The right diagnosis changes everything.

Not every transmission concern requires a rebuild.

That's why every Tuesday and Thursday from 2:00–4:00 PM, our team offers a Complimentary Transmission Scanning & Assessment.

We'll take the time to understand what your truck is telling us, explain the results, and discuss your options; because informed decisions begin with accurate diagnostics.

No pressure. No obligation. Just expert guidance from a team dedicated to doing things the right way.

Confidence isn't written on paper. It's built into every transmission we assemble.

A warranty is important, but it's only one part of the story.

At Tier One Transmissions, we believe confidence starts long before a transmission ever leaves our shop. It starts with premium components, meticulous assembly, rigorous inspection, and testing every unit to meet the standards we'd expect for our own trucks.

Because standing behind our work isn't just a policy.

It's the standard we build to every day.

This is why we do what we do!

Every transmission has a story.
Every customer does too.

When this customer came in after a turbo failure, they expected a stressful repair.

Instead, they got:
✔ An honest diagnosis
✔ Clear explanations
✔ Options that fit their budget
✔ No pressure to buy upgrades they didn't need
✔ Fast turnaround

That's exactly how we believe truck repair should be.

Reviews like this remind us that doing the right thing still matters.

Thank you for trusting Tier One Transmissions.

Ever wonder what actually happens inside an automatic transmission? Or why certain parts fail while others last for hundreds of thousands of miles?

We put one of our builders in the hot seat for a round of rapid-fire questions to break down transmission concepts in a way that's easy to understand.

No sales pitch. Just real answers from the people who build them every day.
