Warning Signs of a Failing Transmission - Act Promptly

Modern transmissions are built to be dependable, yet they can still break down. If your transmission is showing any of these symptoms, it’s time to take action:

Check Engine Light

Transmission problems could be the cause of the check engine light being on.

Strange Noises or Vibrations

The presence of strange vibrations or noises while driving could indicate a problem with the transmission.

Erratic Gear Shifting

A jerky or unexpected shift in gear could be a sign of a gearbox failure.

Transmission Slipping

It could be an indication of transmission slippage if your car’s speed increases significantly but the engine RPM doesn’t.

Delay in Shifting

If your transmission isn’t working properly, shifting from park to drive or any other gear could take longer than usual.

Immediate inspection of the transmission is required in the event that you encounter any of these signs. Ignoring these problems may necessitate more costly repairs in the future.

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!

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
