APX uses only top quality remanufacturers to supply our clients with professionally remanufactured Transmissions. Prior to being shipped All of our Remanufactured transmissions are tested with industry leading diagnostic equipment to ensure your replacement transmission will perform similar or better than a brand new Transmission.

Every unit is put through a set of grueling tests before it ever gets approved for installation and stamped with the nationwide warranty. The “dynos” do a comprehensive evaluation of each unit. We have the highest percentage of first-time-working transmissions in the industry.
Every transmission is remanufactured by a single ASE-Certified builder. From disassembly and inspection to complete reassembly. Ensuring 100% quality control. Each builder is an expert on a specific family of transmissions. This specialization allows our suppliers to build units faster and with fewer failures.
Remanufactured vs. Rebuilt
APX carries Certified Factory Remanufactured Transmissions.
We don’t sell Rebuilt Transmissions and here’s why you don’t want one
  • Rebuilding means only fixing the broken parts. Remanufacturing means:
  • Completely disassembling and inspecting the unit
  • Replacing all soft parts (clutches, seals, etc.) with new ones
  • Checking all hard parts, and re-machine the worn ones
  • Bring unit back to like-new quality, including any OEM updates
  • Stress-testing the finished unit
Not even close, Here’s why….
Remanufactured Transmissions are known in the industry to be a much more superior product. It will perform better than a rebuilt or used Part.
Rebuilt parts are exactly what they sound like, the Transmission is disassembled, and then an investigation process determines which part failed. At that point that failed part is replaced, (Often with a used part) and then the Transmission is put back together, and installed in the vehicle. This leaves you with a rebuilt Transmission that could potentially have the same or a different problem. This is because only one part is replaced, and the worn transmission is put back on the road with all the old parts inside of it.
Remanufacturing is the process of restoring the Transmission to its original condition. New parts are installed as needed, everything is measured and tested for dimensional tolerances, and is stamped with a parts and labor warranty. Once the professional remanufacturing process is done, the Transmission resembles a new Transmission with 0 miles on it. These transmissions are backed with a 3 Year Parts and Labor Nationwide warranty
