​

What Is a Transmission Core Charge and How Does the Core Return Process Work?

​

All Eagle Engine remanufactured transmissions are sold with a refundable core deposit and skid charge. The core deposit helps ensure the return of your old transmission, which is used in the remanufacturing process.

​​

Once your remanufactured transmission has been installed, simply contact our team at (800) 811-9328 to schedule your core return. When an acceptable core is received and inspected, your core deposit will be refunded.

​

To qualify for full core credit, the returned transmission must be a like-for-like make, model, and type as the unit purchased. The core must be returned assembled, drained of all fluids and oil, and securely attached to the same undamaged skid or shipping container used for delivery.

​

Core returns must be received within 60 days of the delivery date to qualify for credit. Most cores receive full credit; however, deductions may apply for certain damages or conditions as outlined in our core policy.​

​

If you have questions about core eligibility or the return process, our team is happy to help before you place your order.

​

What's the Difference Between a New, Used, Rebuilt, and Remanufactured Transmission?

​​

When replacing a failed transmission, you'll typically have four options: new, used, rebuilt, or remanufactured. Understanding the differences can help you make the best decision for your vehicle and budget.

​

New Transmissions are brand-new units supplied by the original manufacturer. While they offer excellent performance, they are often the most expensive option and may not be available for older vehicles.

​

Used Transmissions are removed from donor vehicles and sold with little or no internal inspection. While they are usually the least expensive option upfront, their maintenance history, mileage, and internal condition are often unknown, making them the highest-risk choice.

​

​Rebuilt Transmissions are typically repaired only in the areas where a failure occurred. Depending on the rebuilder, many original components may be reused if they appear serviceable. Quality and reliability can vary significantly from one rebuild to another.

​

Remanufactured Transmissions offer the best balance of reliability, performance, and value. A remanufactured transmission is completely disassembled, thoroughly cleaned, inspected, precision machined, and reassembled to meet or exceed original equipment specifications. Wear components are replaced, common failure points are addressed, and upgrades may be incorporated to improve durability and performance.

​

For most vehicle owners, a remanufactured transmission is the preferred replacement option because it delivers near-new reliability at a significantly lower cost than a new transmission. It also provides greater peace of mind than a used transmission and a more comprehensive restoration than a typical rebuild.

​

At Eagle Engine Sales, our remanufactured transmissions are engineered for long-term dependability, tested for performance, and backed by warranty coverage to help keep you on the road with confidence.

​

Do Remanufactured Transmissions Come With a Warranty?

​

Yes. One of the biggest advantages of purchasing a remanufactured transmission is the warranty protection that comes with it.

​

At Eagle Engine Sales, every remanufactured transmission includes a 3-Year / 100,000-Mile Warranty with nationwide parts and labor coverage, giving you confidence whether you're driving across town or across the country. Unlike many used transmissions that offer limited coverage—or no warranty at all—our remanufactured units are backed by comprehensive protection designed to keep you on the road.

​

We also provide labor reimbursement up to $95 per hour (standard) for eligible warranty repairs, helping reduce out-of-pocket costs should a warranty issue arise. This added protection is one of the reasons many vehicle owners, repair shops, and fleets choose a remanufactured transmission over a used or salvage-yard replacement.

​

For even greater peace of mind, customers can add our Optional No-Fault Warranty for only $100. This enhanced coverage provides additional protection beyond our standard warranty and is one of the most affordable ways to safeguard your investment.

​

Because our remanufactured transmissions are completely disassembled, thoroughly inspected, precision machined, and rebuilt to meet or exceed original equipment specifications, we're able to stand behind them with industry-leading warranty coverage.

​​

How Long Does a Remanufactured Transmission Last?

​

A high-quality remanufactured transmission can last 100,000 miles or more when properly installed and maintained. In many cases, a remanufactured transmission can provide service life comparable to a new transmission while costing significantly less.

​

The lifespan of a remanufactured transmission depends on several factors, including the quality of the remanufacturing process, installation procedures, vehicle maintenance, driving habits, and operating conditions. Transmissions that are properly installed, serviced with the correct fluid, and maintained according to manufacturer recommendations often deliver many years of dependable performance.

​

One of the key advantages of a remanufactured transmission is that common wear items and known failure points are addressed during the rebuilding process. Unlike a used transmission, which may already have thousands of miles of wear and unknown internal conditions, a remanufactured transmission is completely disassembled, inspected, machined, and rebuilt to meet or exceed original equipment specifications.

​

At Eagle Engine Sales, our remanufactured transmissions are built using quality components and are designed to provide long-term reliability for daily drivers, work trucks, fleet vehicles, and commercial applications. That's why every transmission includes our 3-Year / 100,000-Mile Warranty with nationwide parts and labor coverage, giving you added confidence in your investment.

​

To maximize the life of your remanufactured transmission, we recommend following all installation requirements, flushing or replacing the transmission cooler when necessary, using the correct transmission fluid, and addressing any drivability concerns promptly.

​

Are Remanufactured Transmissions Reliable?

​

Yes. A professionally remanufactured transmission is one of the most reliable replacement options available and can often provide performance and durability comparable to a new transmission.

​

Unlike a used transmission, which is removed from another vehicle with an unknown history, a remanufactured transmission is completely disassembled, thoroughly cleaned, inspected, machined, and rebuilt using new or upgraded components where needed. Worn parts are replaced, critical tolerances are restored, and many common failure points are corrected during the remanufacturing process.

​

In many cases, a remanufactured transmission can actually be more reliable than the original factory unit because known design weaknesses may be addressed with updated components and improvements developed over years of field experience.

​

The key to reliability is choosing a high-quality remanufactured transmission from a reputable supplier. Not all rebuilt or remanufactured transmissions are created equal. The quality of the components used, the remanufacturing process, testing procedures, and warranty support all play a major role in long-term performance.

​

At Eagle Engine Sales, our remanufactured transmissions are built to meet or exceed original equipment specifications and are designed to deliver dependable shifting, long service life, and reliable performance. Every unit is backed by our 3-Year / 100,000-Mile Warranty, including nationwide parts and labor coverage and labor reimbursement up to $95 per hour (standard). For additional peace of mind, customers can also add our Optional No-Fault Warranty for only $100.

​

If you're looking for a replacement transmission that offers a balance of reliability, performance, warranty protection, and value, a remanufactured transmission is often the smartest choice.

​

​How Do I Know Which Transmission Fits My Vehicle?

​

Finding the correct transmission for your vehicle is important, as many vehicles were offered with multiple transmission options depending on the year, engine size, drivetrain, and production date.

​

The easiest way to ensure you receive the correct transmission is to provide your vehicle's VIN (Vehicle Identification Number) when requesting a quote or placing an order. Our transmission specialists can use the VIN to verify the exact transmission originally installed in your vehicle and identify any application-specific requirements.

​

In addition to the VIN, it is helpful to have the following information available:

​

✔ Year, Make, and Model
✔ Engine Size
✔ 2WD, AWD, 4WD, or RWD Configuration
✔ Transmission Code (if available)
✔ Any Existing Transmission Part Numbers or Tags

​

Many transmissions may look similar externally but contain different gear ratios, electronics, bellhousing patterns, sensors, valve bodies, or programming requirements. Ordering the correct transmission from the start helps avoid installation delays, additional costs, and fitment issues.

​

At Eagle Engine Sales, our experienced team verifies application information before your order ships to help ensure you receive the correct remanufactured transmission for your vehicle. If you're unsure which transmission you need, we're happy to assist with the identification process.

​

Not sure which transmission fits your vehicle? Call (800) 811-9328 and have your VIN ready. Our transmission specialists will help identify the correct transmission and provide pricing and availability.

​

Are Your Remanufactured Transmissions Tested Before Shipping?

​

Yes. Every Eagle Engine Sales remanufactured transmission undergoes a thorough inspection and quality control process before it is approved for shipment.

​

During the remanufacturing process, each transmission is completely disassembled, cleaned, inspected, and rebuilt using quality replacement components. Critical internal parts are measured and evaluated to ensure they meet strict specifications, while worn or damaged components are replaced as needed.

​

Before shipping, transmissions are subjected to comprehensive quality assurance procedures to verify proper assembly, component operation, and overall performance. This helps ensure that each transmission meets or exceeds original equipment specifications and is ready for installation upon arrival.

​

Our goal is to provide customers with a transmission that delivers dependable shifting, long service life, and reliable performance from day one. By combining quality components, precision remanufacturing, and rigorous testing procedures, we help reduce the likelihood of premature failures and installation-related issues.

​

Because we stand behind the quality of our products, every remanufactured transmission is backed by our 3-Year / 100,000-Mile Warranty, including nationwide parts and labor coverage and labor reimbursement up to $95 per hour (standard). Customers can also add our Optional No-Fault Warranty for only $100 for even greater peace of mind.

​

When you purchase a remanufactured transmission from Eagle Engine Sales, you can feel confident knowing that your unit has been carefully inspected, tested, and prepared for reliable operation.
