Complete Mechanical Repair in Missoula

Your vehicle's mechanical health depends on accurate diagnostics and experienced hands. Whether you're navigating Reserve Street traffic or climbing the switchbacks into the Rattlesnake, the demands placed on your engine, transmission, and drivetrain are real—and they require attention from someone who understands what's happening beneath the surface.

Auto Assist Co. brings 25 years of hands-on mechanical expertise to every job, from diagnosing misfires to addressing complex drivetrain concerns across domestic, foreign, European, and classic vehicles. Montana's extreme seasonal temperature swings place considerable stress on oil viscosity, gasket integrity, and component expansion rates—factors that inform every repair decision made in the shop.

Led by a 7th-generation Montana owner and a multigeneration local technician, the team understands how Missoula's winter cold snaps and summer heat cycles affect vehicle performance. You receive transparent evaluations, precision repairs, and no unnecessary upsells—just the work your vehicle actually needs.

Missoula's geography and climate create unique wear patterns. Vehicles driven through the South Hills face steep grades that stress cooling systems and brakes, while those commuting along I-90 experience sustained highway speeds that reveal underlying mechanical weaknesses. Stop-and-go traffic on Reserve Street can generate heat buildup in automatic transmissions, accelerating fluid degradation and internal wear.

The shop's approach is rooted in dealership-level diagnostics combined with independent shop flexibility. Tools and techniques developed across machining, custom builds, and factory environments ensure that your repair is completed correctly the first time. From timing belt replacements to cylinder head work, every service is performed with precision and accountability.

If you've noticed rough idling, reduced power, or unusual sounds, don't wait for a minor issue to become a costly breakdown. Call us today at your earliest convenience for Complete Mechanical Repair in Missoula.

Whether you drive a European sedan, a classic pickup, or a modern hybrid, your vehicle benefits from service that addresses the root cause—not just the symptom. Here's what sets this approach apart:
