Description

Fraser Engines Remanufactured Transmission Quality Standards

Every Fraser Engines remanufactured transmission is built, tested, and validated to deliver dependable performance, long service life, and smooth operation under real-world driving conditions.

What’s Included & How We Ensure Quality

✔️ A remanufactured and improved torque converter is included with every transmission at no additional cost.

✔️ To prevent front seal leaks, vibration, and premature bushing wear, all torque converters are thoroughly tested for leak integrity, lock-up operation, concentricity, and balance.

✔️ Every fully remanufactured valve body receives complete system correction and recalibration, then is tested independently prior to installation.

✔️ All wear-prone valves are restored to stringent specifications and vacuum tested to verify proper sealing and operation.

✔️ Each remanufactured transmission undergoes hot, cold, load, and simulated road testing using our proprietary CARS® (Computer-Aided Road Simulation) dynamometer program, replicating real driving conditions before release.

Warranty You Can Trust

✔️ All Fraser Engines remanufactured transmissions are backed by an industry-leading, no-hassle nationwide warranty, providing real protection and peace of mind long after installation.
