Car Gearbox Repair in NJ

Keep Your Shifts Smooth, Reliable & Responsive

Your car’s gearbox—whether automatic or manual—is essential for transferring power from the engine to the wheels. When it starts to malfunction, you’ll notice hesitation, grinding, slipping, or complete loss of drive. A failing transmission can quickly lead to serious damage if left unchecked. Professional gearbox repair restores smooth shifting, protects your drivetrain, and gets you back on the road with confidence.

Signs Your Gearbox Needs Repair

• Delayed or jerky gear changes

• Transmission slipping during acceleration

• Unusual noises like whining, clunking, or grinding

• Burning smell from under the hood

• Leaking transmission fluid (red or brown)

• Check engine or transmission warning light

• Difficulty engaging gears in manual transmissions

If you notice any of these symptoms, your gearbox may be under stress—early repair can save you from a full rebuild or replacement.
