“My 17.5-year old car needed major work. I was doubtful as to whether or not I should invest more money in an old car, but Josh “did some research” and found a way to make the needed repairs affordable. My car now drives perfectly. It’s as peppy as when it was new! Both Josh and Lee assured me my satisfaction was their top priority and, so far, I’m well-pleased. I’ll surely recommend them to anyone I know who’s in need of courteous, competent, affordable service.” ★★★★★ – Hedy D.

“I needed to have my transmission looked at. I took it to the OEM dealership and they wanted to fix it for an astronomical amount of money. I called AAMCO, and spoke to Li, the owner. Li was awesome and walked me through every step of what was happening. He called me constantly to let me know where they were with my car and what was going on with it. He told me the cost associated to everything they were doing and gave me options that could save me money. In the end, I saved a little over $2k and my car is running great. I would absolutely recommend this location to anyone in need of transmission repair.” ★★★★★ – Joe T.

“Really appreciated the great customer service and how good the car ran after the car service was conducted. Josh was really helpful in finding me affordable transmission fit for my budget and was flexible to my schedule and knew how important it was to get me back on the road. Thank you Josh for your outstanding service in both areas. Five star service for sure!” ★★★★★ – Joe T.

Signs of a Blown Transmission and What You Need to Do

There are many reasons your transmission might fail. Poor automotive design is one of the most difficult to come to terms with, because it can cost you a lot of money to maintain and inevitably repair, even when you did not do anything wrong. Along with the design comes poor manufacturing on the automaker’s part, as well as cheap parts and little to no quality assurance on the production line. [Read more…]

Check Engine Light On?

There are many reasons your check engine light comes on, some simple to fix, some not so simple.

“These guys are awesome! They fixed my transmission and now my truck runs GREAT! I will definitely recommend AAMCO to all my friends.” ★★★★★ – Vic C.
“These guys were awesome, $0 diagnostic means $0 diagnostic. I was afraid I had a multi thousand dollar repair on my transmission due to the car being thrown into reverse while driving down the highway by my dog. Lee really worked with me and didn’t try and sell me anything I didn’t need. He let me know what the issues probably were even though it turned out the transmission was fine and referred me to another shop to take care of the issues. $0 dollars and great honest advice. Blown away by the customer service here.” ★★★★★ – Kyle H.

Top 10 Reasons Why You Might Have a Transmission Problem

You know your vehicle. So when it starts acting differently, you take notice. Are you currently hearing strange sounds or is there a peculiar smell coming from your vehicle? Is it handling differently than normal on the road? The most important thing is properly diagnosing the root cause of your vehicle’s issue. Below are the tops reasons or signs that you may require transmission repair:

The top signs your transmission may be failing:

AAMCO is the most trusted name in transmission repair and has been for over 50 years. What sets us apart is our comprehensive diagnostic approach, along with the knowledge and expertise to pinpoint the root of your transmission issue. You may be experiencing a problem with your transmission if your vehicle is exhibiting any of the following symptoms below:

  1. Transmission won’t engage or stay in gear If when you put your vehicle into gear and it won’t move, this may be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or it could even be a problem in the valve body of your automatic transmission. Newer vehicles depend on the computer to tell the transmission when to go into gear based on your selection and you may need to have the computer system checked for trouble codes.
  2. Shifts are delayed or missing gears If your transmission takes a while to go into gear, you may have a low transmission fluid condition because of a leak or contamination due to lack of maintenance or even water intrusion during off road or flooding conditions. While this may not sound serious, but this can also create an overheating condition that can damage internal transmission parts. Other possibilities could be an engine related problem that will cause the computer to not allow the transmission to shift into higher gears.
  3. Transmission slipping or engine is revving high This condition can also be caused by low transmission fluid, contamination due to lack of maintenance or water intrusion, or internal wear and tear on the transmission parts inside the transmission. A high revving engine is a typical sign that you have worn clutches or other parts inside the transmission going bad.
  4. Transmission fluid is leaking A red fluid under the vehicle is a sign that you probably have a transmission fluid leak from one of the cooler lines, a gasket or a seal. This is not only bad for the transmission but is also dangerous if the fluid leaks on a hot pipe or other surface. Check your dipstick for proper fluid level and condition. Note: not all transmission fluid is red and not all levels can be verified with a dipstick method, but require specials tools.
  5. If there’s a burning smell A burning smell is typically caused by a fluid leak or in some cases by low fluid causing a burning clutch smell. If you catch the fluid leak quickly you might be able to save the transmission from damage. Check your transmission dipstick as per the manufacturer’s direction for level and condition.
  6. If there is buzzing, clunking, humming noise A buzzing, clicking, humming, roaring noise from inside the transmission is usually a symptom of a bad bearing, planetary gears damage, or other internal problem. A buzzing could also come from a bad internal sealing surface, a seal, or low transmission fluid due to a leak.
  7. Car has no power If the vehicle has no or little power and the engine is running correctly, this could be from internal transmission problems, brakes that are dragging due to a faulty caliper or brake hose, or your computer in the vehicle is limiting power because of a problem it has detected in order to protect the engine. Have the vehicle checked for trouble codes to isolate the problem.
  8. Check Engine Light or Over Drive Light is on A check engine light is not dedicated to the engine only. A check engine light can also tell you that you have problems with the transmission including overheating, solenoid problems, speed sensors, slipping and many other problems. Have the trouble codes retrieved to see what systems and circuits are indicating a problem. While not all sensor related codes mean the sensor is bad or will repair the issue, it will give you a starting point for the concern.

Manual Transmissions:

  1. Gears are grinding when shifting  When your manual transmission grinds when shifting gears that is typically a condition related to the clutch not releasing, the shift synchronizer rings inside the transmission itself worn or broken, or a shifter wear or adjustment problem. Transmission oil/fluid that is low, dirty or the wrong fluid can also cause this problem in manual transmissions.
  2. The clutch pedal grabs very low or very high  A clutch pedal that engages very low is typically a problem with the linkage or hydraulic system that operates the clutch. A simple adjustment or bleeding might solve this if there are no hydraulic leaks. A clutch pedal that grabs very high could be an adjustment, or more likely a worn clutch disc and pressure plate.

What is Transmission Fluid?

image of car on lift, transmission fluid draining in long, red stream.Transmission fluid helps to keep the moving parts inside your car’s transmission moving smoothly. This fluid also helps keep the different parts of your transmission cool. Shifting mechanical gears is a hard task for your car. Transmission fluid allows your car to shift with ease while protecting the metal parts that rub against each other from wearing out. Most people know about engine oil since it requires changing often – but most people don’t know about the importance of transmission fluid and when to change it.

Automatic Transmission Fluid

If your car has an automatic transmission, it has. Additionally, some more modern manual transmission cars use fluid, too. Automatic transmission fluid is specially formulated for the requirements of an automatic transmission and helps with functions such as gear lubrication, brake band friction, and valve operation. Transmission fluid is one of the hardest working fluids in your car and it’s important to keep it clean and at the proper levels.

Manual Transmission Fluid

Also known as manual transmission oil, manual transmission fluid is used in some manual transmission cars. It is not interchangeable with automatic transmission fluid! Manual transmission fluid is never used in automatic transmission cars. Just because your car is a manual transmission does not mean that it uses manual transmission fluid. Manual transmission fluid can be a variety of different oils from normal motor oil to heavyweight hypoid gear oil. Always be sure to check your owner’s manual for the specifications for your car.

How to Safely Drive Manual vs. Automatic Transmissions

image of Fiat gear shift closeup

There are two types of transmissions that vehicles can be built with. These include either an automatic transmission or a manual transmission. There are several pros and cons to each that you want to consider before driving one or the other. How you drive these two types of transmissions will also change while driving in the snow during winter time. So make sure you know how to drive your particular car’s transmission when the time comes.

Whichever you choose, rest assured that AAMCO Colorado has you covered should you need any repairs – transmission or otherwise. If you end up grinding that manual transmission into oblivion as you learn to drive stick, we’ll fix it for you! [Read more…]
