Transmission Leak Repair

Transmission oil leaks can be a common problem for many car owners in Barrie, and if not addressed promptly, they can lead to serious issues with the transmission system. Here are a few steps we take at our transmission shop in Barrie to repair a transmission oil leak:

  • Identify the source of the leak: The first step in fixing a transmission oil leak is to identify where the leak is coming from. We do this by checking for oil stains on the transmission case or nearby components.

  • Determine the severity of the leak: Once we have identified the source of the leak, we determine how serious it is. A minor leak may only require a simple repair such as replacing a gasket or seal, while a more severe leak may require a complete transmission overhaul or disassembling the transmission to access a broken seal.

  • Replace the damaged parts: If the leak is caused by a damaged gasket or seal, we replace the damaged part. This may involve removing the transmission from the vehicle and replacing the damaged gasket or seal.

  • Clean the transmission: Before installing the new gasket or seal, we thoroughly clean the transmission and surrounding components. This will ensure that the new gasket or seal will seal properly and prevent any further leaks.

  • Refill the transmission fluid: Once the new gasket or seal is installed and the transmission is reinstalled in the vehicle, we refill the transmission fluid to the proper level and use the correct type of fluid called for your vehicle.

Checking For a Transmission Oil Leak

So what should you do if you suspect your car, truck or SUV has a transmission fluid leak? A few simple things you can do from your driveway to quickly check for a leak is to check the transmission oil level:

  • Check your transmission fluid dipstick

If you suspect a transmission leak, the first diagnosis is checking the dipstick and transmission fluid level. Usually, when checking transmission fluid, the engine should be warm and running. Remove the dipstick, wipe it clean, then re-insert it and check that the fluid level is between the dipstick markers. The fluid should be bright red. Burnt or dark transmission fluid should be replaced. If it needs topping up, make sure not to overfill. Overfilling transmission fluid can actually cause a leak.

  • Check underneath your car for reddish brown fluid

Another simple diagnosis of leaking transmission fluid is checking the ground for oil spots beneath the vehicle. If you notice (fresh) oil spots, check all engine fluids to ensure all oil levels are topped up.

  • Check for dashboard warning lights

Another visual inspection to check for an oil leak is your dashboard warning lights. Any potential  issues with your vehicle including low fluid, may illuminate a transmission light or engine light. If a warning light comes on, its a good idea to visit us for diagnosing the check engine light for a transmission oil leak and fix the problem. If a quick inspection determines low transmission fluid or a transmission fluid leak, the next step is to determine where the transmission oil is leaking from and the extent of repair.


What Are Some Signs Of Transmission Repair?

There are several symptoms that could indicate that you need a transmission repair. One of the most common signs is difficulty shifting gears. This could manifest as a delay in shifting or a grinding noise when you shift gears.

Another sign that your transmission may need repair is slipping gears. This happens when your car's transmission slips out of gear while you're driving. You may notice that your car is struggling to accelerate or that the engine is revving but the car isn't moving forward as quickly as it should.

Another symptom of transmission trouble is leaking fluid. If you see a red or brown fluid under your car, it could be a sign that your transmission is leaking. You may also notice a burning smell coming from your car, which could indicate that the transmission fluid is overheating.

If you experience any of these symptoms, it's important to have your transmission checked at our shop as soon as possible. Delaying transmission repairs can lead to more serious and costly problems down the line.


What's Involved In Transmission Repairs (Process)

Transmission repair is a complex and intricate process that involves diagnosing and fixing issues within the transmission system of your vehicle. Here's an overview of what's involved in transmission repair:

**1** Transmission Diagnosing: The first step in transmission repair is diagnosing the issue. Experienced mechanics use diagnostic tools to assess the transmission's performance, often including a computerized scan to identify electronic problems. They also perform a visual inspection to check for external leaks or signs of damage.

**2** Transmission Fluid Check: Transmission fluid is crucial for proper functioning. Mechanics will check the fluid level and quality. Low or contaminated fluid can indicate a problem within the transmission system.

**3** External Transmission Inspection: The transmission, along with related components like the torque converter and clutch, is inspected externally for signs of damage, leaks, or wear.

**4** Internal Transmission Inspection: If the issue isn't apparent externally, the transmission might need to be disassembled for an internal inspection. This involves removing the transmission from the vehicle and dismantling it to identify damaged or worn-out parts.

**5** Transmission Replacement Parts: Faulty or worn-out components such as gears, bearings, seals, or the torque converter might need replacement. Skilled mechanics identify the damaged parts and replace them with new or rebuilt components.

**6** Transmission Reassembly: After replacing the damaged parts, the transmission is reassembled. Precision is crucial during reassembly to ensure all components are properly aligned and functioning together.

**7** Reinstalling The Transmission: The repaired transmission is installed back into the vehicle, and all the connections, including the driveshaft and axles, are properly reattached.

**8** Transmission Fluid Refill: Clean and proper transmission fluid is refilled to the recommended level. Quality transmission fluid is essential for cooling, lubrication, and smooth shifting.

**9** Testing: The vehicle is taken for a test drive to ensure the transmission functions correctly. Mechanics pay attention to gear shifting, responsiveness, and any unusual noises or vibrations.

**10** Post-Transmission Repair Inspection: After the test drive, a final inspection is conducted to check for leaks, unusual sounds, or any signs of malfunction. Adjustments are made if necessary.

**11** Customer Consultation: The mechanic discusses the repair process, the parts replaced, and any maintenance tips with the vehicle owner. They may also recommend regular transmission service to prevent future issues.

Transmission repair is a specialized task best handled by our professionals. It requires technical expertise, diagnostic tools, and a keen understanding of the intricate workings of the transmission system to ensure a successful repair and the optimal performance of your vehicle.


Transmission Rebuild & Replacement

Transmission rebuilds and replacements are two options that vehicle owners can consider when faced with transmission problems. Both options have their own advantages and disadvantages, and the better option depends on the specific circumstances of the vehicle and the owner's needs and preferences.

A transmission rebuild involves disassembling the transmission, inspecting all the parts, and replacing any worn or damaged parts. The transmission is then reassembled and tested to ensure it functions properly. This option is typically less expensive than a complete transmission replacement, and it can often extend the life of the transmission.

The advantage of a transmission rebuild is that it can often be done more quickly than a complete replacement. It also allows the owner to keep the same transmission that came with the vehicle, which can be important for those who value originality or want to maintain the vehicle's historical value.

On the other hand, a transmission replacement involves completely removing the old transmission and installing a new one. This option is typically more expensive than a rebuild, but it provides the owner with a new transmission that is likely to last longer than a rebuilt one.

The advantage of a transmission replacement is that it can provide a more reliable and long-lasting solution, especially if the old transmission was severely damaged or had a significant number of worn or damaged parts.

Additionally, a replacement transmission may come with a warranty, providing added peace of mind for the owner.

Ultimately, the decision to rebuild or replace a transmission at our shop depends on the specific circumstances of the vehicle and the owner's needs and preferences.


Is a Transmission Rebuild Worth It?

A transmission rebuild may be a good option for those on a tight budget or those who value originality or historical value.

A transmission replacement may be a better option for those who prioritize reliability and long-term performance. Talk with our garage today to determine which option is best for your vehicle.


Is a Transmission Rebuild Better Than a Used Transmission?


The decision to install a used transmission versus a rebuilt transmission considers the age, use and warranty of the used transmission.

You never really know how the used transmission was "driven" and when that used transmission will eventually need a rebuild?

Effectively an overhaul is a transmission rebuild. Replacing everything old and worn to fresh new parts.

The transmission casing is generally the only original remaining part of a transmission rebuild. Assuming the transmission casing is in good condition, all internal parts that perform the function of your transmission will be replaced and overhauled with new parts.

The cost of a transmission rebuild varies versus a used transmission replacement. However, when you rebuild the transmission you can be sure the internal parts have been replaced rather then installing a used transmission that may begin to fail.

Ultimately it depends on the vehicle owners preference, budget and how much longer you will own the vehicle.


Avoiding Premature Transmission Repairs & Rebuild

In order to prevent transmission problems and avoid costly transmission repair, it's important to be aware of the unique terrain and weather conditions of the area and varied landscape, including hills which can put extra strain on your transmission.

Additionally, the city's roads are known to have potholes that can damage your transmission if hit too hard. Be especially careful in inclement weather conditions, such as heavy rain or snow, as they can also affect your transmission's performance.

If you experience any unusual sounds or sensations while driving on major highways like the 400 series highways in these conditions, it's important to get your transmission checked as soon as possible to prevent further damage.

During winter months, roads are often salted to melt ice and snow, particularly on major roads and highways. While this can help with driving conditions, it can also cause corrosion on your transmission over time. 

Be sure to regularly wash your car to remove any salt buildup and keep an eye out for signs of corrosion on your transmission. By taking these precautions, you can prolong the life of your transmission and avoid the need for costly repairs.
