Where Reliability Begins — One Transmission at a Time
Reliability doesn’t happen by accident. It’s built, tested, and proven — one part, one process, and one transmission at a time.
At Gearhead Engines, our reputation for long-lasting performance starts in the remanufacturing process itself. Every remanufactured transmission that leaves our facility goes through a series of carefully controlled, precision-driven steps to ensure it performs as good as — or better than — new.
Here’s how we do it:
- Identification
Before any work begins, our team identifies the exact transmission and every part required for the rebuild.
At Gearhead, “close enough” doesn’t exist. Using advanced cataloging systems and decades of experience, we make sure every unit is matched to its precise application — so you receive the right product, every time.
- Teardown, Cleaning, and Inspection
Each transmission is completely disassembled. Our technicians carefully inspect every component, removing worn, damaged, or defective parts so any part that does not meet our specifications re-enters the assembly process. This step ensures the foundation for a transmission that performs like new.
- Precision Machining
When parts need attention, they go to our skilled machinists, who restore every component to factory specifications.
This stage isn’t just repairing — it’s remanufacturing. Every surface, seal, and tolerance is corrected to match OEM standards, including the latest factory upgrades.
- Cleaning
Once the machining process is complete, every part goes through a final high-pressure steam wash to remove any contaminants.
Clean components mean consistent performance and long-term dependability.
- Valve Body & Electrical Testing
Modern transmissions depend on both mechanical precision and electronic communication.
Our technicians remanufacture each valve body, ensuring every valve and fluid channel operates smoothly. Then we test sensors, solenoids, and solenoid packs to ensure the transmission will shift accurately and communicate properly with your vehicle’s onboard computer.
- Assembly
Within our state-of-the-art 200,000 sq. ft. remanufacturing facility, every transmission is assembled by experienced technicians following strict quality protocols. We don’t rush — we repeat. Every unit is built the same way, every time, to deliver consistent results.
- Dynamometer Testing
Once assembled, each transmission is tested on our fully automated dynamometer, simulating real-world driving conditions.
Over 300 data points are measured during this test — ensuring your transmission performs flawlessly under load, temperature, and speed before it ever leaves the factory.
- Final Inspection & Shipping
Every Gearhead transmission undergoes a final quality inspection, complete with a dynamometer report and assembly verification.
Then it’s placed in a custom shipping container — designed to protect it during transit and make core returns easy and safe.
When it arrives, you can install it with complete confidence, knowing it’s already been tested, inspected, and proven reliable.
Why It Matters
The Gearhead process isn’t just about rebuilding parts — it’s about rebuilding trust. Every step, from identification to final testing, is designed to make sure your transmission performs right for the first time — and keeps performing for years to come.
