These guys are SO great. Great job and a great price! My family and I (and even friends that I referred) drive an hour to come to them. They do great work and have excellent customer care! Even when it was closing time they were so kind and helpful, making sure I understood and was satisfied with everything, instead of just rushing me out the door. 100% recommend them!

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.


Take your car here. If you have any transmission 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. The diagnostic is only $90. 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

A transmission service is defined as what exactly?

Repair shops offer transmission repair services to fix or replace worn or broken transmission components. It is crucial to maintain a well-functioning transmission because of its role in regulating the vehicle’s power and speed.

What are the warning signs that my transmission requires attention?

The check engine light may come on, there may be a burning smell, transmission fluid may leak, and shifting gears may be difficult or impossible.

In general, how much does it set you back to fix a transmission?

Whether the transmission needs to be replaced or only repaired can have a significant impact on the final price tag, as can the brand and model of the vehicle. Minor fixes may cost a few hundred dollars, while a full replacement may cost several thousand.

How long does transmission repair typically take?

The time it takes to fix a transmission depends on factors like the nature of the damage and the accessibility of replacement parts. It could take a few hours to conduct minor repairs, but it could take several days to replace or repair key components.

Should I spend the money to fix my car’s transmission or just get a new vehicle?

There are a number of variables at play here, including the car’s age, its condition, its value in the market, and the price of the transmission repair. It may be more cost-effective to purchase a new or used vehicle rather than undertake a costly repair.

In the future, how can I avoid transmission issues?

Transmission failure can be avoided with regular maintenance. Changing the transmission fluid on a regular basis, using the right sort of transmission fluid, and keeping an eye on how your car performs are all part of this maintenance.

Can you get around with a broken transmission?

If your transmission is acting up, you shouldn’t be behind the wheel. It’s risky and could do even more harm to the car.

Can I do the transmission repair by myself?

Repairing a transmission is often difficult and calls for technicians with certain training and equipment. Professionals should handle any significant repairs or replacements, but a savvy do-it-yourself kind of person may be able to handle minor issues.

In comparison to a complete replacement, what happens during a transmission rebuild?

Rebuilding entails disassembling the transmission, replacing any worn or broken parts, and reassembling the unit. However, when you opt for a replacement, the complete transmission is taken out and a new or refurbished one is installed in its place.

Does transmission life extension depend on frequent maintenance?

In a word, yes. Transmissions last longer and drive better when they are serviced regularly, and that includes having the fluid changed as directed by the manufacturer.
