Narval Mangal

When it comes to automotive engineering, few components are as intricate, vital, or unforgiving as a vehicle's transmission system. Managing complex hydraulic networks, planetary gear sets, and electronic control modules requires far more than basic mechanical skill—it demands deep intuition, exact precision, and decades of focused hands-on experience. For over 35 years, Narval Mangal, the owner and master builder behind Shift Right Transmission & Auto Service in Stockbridge, Georgia, has dedicated his life to mastering this craft. His relentless pursuit of technical excellence and commitment to honest customer care have established Shift Right Transmission as a premier regional service provider and a trusted nationwide source for custom-rebuilt transmissions.



Narval’s journey into automotive repair began long before modern diagnostic scanners and computerized gearshifts dominated the industry. Starting his career over three and a half decades ago, he learned the trade from the ground up, developing a foundational understanding of mechanical principles that can only be earned through years at the workbench. Over the course of his 35-year career, Narval has witnessed the evolution of automotive technology firsthand—transitioning seamlessly from classic hydraulic automatic and manual gearboxes to today's highly complex, multi-speed electronic, CVT, and heavy-duty drivetrain systems. This decades-long perspective gives him a unique diagnostic edge that few technicians possess.

The Craft of a Master Transmission Builder

The title of "Master Builder" is not easily earned in the automotive repair industry. While many general repair shops rely on swapping out failing components with off-the-shelf replacements, Narval specializes in the intricate art of complete transmission teardowns, custom rebuilds, and high-performance recalibrations. A true master builder understands that a successful transmission rebuild requires absolute accuracy down to fractions of a millimeter. Narval approaches every project with microscopic attention to detail, carefully inspecting planetary gears, clutch packs, valve bodies, seals, and torque converters to identify the root cause of component fatigue rather than merely treating the symptoms.

Under Narval’s leadership, Shift Right Transmission & Auto Service has built a reputation for delivering precision-built drivetrains that often outperform factory originals. By utilizing upgraded internal components, addressing known OEM design flaws, and applying advanced diagnostic procedures, Narval ensures that every unit built in his shop is engineered for maximum durability, heat resistance, and seamless gear engagement. Whether servicing a daily driver, a heavy-duty commercial truck, a fleet vehicle, or a classic restoration project, Narval treats every transmission build as a custom piece of precision engineering.

Building Trust Through Honest Auto Service

While technical skill is the backbone of Shift Right Transmission & Auto Service, Narval’s core business philosophy is rooted in honesty, transparency, and personal integrity. Transmission issues can be stressful and overwhelming for vehicle owners, often presenting complex symptoms such as gear slippage, harsh shifting, fluid leaks, delayed engagement, or the check engine light illuminating. Narval takes pride in removing the mystery from transmission repair. He believes in educating his customers, providing accurate diagnostics, clearly explaining necessary repairs, and delivering fair, transparent pricing without high-pressure sales tactics.

This commitment to honest service has earned Narval and the Shift Right Transmission team a fiercely loyal customer base throughout Stockbridge and the surrounding Georgia communities. Local drivers know that when they bring their vehicle to Shift Right, they are receiving straightforward advice from an experienced professional who prioritizes safety, reliability, and long-term performance over quick fixes.
