Denver’s Trusted Auto Repair Shop Since 1979

Since 1979, A-Affordable Transmissions Center has built its reputation as a leading auto repair shop in Denver by doing the work most shops send somewhere else. We rebuild and repair complex drivetrain systems in-house. What began as a small transmission rebuilding operation has grown into a full-service facility with two convenient locations serving North and South Denver. Today, our ASE-certified technicians combine decades of hands-on experience with advanced digital inspection diagnostics to deliver accurate answers to solve your vehicle’s problems.

We are known for transmission rebuilds using precision crafted components, but our expertise extends far beyond the drivetrain. From routine car maintenance like replacing a fouled spark plug, to fixing engine performance concerns or suspension problems, we service every vehicle with the same level of care and technical discipline. When you bring your car, truck, or SUV to A-Affordable Transmissions Center, you can expect that we will help prevent unnecessary repairs, keep your vehicle dependable for both daily commutes and extended trips, and deliver the best auto repair experience possible.

With 2 Locations Serving
Both North Denver And South Denver

-Affordable Transmissions Center has Denver’s best repair/rebuild pricing, service, and workmanship. We offer transmission pre-check inspections, including a road test, preliminary testing, and electronic scan. In addition, estimates are provided before work begins, and all repair work done in house. Our local family-owned and operated shop has two convenient locations in Englewood and Thornton serving both North Denver and South Denver area drivers.

Advanced Transmission, Transfer Case, Clutch & Differential Repair

When your vehicle needs advanced drivetrain and transmission repair, experience matters. Our ASE-certified technicians and dedicated transmission builders specialize in just that. We diagnose and repair complex automatic and manual transmission systems, transfer cases, clutches, and differentials. Because these are not routine car maintenance services, they require precision, technical training, and a deep understanding of how your vehicle’s powertrain operates.

With seasoned auto mechanics and specialized transmission builders at both our Englewood and Thornton locations, we deliver the kind of expertise most general auto repair shops simply do not offer. From passenger vehicles to medium-duty trucks, RVs, and work vehicles, our A-Affordable Transmissions Center team fixes transmission problems the right way, the first time.

Advantages of regular transmission and vehicle maintenance:

A-Affordable Transmission Centers specialize in transmissions, transfer cases, clutches and differentials. Because we specialize in these services, we also understand the importance of regular transmission service and overall auto repair maintenance to prolong the life of your vehicle and reduce the occurrence of costly repairs.

Minimizes wear and tear:

By preventing overheating and maintaining clean and contamination-free fluid, regular transmission service and routine vehicle maintenance reduces the strain on the components, extending their lifespan.

Enhances gear function:

Regular transmission service and proper vehicle maintenance contribute to improved gas mileage, optimizing the performance of your vehicle’s gears.

Improves fuel efficiency:

Unaddressed transmission problems can increase fuel consumption. Through seamless car engine and transmission operation, regular service helps improve fuel efficiency and reduce fuel consumption during daily driving and highway trips.

Saves money on repairs:

By reducing fuel efficiency drains and improving overall performance, regular transmission service and preventative vehicle care prevents costly repairs and replacements in the future, leading to significant cost savings.

Extends vehicle life:

Regular transmission service and routine maintenance result in smoother shifting and extend the lifespan of your vehicle’s major systems, reducing the need for premature replacements.

 

Prevents unnecessary repairs:

Routine inspections and scheduled maintenance help identify minor concerns before they become major failures, preventing unnecessary repairs and expensive replacements.

Maintains overall car performance:

Besides benefiting the transmission, regular service also supports other vital components such as the engine and exhaust system, ensuring your car runs smoothly.

Enhances road safety:

Neglecting transmission maintenance or general vehicle maintenance can lead to system failure and expensive repairs, jeopardizing your safety on the road. Regular service helps avoid such risks.

Prevents engine lock-up:

Regularly having your car checked by an experienced technician safeguards your vehicle from accumulating damage, including the possibility of engine lock-up.

Devin is an absolute professional. You can tell that these guys are serious about what they are doing, and offer an exceptional price for the outstanding service they provide. I had all my questions answered, and my car runs great now!

Deriruh Vsqz

Randy and his crew are amazing. After 5 shops and mechanics wrongfully diagnosing my car “fixing it” and it still making the same clunking noise I decided to give this shop a shot. They fixed my issue promptly and my car is running like it’s brand new again. I’ll never trust anyone else with my Subaru other then Randy and his team.

Seth Hughes

Hello, had the transmission in my 66 Ford Fairlane rebuilt in October 2021. Nearly 2 years later still working great no leaks shifts just as nice as it did when I picked it up. Great customer service after the rebuild would totally recommend.

Michael

Take your car here. If you have any transmission, or gearbox issues this is the absolute best transmission shop you will find in Denver. My cars transmission lost reverse gear, and had a slew of other issues going on internally that I didn’t even know about, requiring a complete transmission rebuild. Devin was absolutely phenomenal, and let me know everything that was happening during the entire service. These guys absolutely stand by their word, and work. With 250k miles, I have a rebuilt engine with 50k miles on it, and now a new, rebuilt transmission. Flawless. Another 4×4 lives another day. Drives smoother than ever. Thank you guys!

Cody Dent

Brought my 08 pontiac grand prix for a rebuild of the transmission, car was done within two days of dropping it off and the price quoted was correct and affordable (for a transmission rebuild) the shop is very professional and knowledgeable also friendly and don’t make you feel dumb or belittle you for asking questions. Also check back in with you on their work a week or two later. Would definitely return to these guys for any transmission work I’ll need on any of my vehicles and will always recommend them to friends, family and anyone needing work done. Thank you guys!!

Eleanore Thayer

I can not rave enough about thus place. Randy and his team are fast, friendly, and KNOW what they are doing! I had my clutch replaced here after being less than happy with another company doing it twice and blowing it both times in two years… This team is transparent and care about the quality of their work. If you need transmission work or your clutch replaced, this is your company. They made my Subaru ready for the road and I couldn’t be happier! 10/10 tldr: use this company and you will be a happy camper

About Us

A-Affordable Transmission Center has been a trusted name in Denver since 1979, proudly serving drivers from two convenient locations in South Denver and North Denver.

The business began in 1979 when the original owner started rebuilding transmissions out of his home to help people keep their vehicles safe and on the road longer. Ron Shaw took over in 2002, continued the tradition of rebuilding transmissions in-house, and grew the company with help from his two sons. The current owners purchased the shop in 2022, kept the well-known name, added general repair, and still rebuild about 98 percent of transmissions in house. Their focus remains the same as it has from the beginning, to help Denver drivers protect their vehicles, avoid long repair delays, and feel confident in the safety and reliability of their car or truck.
