When your vehicle’s transmission shows signs of trouble, it’s a serious concern. As a vital part of your car’s drivetrain, the transmission transfers power from the engine to the wheels for optimal performance and control. At ATech Transmission, we understand that a well-functioning transmission is essential for both vehicle performance and driver safety. However, transmissions endure wear and tear over time. In many cases, a rebuild is often the best option for reviving your vehicle’s performance and extending its lifespan. Below, we’ll explore the reasons a rebuild might be necessary and walk you through our meticulous rebuilding process.
The ATech Transmission Rebuilding Process.
Rebuilding a transmission requires expert attention to detail. That’s why we follow a tried-and-true, multi-step process to ensure each rebuild meets our own exceptionally high standards.
initial Diagnosis.
Our process begins with a thorough diagnosis. Our technicians will discuss your vehicle’s symptoms with you, gathering information on issues like unusual noises or shifting delays. We look for details such as unusual noises, slipping gears, or delayed shifts, which help narrow down potential causes. We use advanced diagnostic tools to pull codes from the vehicle’s computer system, which may indicate specific issues within the transmission. This comprehensive approach allows us to pinpoint underlying problems. It also gives us the ability to approach the rebuild with a full understanding of the transmission’s condition.
Inspection.
Next, we conduct an in-depth inspection. We lift the vehicle to examine the transmission for signs of wear, leaks, or damage. We assess the condition of the transmission fluid, checking for contamination, discoloration, or a burnt odor, which are indicators of internal issues. This inspection helps us identify which components need replacement or refurbishment, and it also provides us with valuable insight into the overall health of the transmission.
Disassembly.
We remove the transmission from the vehicle and disassemble it piece by piece. Each component is carefully labeled and organized to allow for accurate and efficient reassembly. This step allows us to access and assess each part individually, identifying specific areas that require attention along the way.
Replacement of Parts.
After identifying worn components during disassembly, we replace them with high-quality, durable parts. Common replacements include clutches, gears, bands, seals, gaskets, filters, and solenoids. Clutches and bands are particularly prone to wear and tear, so we’ll make sure they are replaced to restore optimal performance. We also replace any seals or gaskets that may be leaking to prevent fluid loss and contamination in the future. Each new part is selected based on quality and compatibility with the transmission model because our goal is a rebuild that will last for years to come.
Reassembly.
With new components ready, we begin reassembly by carefully aligning and securely fitting every piece. This step requires utmost precision, because even a slight misalignment can lead to performance issues. We follow manufacturer specifications closely to restore the transmission's functionality and performance.
Testing.
Our final step is rigorous testing to confirm that the rebuilt transmission performs flawlessly. We start with bench testing, where we run the transmission on a test stand to monitor its shifting and fluid flow. Once the bench test is successful, we take the vehicle for a test drive to evaluate performance under real-world conditions. During this drive, we’ll check for smooth shifting, proper power transfer, and any unusual noises or vibrations. We’ll only consider the rebuild complete when the vehicle has passed both of these important testing phases with flying colors

Reasons for a Transmission Rebuild.
The need for a transmission rebuild often arises from worn or damaged components. Over time, essential parts like gears, clutches, and bands can deteriorate due to constant use. This wear may result in delayed shifting, a rough feeling during shifting, or even a complete failure to shift between gears. Each component has a specific role. When these components wear out, it can lead to erratic shifting, slipping out of gear, and a frustrating, potentially dangerous driving experience.
