Details & Inspection Notes

Part Number / SKU: 10375T

Every remanufactured transmission we sell is backed by a Million Mile warranty up to 7 years, the best in the industry. The reason we can offer this warranty? Every transmission undergoes the same rigorous remanufacturing process:

  1. Teardown and Triple CleanEvery transmission is disassembled, inspected, and cleaned three times. We also chase all threads and install all new bushings during this process.
  2. Valve Body Rebuild and TestOur most experienced team members rebuild and inspect each valve body before testing it using our C.A.R.S. testing system, which simulates real-world use and validates the valve body.
  3. New O-Rings, Gaskets, and SealsOnce the valve body is tested, the transmission is reassembled with all new o-rings, gaskets, and seals.
  4. Dyno TestingOur custom dyno testing machines spin and load test every transmission to verify it’s ready for the road.

When you buy a remanufactured transmission from Aero Engines Inc, you’re buying a transmission that meets or exceeds OEM specifications. And we back that claim up with our available 7 Year, 1 Million Mile Warranty.
