Automatic Transmission

A defective transmission is potentially the worst disruption of your daily driving experience. Keep your transmission maintenanced.

Standard Transmission

The manual transmission is on the endangered species list. Every year fewer and fewer cars are offered with a clutch and a shifter. Why?

4x4 Transfer Case

The heart of an off road 4x4 might be the engine but it’s the transfer case that gets power to the axles!  Find out more on how to get the right one for you.

Differentials & Axles

The differential gearing allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when the vehicle turns.

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 StarsJim Kane
