A Passion for Gearbox Engineering

Miernik Auto Service was born from a deep passion for automotive mechanics and decades of dedicated experience in repairing automatic transmissions.

Like a Mechanism in a Swiss Watch

From the very beginning, we committed ourselves to a single specialization — because we firmly believe that only by focusing on what we do best can we achieve the highest standard of quality.

For us, repairing automatic transmissions is not merely a job. It is a true craft that demands deep technical knowledge, extreme precision, and immense responsibility. We treat every single gearbox like a mechanism in a Swiss watch — every component, tolerance, and hydraulic channel must function flawlessly.

Over the years, we have built practical experience that today allows us to diagnose even the most complex mechanical and electronic faults and resolve them definitively. Behind us are over 1,000 repaired gearboxes and hundreds of satisfied motorists who return to us because they know they can rely on our honesty.

Reliability, Quality & Honesty Towards the Client

In our daily work, three fundamental principles guide everything we do: reliability, quality, and complete honesty towards every client who entrusts their vehicle to us.

We execute every repair with the utmost diligence, relying on advanced diagnostic equipment and genuine, proven components. We never cut corners — because we know that the safety, smoothness, and driving comfort of your vehicle depend entirely on the integrity of our work. That is why we provide a written 6-month warranty on all our completed repairs: because we stand with complete confidence behind the quality of our craftsmanship.
