Welcome to Birchmount Auto Repair — Scarborough's Trusted Mechanic
The transmission is one of the most complex and expensive components in your vehicle — and one of the most important to keep in good working order. At Birchmount Auto Repair, our drivetrain specialists service both automatic and manual transmissions, from routine fluid and filter changes to solenoid replacement and complete transmission rebuilds. We diagnose transmission issues accurately before recommending any repair, ensuring you only pay for what your vehicle actually needs.
Transmission problems left untreated tend to worsen quickly and become significantly more expensive to repair. Early signs like slipping gears, delayed engagement, rough shifts, or transmission warning lights should be addressed promptly. Our technicians perform a thorough diagnostic including fluid inspection, fault code scanning, and a road test evaluation to pinpoint the cause before presenting you with a clear, detailed repair estimate.

Most manufacturers recommend changing automatic transmission fluid every 60,000 to 100,000 kilometres. Some sealed units specify longer intervals, while vehicles used in heavy-duty conditions may need more frequent changes.
