What Our Customers are Saying about our Transmission Repair Service

Came to Colorado on vacation and our vehicle broke down. We called Brad at High Plains Transmission and he fixed our vehicle quickly and at an affordable price. We got the vehicle back before we left and drove it home safe and sound. Thank you Brad! Five Stars Jim Kane

From Montana

Thank you, Thank you, Thank you! It was so nice finding a shop that not only gave us excellent pricing but was treated us like family. We were given an estimate on the price and a day and time for pick up and it was on the money! Working with High Plains Transmission was a great experience and we will not take our car anywhere else.

Thank you for all your hard work and help with fixing our 95 Mercury. Thank you for fixing the switch that was bad now she runs like a gem!

I have been taking my vehicles to Brad and John at High Plains Transmission for over 6 years now. I will not take my cars anywhere else. I even call them to ask where to take my vehicle for any other repairs too, that they may not service in their shop! I would recommend them to anyone! Taylor Nagao

Brad and his team will be happy to try and give you an estimate over the phone, however bringing your car or truck in is always the best way to get an exact price.
