The Transmission Rebuild Process

Rebuilding a transmission is a skillful blend of technical precision and deep automotive knowledge. At Miramar Transmission, we’ve spent over 30 years perfecting this craft, ensuring that every transmission rebuild we undertake restores vehicles to their peak performance. In this comprehensive guide, we’ll walk you through the transmission rebuild process, discuss the benefits of rebuilding versus replacing, and explain why trusting experienced technicians is crucial for a successful rebuild.

Step 1: Comprehensive Diagnostic Evaluation

Before any work begins, we start with a thorough diagnostic evaluation. Our certified master transmission technicians use advanced tools to assess the transmission’s condition, identifying issues such as slipping gears, overheating, or delayed shifting. This ensures that every potential problem is diagnosed, so nothing is left to chance.

Rob H. from San Francisco had a sluggish and stuttering 2001 Toyota 4Runner SR5. Our diagnostic evaluation revealed transmission issues causing these problems. After the necessary repairs, Rob’s 4Runner was back to driving like a dream.

Step 2: Transmission Removal and Disassembly

Once we’ve identified the issues, we carefully remove the transmission from the vehicle. This step is critical and must be done with precision to avoid causing further damage. After removal, the transmission is disassembled, and each component is inspected. We pay close attention to parts like clutch plates, bands, and bearings, determining which components need to be replaced.

Len S. from Poway faced persistent transmission error codes in his 2013 BMW 328i. Despite taking the car to a dealership, the issue couldn’t be reproduced. Len turned to us for a second opinion, and during our disassembly process, we were able to reproduce the error and identify the root cause—a computer issue affecting the transmission. Our team isolated and fixed the problem, ensuring Len’s BMW continued to run smoothly for years to come.

Step 3: Cleaning and Component Replacement

After disassembly, all parts are meticulously cleaned to remove debris and contaminants. This step ensures that no foreign material compromises the rebuilt transmission. We replace any worn or damaged components with high-quality new or reconditioned parts, including gaskets, seals, torque converters, and solenoids.

We thoroughly cleaned and replaced the necessary components, ensuring the Mustang was in top condition. After the repairs, the Mustang drove like new, and Eriks was so impressed with our service that he highly recommended us to others.

Step 4: Precision Reassembly

Once all components have been cleaned and replaced, the transmission is carefully reassembled. This step requires a high level of precision, as each part must be installed according to strict manufacturer specifications. During reassembly, the transmission control module may also be reprogrammed to ensure it functions seamlessly with the rebuilt transmission.

Sam R. from San Fernando brought his 2007 Ford Explorer to us after another shop misdiagnosed a transmission issue. Frustrated by the incorrect diagnosis, Sam sought a second opinion from Miramar Transmission. Our team carefully disassembled and reassembled the transmission, correcting the initial mistakes and ensuring the Explorer ran smoothly. Sam was so pleased with the result that he declared Miramar Transmission the best shop he had ever taken his vehicles to.

Step 5: Rigorous Testing and Quality Control

Before the rebuilt transmission is reinstalled, it undergoes rigorous testing. This includes bench tests and road tests to ensure that the transmission shifts smoothly, responds correctly, and shows no signs of slipping, overheating, or other issues. We’re committed to meeting or exceeding factory standards, so every rebuilt transmission is thoroughly vetted before it goes back into the vehicle.

Brice C. from San Francisco had a blown solenoid on his 2014 Subaru WRX. After hearing about our reputation for quality service, Brice brought his WRX to us for a full rebuild. Our rigorous testing process ensured that the transmission was rebuilt to the highest standard, and Brice was thrilled with the result. Not only did his WRX run perfectly, but our team also went above and beyond by detailing his car, leaving Brice eager to recommend us to friends and family.

Step 6: Reinstallation and Final Inspection

The final step involves reinstalling the transmission into your vehicle and performing a thorough final inspection. After reinstallation, we conduct another road test to ensure everything is operating as it should. This last check guarantees your transmission rebuild is complete and your vehicle is ready for the road.

Daniel W., a car enthusiast from San Diego, came to us after another shop left his Jeep with a whining transmission following a service. Skeptical of most repair shops, Daniel was pleasantly surprised by our expertise and professionalism. After we corrected the issues during the reassembly and testing phases, Daniel’s Jeep now runs flawlessly, and he has become a loyal customer, praising our exceptional service.

Why Choose a Transmission Rebuild?

Choosing to rebuild your transmission rather than replace it offers several significant advantages. For one, it’s often more cost-effective. While a new transmission can be expensive, especially for older or specialized vehicles, a rebuild allows you to retain your original unit, replacing only the parts that are worn out. This approach can save you a substantial amount of money without compromising on quality.

Rebuilding also helps preserve your vehicle’s value. Maintaining the original transmission, especially in classic or high-performance cars, is important for keeping the vehicle’s performance characteristics intact. Plus, during a rebuild, there’s also the opportunity to make performance enhancements, such as upgrading to stronger components that can better handle your driving needs.

The Value of Expert Technicians

Transmission rebuilding is not a job for just any mechanic—it requires specialized knowledge, experience, and precision. At Miramar Transmission, our certified master transmission technicians bring over 30 years of expertise to every rebuild. We use advanced diagnostic tools and adhere to strict procedures to ensure each transmission we rebuild is restored to like-new condition.

Parissa S. from Los Angeles faced a significant challenge when her BMW’s transmission failed. She turned to us, and our expert team immediately took action to fix the problem. Parissa was particularly impressed with our communication and the detailed care we provided, which even included detailing her car’s interior and exterior. She left with a smooth-running vehicle and a positive experience that exceeded her expectations.
Roger W. from San Diego brought his vehicle to us for a range of services, including transmission repair, a rebuilt engine, and an oil change. He was thoroughly impressed by our team’s knowledge, honesty, and dedication. Roger noted how our technicians treated his vehicle with care and precision, making him a loyal customer who now recommends Miramar Transmission for all automotive repair needs.

Frequently Asked

How often should I have my transmission serviced?

For nearly every economy class vehicle, we recommend servicing your transmission once per year or every 15,000 miles. These metrics will vary slightly depending on your particular transmission model, as well as other factors such as if you are/plan on towing, or if you are using the vehicle in extreme conditions, like off-roading. If you are unsure if our recommended metrics fit your vehicle, feel free to call us and ask!

Is it better to rebuild or replace a transmission?

Rebuilding a transmission is often more cost-effective than replacing it, especially if the vehicle is in otherwise good condition. A rebuild allows you to retain the original transmission, which is typically better suited to your vehicle’s overall performance and can be less expensive than a full replacement. However, in cases of severe damage where multiple major components have failed, replacing the transmission might be the more viable option. At Miramar Transmission, we can help you weigh the pros and cons of each option based on your specific situation.

What’s the difference between a transmission rebuild and a remanufacture?

A transmission rebuild involves disassembling and repairing the existing transmission, replacing only the parts that are worn or damaged. In contrast, a remanufacture typically involves completely rebuilding the transmission to factory specifications using both new and reconditioned parts, and it may be done by the original manufacturer or a third-party remanufacturer. While both processes aim to restore the transmission to like-new condition, remanufactured transmissions are often available off-the-shelf, which can be a quicker option than waiting for a custom rebuild.

Could hard shifting be fixed without a full rebuild?

Yes, a faulty sensor can cause hard shifting by sending incorrect signals to the transmission. This can often be an easy fix, and our free diagnostic check will help pinpoint if a sensor is the culprit.

How can I tell if my transmission needs a rebuild?

Signs that your transmission may need a rebuild include slipping gears, overheating, unusual noises (such as grinding or whining), delayed or erratic shifting, and transmission fluid leaks. If you notice any of these symptoms, it’s essential to have your transmission evaluated by a professional as soon as possible. A thorough diagnostic evaluation will determine whether a rebuild is necessary or if a simpler repair might suffice.

How long does the free diagnostic check take?

The diagnosis process takes 15 minutes on average. If you make an appointment, you can expect the entire process from checking in your vehicle to completing the diagnosis to take no longer than 20 minutes. For walk-ins, the wait time may be longer depending on the technicians' workload that day.

How do I know if my transmission fluid needs to be changed?

Signs that your transmission fluid may need to be changed include dark or dirty fluid, a burning smell, delayed shifting, and unusual noises. If you notice any of these signs, it's important to have your transmission checked by a professional.

How long does a transmission rebuild take?

Typically, a transmission rebuild can take anywhere from 3 to 5 days, depending on the complexity of the job and the availability of parts. Our team at Miramar Transmission strives to complete every rebuild as efficiently as possible without compromising on quality. We understand that being without your vehicle can be inconvenient, so we work diligently to get you back on the road quickly while ensuring that the job is done right the first time.

What happens if I don't change my transmission fluid?

Failing to change your transmission fluid can lead to increased wear and tear on your transmission, overheating, and eventually, transmission failure. Regular fluid changes are essential to prevent these issues and keep your transmission running smoothly.

Can I change my transmission fluid myself?

While it is possible to change your transmission fluid yourself, it’s often best to have it done by a professional. This ensures that the fluid is changed correctly, the old fluid is properly disposed of, and any potential issues with your transmission are identified and addressed.

Is a transmission fluid flush the same as a fluid change?

A transmission fluid flush involves removing all the old fluid and replacing it with new fluid, while a fluid change typically involves draining the old fluid and replacing only a portion of it. A flush is more thorough but may not be necessary in all cases. Consult with a professional to determine the best option for your vehicle.

Can transmission slipping be fixed without a rebuild?

Yes, transmission slipping can sometimes be fixed without a full rebuild, depending on the cause. Issues like low transmission fluid, worn-out solenoids, or minor component wear can often be addressed with targeted repairs. However, if the slipping is due to severe internal damage, a rebuild may be necessary.

Can a simple fluid change fix transmission slipping?

In some cases, a simple transmission fluid change can resolve slipping issues, especially if the fluid is low or degraded. It's an affordable first step, and our free diagnostic check can help determine if this is the right solution for your vehicle.

Is transmission noise always a sign of major damage?

Not necessarily. Unusual noises can sometimes be due to minor issues like loose components or worn-out fluid. Our free diagnostic check can help identify if the noise is caused by something simple.
