ACE Transmission is Springfield’s dedicated transmission specialist — not a general mechanic who also does transmissions. Since 1981, we’ve focused exclusively on transmission repair, rebuilds, and service for all makes and models. Most jobs are completed in 1–3 days, every repair is backed by a 3-year unlimited mileage warranty, and you’ll always get a straight answer before we touch your vehicle.

Transmission Services We Offer

ACE handles the full range of transmission work — from routine fluid service to complete rebuilds and remanufacturing.

Transmission Repair

If your transmission is slipping, shuddering, hesitating, or throwing a code, our specialists diagnose the exact problem before recommending any repair. We don’t guess. We use dedicated transmission diagnostic equipment to pinpoint the issue — whether it’s a solenoid, a worn clutch pack, a valve body problem, or something else entirely. Most transmission repairs are completed in 1–3 business days.

Transmission Rebuild

When a transmission is too far gone for a targeted repair, a rebuild is often the most cost-effective path forward — and significantly less expensive than a dealer replacement. Our technicians disassemble, inspect, clean, and reassemble your transmission with quality parts, new seals, and rigorous testing before it goes back in your vehicle. Every rebuild comes with our 3-year unlimited mileage nationwide warranty.

Transmission Remanufacturing

ACE has on-site remanufacturing capabilities — we don’t just swap parts, we rebuild transmissions to factory spec or better. This matters when you’re dealing with a high-mileage vehicle or a transmission with known design issues. A properly remanufactured transmission is more reliable than a used unit and far less expensive than a new OEM replacement.

Transmission Fluid Service

Transmission fluid breaks down over time, losing its ability to lubricate, cool, and protect internal components. A fluid service — drain, flush, and refill with the correct fluid type for your specific transmission — is one of the most important things you can do to extend transmission life. Using the wrong fluid (especially on CVTs) causes immediate damage. At ACE, we always use the correct fluid spec for your vehicle.

Transmission Diagnostics

Not sure what’s wrong? We’ll scan your vehicle, perform a road test, and give you a complete picture of what your transmission is doing — and why. No upselling, no guesswork. We tell you exactly what we found, what it means, and what it will cost to fix.

Automatic Transmission Service

Automatic transmissions are complex systems with hundreds of internal components. Whether you drive a standard torque-converter automatic, a dual-clutch automatic, or a CVT, ACE’s specialists have the tools and experience to service it correctly. We work on all makes and models — domestic and import.

Manual Transmission Repair

Manual transmissions are less common today but still found on trucks, performance vehicles, and older cars throughout the region. Clutch wear, synchronizer problems, and bearing failures are the most common issues we see. ACE repairs and rebuilds manual transmissions with the same precision we bring to automatic work.

Transmission Repair vs. Rebuild vs. Replacement — Which Do You Need?

This is the most common question we get, and the honest answer is: it depends on the diagnosis. Here’s how we think about it:

• Repair — Best when the problem is isolated. A single failed component (solenoid, sensor, valve body) can often be fixed without disassembling the whole unit. Fastest and least expensive option when it applies.
• Rebuild — Best when internal wear is widespread. We disassemble the transmission, replace all worn components, and reassemble it to spec. Less expensive than a replacement and often more reliable than a used unit.
• Remanufacture — Best for high-mileage vehicles or transmissions with known design flaws. Built to factory spec with upgraded components where applicable.
• Replacement — Sometimes the right call, particularly on vehicles with structural damage or when a quality remanufactured unit is available at lower cost than rebuilding. We’ll tell you when this makes more sense.

We won’t recommend a rebuild when a repair will do. And we won’t push a replacement when a rebuild makes more financial sense. You’ll get an honest assessment before any decision is made.

What Makes ACE Different From a General Mechanic

General auto shops handle dozens of different repair types every day. Transmissions are one item on a long list. At ACE, transmissions are the only thing on the list.

That specialization matters because:

• Modern transmissions are complex. There are 250+ transmission families currently in the market. A general mechanic may see a given transmission type once or twice a year. Our technicians work on them daily.
• Diagnosis requires specialized tools. Generic OBD scanners read codes — they don’t tell you why a code is being thrown. ACE uses dedicated transmission diagnostic equipment that goes deeper.
• Mistakes are expensive. A misdiagnosis on a transmission can mean a minor repair turning into a full rebuild. Getting the diagnosis right the first time saves you money.
• General mechanics have 60–70% higher failure rates on transmission work within the first year compared to specialists. That’s not a knock on general mechanics — it’s a reflection of how specialized this work is.

Our 3-Year Unlimited Mileage Warranty

Every transmission repair and rebuild at ACE is backed by a 3-year unlimited mileage nationwide warranty — covering all parts and labor. That’s 3x the industry standard of 12 months/12,000 miles.

What that means for you:

• If something goes wrong with the repair within 3 years, we make it right — no mileage limit
• Coverage travels with you — valid at participating shops nationwide
• Transferable to the next owner if you sell the vehicle
• Covers both parts and labor — not just one or the other

We offer this warranty because we’re confident in the quality of our work. A shop that’s uncertain about its repairs doesn’t offer 3-year coverage.

Frequently Asked Questions

How long does a transmission repair take? Most transmission repairs and rebuilds at ACE are completed in 1–3 business days. Complex remanufacturing jobs may take longer — we’ll give you a specific timeline with your estimate.

How do I know if my transmission needs service? Common warning signs include slipping gears, shuddering or shaking during acceleration, delayed engagement when shifting from park to drive, a burning smell, or a check engine light related to transmission codes. If you’re experiencing any of these, bring it in for a diagnostic before the problem gets worse.

Should I repair or replace my vehicle? We get this question often. The honest answer is that a properly rebuilt transmission by a specialist typically lasts 150,000+ miles. If your vehicle is otherwise in good shape, a rebuild or remanufacture almost always makes more financial sense than a car payment. We can help you work through the numbers.

Will my warranty transfer if I sell my car? Yes. ACE’s 3-year unlimited mileage warranty is transferable to the next owner — which can actually add value to your vehicle at resale.

Do you work on all makes and models? Yes. We service all domestic and import vehicles including cars, trucks, SUVs, and commercial vehicles.
