 And Gets You a Better Product

A man is working on the rear differential of a jeep wrangler.

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? Let’s Talk
If you’re hearing whining, clunking, or feeling binding in your drivetrain — don’t wait. Differential problems tend to get worse (and more expensive) the longer they go unchecked.

Give us a call or stop by Superior Transmissions and Auto. We’ll diagnose the issue, walk you through your options, and let you know if a rebuild is the best move. Chances are, it will save you money and get you back on the road with confidence.

What’s Really Going On If you own a Ford Focus—especially a model from 2012 to 2018—you’ve probably heard the words “transmission issue” more times than you’d like. The heart of most complaints? The DTC, or Dual-Clutch Transmission. At Superior Transmissions & Auto, we see these often and know exactly what makes them tick—and what makes them fail. What is a DTC Transmission, Anyway? DTC stands for Dual-Clutch Transmission. Think of it as a hybrid between a manual and an automatic transmission. It has two clutches—one for odd gears and one for even gears—allowing for faster, smoother gear shifts (in theory). It’s designed for fuel efficiency and performance, but in real-world driving, it often feels anything but smooth. Unlike a traditional automatic that uses a torque converter, the DTC in the Ford Focus behaves more like a computer-controlled manual transmission. It can feel jerky at low speeds, hesitate when shifting, or seem like it’s slipping—especially in stop-and-go traffic. Why the Ford Focus DTC is So Problematic The biggest issues with these transmissions usually boil down to the clutch system and internal actuators. In many cases, the vehicle will: Shudder on acceleration Struggle to find or hold a gear Flash the "Transmission Hot" warning Show DTC codes (diagnostic trouble codes) for clutch actuator failure or internal gear ratio errors Ford has acknowledged many of these problems through service bulletins and extended warranties—but even those come with limits. How We Handle Ford DTC Transmissions At Superior Transmissions & Auto, we don’t just throw parts at these issues. We diagnose them thoroughly to pinpoint exactly what’s going on. Often, the root cause is worn or contaminated clutch packs, failed shift actuators, or broken internal components in the TCM (Transmission Control Module). Here’s how we handle DTC repairs: 1. Complete Diagnostic Scan We start with a full scan of the transmission’s computer to identify stored trouble codes. This gives us insight into clutch position, actuator performance, and gear engagement. 2. Clutch Replacement The most common repair is replacing the dual-clutch assembly. These clutches wear prematurely, especially in traffic-heavy areas. We use upgraded parts and take the time to properly recalibrate everything during reinstallation. 3. Actuator & TCM Checks We test the transmission’s shift actuators and often recommend replacement if there are engagement issues or hesitation. In some cases, the TCM may also need programming or replacement. 4. Adaptive Relearn & Road Testing Once the repair is complete, we perform an adaptive relearn procedure and extensive road testing to ensure the transmission shifts correctly under all driving conditions. A Different Drive—And a Different Kind of Fix Driving a DTC-equipped Focus isn’t like driving a standard automatic—and that’s part of the confusion for many drivers. It’s normal for the car to feel a little “clunky” at low speeds. But grinding, slipping, or delayed shifts? Those are not normal. If you’re dealing with a misbehaving Focus transmission, don’t just live with it. And don’t let someone tell you “it’s just how they drive.” We’ve rebuilt countless DTCs, replaced dozens of clutches, and know these systems inside and out. Bring It to the Experts Not every shop will work on DTCs—some won’t touch them at all. At Superior Transmissions & Auto, we specialize in them. Whether you need a diagnostic, a clutch replacement, or a complete rebuild, we’ve got the tools, training, and experience to get your Focus back on the road—the right way. �55357;�56525; Located in New Windsor, NY �55357;�56507; Schedule your appointment right on our website! �55357;�56615; Trust the shop that knows transmissions inside and out.

Why That Matters for Your Car At Superior Transmissions & Auto, we’re proud to say we’re the only shop in the area that rebuilds Continuously Variable Transmissions (CVTs) — and that’s not just a cool brag. It speaks volumes about our experience, our commitment to our craft, and the level of trust you can place in us when your vehicle needs serious work. What Even Is a CVT? A CVT (Continuously Variable Transmission) is not your average transmission. Unlike traditional automatic or manual transmissions, which have a fixed number of gears, a CVT doesn’t have gears at all. Instead, it uses a system of pulleys and a steel belt to provide a seamless range of gear ratios. This allows for smoother acceleration, improved fuel efficiency, and a more consistent driving experience. Sounds great, right? It is — until something goes wrong. Why Most Shops Don’t Touch CVTs Here’s the thing: CVTs are a completely different animal than standard automatics. Rebuilding one isn’t just a matter of replacing worn-out clutches or seals. You need specialized tools, diagnostic software, and, most importantly, in-depth knowledge of how each specific CVT design works — and they vary a lot between manufacturers like Nissan, Subaru, Honda, and Toyota. Most general repair shops — even ones that dabble in transmissions — will tell you flat-out: “We don’t rebuild CVTs.” Why? Complex internals: CVTs rely on precise hydraulic and electronic controls. One wrong move and it’s toast. Lack of training: Most techs aren’t trained in CVT rebuild procedures, especially since many manufacturers don’t even sell internal parts. Special equipment required: You can’t rebuild a CVT with just a socket set and a transmission jack. The tools alone are a barrier. OEM discouragement: A lot of manufacturers push for full replacement instead of repair — leading shops to avoid the risk and effort of a rebuild. Why Superior Can and Does Rebuild CVTs At Superior Transmissions & Auto, we lean into the challenge. We’ve invested in the training, equipment, and expertise to properly rebuild CVTs — and we’ve been doing it successfully. We don’t shy away from complexity — we thrive in it. When other shops say, “It can’t be rebuilt,” we say, “It just hasn’t been rebuilt here yet.” We’ve rebuilt CVTs that other shops wrote off as scrap. In fact, we’ve had customers towed to us after being told their only option was a brand new transmission or a used junkyard transmission — and we were able to save them thousands by rebuilding instead. Ultimately giving them back a better product. The Bottom Line: CVT Trouble? You Found the Right Shop If your car has a CVT and it’s slipping, shaking, or just not moving, you need someone who knows what they’re doing. We’re not just another shop that “does transmissions.” We are transmission specialists — and more importantly, we’re CVT specialists, which is something you won’t find anywhere else around here. We’re here to do the work that others won’t — and we do it right. Give us a call or schedule an appointment online. If it’s got a CVT, we’ve got you covered.
