Your Reliable Transmission & Auto Repair Shop in New Windsor, NY

At Superior Transmissions and Auto, we’ve built our reputation on doing the job right — especially when it comes to drivetrain components like differentials. One question we hear a lot is, “Why rebuild a differential when I could just replace it?” Short answer: Rebuilding saves you money, gets you a better-quality product, and ensures the job is done to your vehicle’s exact needs. And the best part? We handle the entire rebuild in-house, from teardown to final torque specs — so you get expert-level work without the markup. Let’s break it down. 1. Cost Savings You Can Actually Feel A brand-new differential from the dealer can cost thousands — and that’s before labor. Many of those new units are mass-produced and may include components you don’t even need. By rebuilding your existing differential, we focus on fixing exactly what’s worn, saving you hundreds (and in some cases, well over a thousand dollars) while keeping the core housing and gears that are still in great shape. When we rebuild, we replace critical components like: Bearings Seals Shims Worn-out gears (when needed) You’re only paying for what’s necessary — no more, no less. 2. A Better Product Than Many "New" Replacements Rebuilt in-house doesn’t mean compromised quality. Quite the opposite. Many aftermarket or remanufactured differentials are rebuilt in bulk with low-cost parts, questionable tolerances, and minimal testing. At Superior, we rebuild each differential to precise factory specs using high-quality, OEM-grade or better components. That means: Hand-fit clearances Precision gear setup Proper break-in procedures Final torque and preload checks before it goes back in your vehicle We know exactly what went into your rebuild — because we did it ourselves, right here in our New Windsor, NY shop. 3. In-House Means Faster Turnaround and Better Accountability When we rebuild your differential in-house, there's no waiting on third-party suppliers or guessing what's been done behind closed doors. We walk you through the diagnosis, show you the wear and tear, and explain exactly what parts are going in. Plus, if something ever needs rechecking, we already know the history — and we stand behind our work. 4. Built for Your Driving Needs Whether you’re driving a work truck, a family SUV, or a weekend performance car, we tailor each rebuild to your use case. Need a stronger setup for towing? Quiet operation for long highway drives? A better gear ratio for off-roading? We can make it happen — right here. Need a Rear Differential Rebuild?
