is right for you.

How to Find a Trustworthy Mechanic

How to Find a Trustworthy Mechanic

Your transmission, one of the most important parts of your car is finding itself on its last leg. But what does that mean, new car, a repair, a rebuild?

With the vast amount of transmission specialists out there it is easy to be overwhelmed by the choices. We’re here to help.

Never Go with The First One

As with every service, you want to call around until you find one that fits your requirements. Those requirements should be experience, price, helpfulness, and friendliness. Often this can take calling a few different places. However, you should never go with the first person you call. If they seem legit, at least find a few more places to compare them to. Ensuring you get the best deal.

Have the Right Qualifications

A transmission repair, let alone a rebuild is a very big job. Therefore, not just anyone can do it. Make sure whatever repairman or company you choose to go with has the right qualifications. Not only in over-all experience in transmission repairs, but in your specific type as well.

Just Ask Around

When all else fails, and you’re not sure where to even begin sometimes it is best just to ask around. Friends, family, and co-workers are often the best place to start when looking for new places. Ask them who they used for transmission issues and if they would ever go there again. This can tell you a lot about who you can trust.

Is Your Transmission About to Bite the Dust?

Is Your Transmission About to Bite the Dust?

Think of your car as a machine, a well-oiled machine. When one part of that machine breaks, the rest of it will soon follow. Therefore, if you start to feel like you are having transmission issues, it can be in your best interest to get to a repairman as soon as possible. Otherwise, you can be left with a completely broken down car. Spotting a transmission issue is rather easy, it will either start making sounds or start losing power.

Strange Sounds

A healthy transmission is a quiet one. Therefore, if you have any odd sounds coming from under your vehicle, you will need to see what the issue is. Manual and standard transmissions have different sounds when messing up. A standard will often have a grinding sound or feeling when trying to shift into a different gear. Often, this grinding is the clutch seizing up, but it can lead to more serious issues. An automatic will typically hum, buzz, or whine when starting to go out. If you are having any of these issues, seek professional help.

Delay or Stalling

Your transmission is what takes power from your motor and sends it to the axle making you go. If your car is delaying or flat out stalling it can put you in harm’s way. The transmission is designed to keep you in the designated gear if you are stalling, or even delaying going into a certain gear, you need to first check fluid levels, and if all reads right, you could have a bigger issue at hand.

They offer free diagnosis and estimates. This can end up saving you hundreds more than several other transmission companies out there.

Rebuilt Transmission Specialist | Charlotte NC

Rebuilt Transmission Charlotte NCThe Transmission is one of the most complicated parts of your vehicle. Inside one transmission contains hundreds of parts, ranging from gears, seals, valves, gaskets, clutches, clutch disks, and many other transmission components. But what happens when a transmission fails, gears start slipping, or your car won’t move? What does a rebuilt transmission cost and what is done when a transmission is rebuilt?

As Charlotte NC ‘s best rebuilt transmission specialist. We have been rebuilding all types of transmissions for over 30 years, ranging from Honda Accords to Ford Explorers (all makes and model vehicles.)

Rebuilt Transmission Process
The rebuilt transmission process can be very time-consuming. The labor required to rebuild a transmission varies depending on the type of vehicle and transmission itself. Rebuilding a transmission should only be left to a specialist in this field.

First the transmission is removed from the vehicle. Then the transmission is completely disassembled. The fluids are drained and all the parts are inspected. The parts are cleaned completely during inspection. Internal parts that are replaced are: friction lined clutches, bands, seals, bushings, gaskets, molded rubber pistons, filters, and sealing rings. (These parts are called “soft parts” and should always be replaced with any transmission rebuild). Components replaced are updated with new quality parts.

Other components, referred to as “hard parts”, are replaced when they do not meet critical tolerance limits or are high failure rate items for the particular application. “Hard Parts” are transmission parts that in general should not wear out, but do sometimes, therefore requiring replacement upon a rebuild job. Sometimes the wear is very obvious, but other times it is discovered only during the disassembly and inspection of a rebuild in process. If a hard part components does need to be replaced, this can often add to the cost of the rebuilt transmission, since this is an additional item in the transmission rebuild process. Hard Parts to a transmission include front pump assemblys, Sprag clutches, Clutch Drums, Planetary Gears, Shafts, transmission case, Transmission Sun gears, Clutch hubs and much more.

After parts have been cleaned, inspected, replaced as needed — the entire transmission is reassembled. New transmission fluid and transmission testing completes the process.

Rebuilt Transmissions have the potential to restore a vehicle’s transmission to peak operational efficiency and to result in a long-lasting transmission. A vehicle with a rebuilt transmission can often times be driven for thousands and thousands of miles, even for the life of the vehicle in some cases, before requiring any further transmission repair.

Signs of a transmission problem, such as gears not shifting properly, loss of gears, car will not move, red fluid leaking underneath the vehicle — these can all result in a transmission repair or rebuilt transmission. As the rebuilt transmission specialist in Charlotte, NC we can determine if you are in need of a transmission repair. If you think you have a transmission problem, please contact us at 704-821-3460 for a transmission diagnosis. All diagnosis’ are free with repair.

Why do I need a professional Transmission Diagnosis for my Transmission problem? What does a Transmission Diagnosis involve?

For the most car drivers, the Automatic Transmission is a mystery. Put your gear selector in “D” for Drive–the vehicle goes forward. Put your gear selector in “R” for Reverse–the vehicle goes backward. Put your gear selector in “P” for Park–and the vehicle stops so you can cut the engine off. Most car drivers may know that the transmission requires fluid, but they have probably never checked the levels. So when the transmission becomes hard to shift, gears are slipping, making noises or when the gears do not work properly, most car drivers do not have a clue to what has caused this problem. This is why a Transmission Diagnosis is very important.

transmission diagnostic twin 02102011jpg resized 600An Automatic Transmission Diagnosis involves special computer system scan tools, specialized hydraulic pressure testing equipment, and advanced technician training.  Here at Twin Automotive, we use the newest and most advanced computer technology to diagnose your transmission or automotive problem. Using a device that mimmicks the look of a handheld tablet or laptop, we connect this special computer system to your vehicle. This tool will read not just the codes from any check engine light malfunction, but also reveal information that gives us an inside look at the problems with your vehicle.

Merely retrieving a code and trying a part, without an Automatic Transmission Diagnosis, will do little to repair the problem and may even damage expensive automatic transmission or emission control components.

When there is a problem with your transmission, the best thing to do is to call us immediately. Transmission problems only worsen with time. The sooner you have a transmission diagnosis performed and the problem fixed may be the difference between a minor transmission repair and a major costly transmission repair.

Automatic Transmission Problems & Diagnosis

When an automatic transmission is malfunctioning, it may exhibit one or more symptoms, such as harsh or delayed shifting, the loss of one or more gears, engine RPM “flare ups” between shifts, fluid leaks, slipping or lack of power to the drive wheels, and/or Check Engine Light or transmission overdrive illumination. When these types of symptoms occur, it is important to have an Automatic Transmission Diagnosis.

One of the most common complaints with automatics is fluid leaks. Fluid can leak out of the driveshaft seals, the input shaft seal, the transmission pan gasket, the torque converter or the ATF cooler and line connections. If the fluid level gets low, the transmission may be slow to engage when it is shifted into drive. Gear shifts may be sloppy or delayed, or the transmission may slip between shifts. If the fluid level is really low, the transmission may cause the vehicle to not go at all

If a vehicles Check Engine light is on, it means the computer has detected a fault and has set a diagnostic trouble code. There is no way to know if it is an engine code, transmission code or body code, so you will have to plug a scan tool or code reader into the diagnostic connector to extract the code.

If the transmission OD (overdrive) light is on or flashing, it means the transmission controller has diagnosed an internal transmission fault. To diagnose the problem, a scan tool that can read transmission codes must be plugged into the vehicle diagnostic connector (usually located under the dash near the steering column). The scan tool will then display the transmission code(s) that turned the warning light on. What happens next depends on the code. If the code indicates an internal performance problem, the transmission will probably need special attention to determine the problem and repair. But if the code indicates an electrical fault, it may mean a bad sensor or solenoid. When this problem is displayed, it is important to determine if there are any other underlying problems to the electrical fault. Replacing a damaged solenoid may only temporariliy fix your problem, until it breaks again, and then you have to start the process all over.

Electrical fault codes are set when the transmission controller or PCM detects an open or a short in a shift solenoid, shaft speed sensor or other device. Performance codes are set when the computer sends out a command, such as a 2-3 shift, but the transmission does not respond properly. Don’t be fooled by a faulty sensor or solenoid only replacement. Many of these problems have more underlying issues that need to be solved to prevent the same error from happening again.

How to Tell if Your Transmission is Failing

How to Tell if Your Transmission is Failing

Your vehicle is prone to have an issue or break down completely. However, it can be hard to tell exactly where the issue is coming from. Whether it is the motor, transmission, or something completely different. Only a trained eye can really tell you exactly what the issue is and steps needed to fix it. However, there are some tips and tricks that can help you figure out where exactly the issue is coming from. First, we are going to tell you about common transmission issues.


Your vehicle’s motor isn’t the only part that can overheat; the transmission can occur as well. One way to tell if your transmission is overheating is a burning smell. Since transmission fluid is really sweet smelling it is easy to tell if it has a burnt smell because it is very distinguished. The main reasons for your transmission to overheat is low fluid levels or even using the wrong type of fluid. The transmission is like all the other parts of your car; they have to be lubricated correctly to run right.

Slipping Gears

This is ones of the most dangerous issues your transmission can have. Imagine driving down the highway, and your transmission slips out of gear, and you lose power. You will be stuck in the middle of highway traffic; this is completely unsafe. Therefore, if your transmission is slipping get it to a repairman as soon as possible. Your transmission is designed to stay in gear, therefore if the transmission is slipping into another gear or popping into neutral, there is a possibility that you could break a gear which can be rather costly.

The transmission is not something you should try to fix alone. Contact Twin Transmission today to get your transmission looked out before it gets further damaged. Just a phone call could save you thousands and even your life.

Check Engine Light: Transmission Issues?

Check Engine Light: Transmission Issues?

Great, the dreaded check engine light started flashing in your car again. Not matter how much you look at the engine, fill all the fluids, and make sure it’s working properly, you just can’t seem to make that thing turn off. Well, did you know that just because it says “Check Engine” doesn’t necessarily mean something is wrong with the engine itself? There is a long, long list of issues that can make that light go off. One of them is the transmission.

Diagnostic Scanner

There is only one true way to know why the check engine light is on, that is to go to a repair center and have them run a diagnostic scanner. These scanners show codes and each code represent a different issue your car has. A repair tech can tell you what each code means. This is the best way to know what your issues.

Transmission Issues

If you don’t want to flat out take your car to the technician to run the scanner, there are a few signs you can look for that can let you know if your transmission is acting up. Grinding noise, this is an indication that something is off in your transmission. Either you have no fluid, or something has broken inside. You can check the fluid with the dipstick. However, if it shows full, get to a repairman ASAP. Another main transmission issue is slow or no response, when you shift gears, it should engage instantly, and lack of response can mean big transmission issues. Replacing a transmission is not only costly, but it also puts you without a vehicle for quite some time. Have it looked at before it comes to whole replacement.

Twin Transmission not only offers free transmission diagnostics, but they also have the scanner for your engine light. Stop by today to figure out the issue causing that pesky light.
