About Our Shop

Rooted in Gypsum. Built on Trust.

McKim Service & Transmission has been a cornerstone of the Gypsum automotive community for over two decades. What started as a one-bay operation has grown into a full-service repair center — but the philosophy never changed.

We believe every driver deserves a mechanic who explains the problem in plain language, recommends only what's actually necessary, and stands behind every repair with a fair price. That's the standard we set every day.

Why McKim

The Difference Is in the Details

We've earned the loyalty of Gypsum drivers through consistent, honest service — not through flashy ads or discounts.

No Unnecessary Upsells

We tell you what your vehicle actually needs — not what the manual says it might need someday. If a repair can wait, we'll say so.

Clear Communication

You'll know exactly what's wrong, why it matters, and what it costs before we lift a wrench. No jargon, no hidden fees, no surprises.

Quality Parts, Fair Prices

We source reliable parts and price our labor competitively. Every estimate is written out and approved by you before any work begins.

Local & Accountable

We're your neighbors. We see you at the grocery store, and we care about our reputation in this community. That means we do it right.
