The transmission is by far the most complex component of today’s vehicles, containing well over 200 parts on average. Due to its complexity, most transmission problems can’t be fixed by the average “do-it-yourself” mechanic and unfortunately many issues are misdiagnosed by general repair shops that do not specialize in transmission repairs. Having in depth knowledge on a vehicles transmission system is vital to providing a proper diagnosis and quality repairs. Taking your vehicle to an expert early on, at any signs of potential failure can save you a lot of time and wasted money.
Certified Transmission has been providing industry leading transmission service and repairs since 1967. Whether your vehicle is in need of a preventative maintenance service such as a fluid and filter change, a minor repair, or a major rebuild or replacement, the Certified team has you covered. Our technicians are ASE master certified and receive continual training so you can rest assured our team will get the job done right the first time.
Typical symptoms of transmission problems are:
- Leaking Fluid: Park your car in a clear, clean area for 24 hours. Then move the car and check for any evidence of liquid: drips or puddles. Red fluid is typically transmission fluid and may mean that you have a leak. Transmission fluid cools and lubricates the parts as they move. Low fluid can cause the trans to overheat and/or parts to wear down. (NOTE: Green may be antifreeze very poisonous to pets and children, and black fluid is usually motor oil.)
- Check Engine Light: The check engine light tells you that the car’s internal computer detects a problem in one of the operating systems. It could be the transmission, or it could be the engine, or exhaust, etc. Better safe than sorry on this one. Get it in to a professional with the proper diagnostic equipment.
- Something feels wrong: Grinding and shaking as you increase or decrease speed or shift gears can be a symptom of a serious transmission problem.
- Makes funny sounds: A transmission that is operating properly will not make noises. If you hear whining or humming, it’s a problem. Get it checked out. Note that the noises may only happen intermittently at first but will happen more and more frequently over time.
- Won’t go into gear: When an automatic transmission hesitates or has issues engaging “Park” or “Drive” instead of shifting quickly into gear there’s likely an issue with the transmission.

The transfer case is an essential part of all-wheel-drive (AWD), four-wheel-drive (4X4), and other multi powered axle vehicles. It is responsible for taking the power from the transmission and sending it to both the front and rear axles by means of the vehicles driveshaft’s. Another primary function of the transfercase is synchronizing the difference in rotation between the front and rear wheels. This is a vital component of the t-case (transfer case) system due to the fact that the vehicles tires are always turning at different speeds. Without this synchronizing ability, binding would occur which would cause premature tire wear, potentially dangerous driving situations, and damage to the transfer case and other vehicle components. The overall purpose of the transfercase and all-wheel-drive unit (in AWD applications) is to provide added traction on slick, loose, or slippery surfaces, creating a safer driving experience for the operator.

- Noise & Vibration Diagnosis
The primary function of the differential is to transmit power to the wheels, while allowing the outer drive wheel to rotate at a faster speed than the inner wheel during a turn. The differential also acts as the final gear reduction in the vehicle, slowing the rotational speed of the transmissions one final time before it hits the wheels. All vehicles produced today are equipped with either a front or rear differential, depending if the vehicle is front-wheeldrive (FWD) or rear-wheel-drive (RWD). All-wheel-drive (AWD) and four-wheel-drive (4X4) vehicles will have two separate differentials and either a transfer case or a center differential to displace the engines power.
Our team here at Certified Transmission has the extensive knowledge and expertise required to diagnose, repair, and rebuild a wide variety of differential & driveline issues for both domestic and foreign vehicles. Our highly trained team has specialized in differential repairs since 1967 and can handle any differential or driveline issue you may be experiencing. Give us a call today to see what sets us apart from rest!

- Leaking fluid from the front or rear of the vehicle
- Moisture on the front or rear differential
- Unusual “humming” or “whining” sound
- Noise on acceleration or deceleration
- Clunking noise around turns

In order to keep your warranty in full effect, you may be required to have certain services performed as prescribed in your owner’s manual or as required in the warranty. Typical Manufacturer recommended maintenance might include oil changes, filter changes, transmission, transfer case, differential and driveline inspections, etc.
As with your own health, preventative maintenance and early detection of problems will often save on larger repairs. Consult your owner’s manual for Manufacturer Recommended Maintenance and make sure to keep up with all of your services to ensure your vehicle is properly maintained. These are like “regular check ups” with your family physician. They ensure the mechanic is familiar with your vehicle and has an opportunity to point out small problems before they become big problems that could leave you stranded on the side of the road or worse, endanger your safety. You can trust team here at Certified Transmission Repair to thoroughly inspect your vehicle to ensure proper maintenance and extend the life of your car!
Who can perform my Manufacturer Recommended Maintenance?
In most cases your non-warranty maintenance can be performed by either a dealership or your own mechanic. (Double-check your warranty to be sure!)
Many independent repair shops can perform these services at costs that are very competitive with dealerships. They have access to the same information that franchised dealers have about model-specific problems and they may be familiar less expensive aftermarket parts that perform just as well as manufacturer parts.
The Magnusen-Moss Act of 1975 prohibits new car dealers from implying or denying warranty service because routine scheduled maintenance was performed at an independent repair facility. (Magnusen-Moss Act (1975) Title 15 Chapter 50-Section 2301-2312

"Took my truck in for them to look at so I could get an estimate of how much it would cost. Took them a week to get to it because they were busy and it was a holiday weekend. Once they called me they told me what was the problem and gave me the estimate of $350, which honestly wasn't that bad. They fixed it and returned it to me the next day and was a bit cheaper than they expected. They are truly certified!!!!" - Joseph DeMoss
