TRANSMISSION REPAIR IN ARLINGTON, WASHINGTON

Ed's Transmissions proudly serves drivers in Arlington, Washington, with complete transmission testing and thorough system inspections. Our skilled auto repair technicians review every component with precision, ensuring nothing is overlooked during the diagnostic process.

Inspection & Testing

Every transmission we service in Arlington, Washington receives a full, detailed evaluation from our experienced technicians. The housing is carefully examined for cracks, distortion, worn threads, and flatness at the valve body mating surfaces to help prevent cross leaks.

Key internal components including planetaries, pumps, gears, and shafts are assessed individually for proper tolerances, spline condition, excessive clearance, stress fractures, and any signs of abnormal wear. Modern electrical parts such as solenoids, force motors, switches, and wiring are also tested using specialized diagnostic equipment. Our test boxes verify that solenoids and switches function correctly under pressure and with the proper voltage, ensuring your transmission performs exactly as it should.

For drivers in Arlington, Washington, we take every transmission through a precise and thorough teardown and inspection. All internal components are removed, evaluated for wear, scoring, or distortion, and replaced when they do not meet exact specifications. The transmission casting is inspected for any distortion and resurfaced to ensure proper flatness.


Valves and springs are measured for correct tension, and all applications are tested on our Answermatic valve body test unit prior to reassembly. This careful process helps ensure smooth, reliable operation once your transmission is back on the road.

Dynamometer Testing

After the testing process is finished, we provide a detailed report outlining all findings and work performed. This confirms that your transmission has met our strict quality control standards. Once the unit is fully assembled, it undergoes a series of rigorous performance tests, including:
