There are several factors to consider when comparing used and remanufactured transmissions. In this article we explain some of the key differences to help you make informed decisions when replacing a transmission or any other heavy duty truck parts for that matter.

Pros and Cons. The main benefit of buying a used transmission is the initial cost savings since used is less expensive than remanufactured. Sometimes a used transmission is more readily available for a fast repair to get back on the road. Also, if your core is not like-for-like, it may be more cost effective. A remanufactured part will last longer, thus providing longer term costs savings. Therefore, it is wise to consider how long you plan to use the part when making your decision because the main con to a used part is a shorter running life then a REMAN.

A properly remanufactured transmission is as close to new as you can possibly get. With all the moving parts in a transmission, it is important to make sure what you are purchasing is built with quality workmanship. There are a few terms used in the industry that describe how extensively a transmission has been gone through. Reconditioned, Rebuilt, and Remanufactured are “terms” that are sometimes loosely stated to customers and you may not be getting the quality transmission you are expecting. A Reconditioned transmission has typically been inspected and only the parts that need to be replaced are replaced. Rebuilt typically means that a unit has been disassembled, cleaned, and reassembled with all used parts and possibly new bearings and seals. Remanufactured is an extremely thorough process. A core transmission will have been completely disassembled, cleaned and magnaflux inspected for cracks. The parts that are reused meet or exceed OEM specifications. Gearing that is reused, most of the time will be remated with its original running mate. Once all components are inspected and ready for reassembly, OEM procedures are followed, and the units are assembled with quality checks in place and are properly lubed and sealed. These units typically carry a one- or two-year warranty on manufacturer defective workmanship and defective parts. 

In summary, buying a used transmission is a good option if the initial cost is an important issue. If going for longevity and you have the financial means to do so, a remanufactured transmission is the way to go.

Either option you choose, it is vitally important to make sure you clean out any used lines and your transmission cooler. These can hold contaminated fluid and metal chunks which in turn can reduce the life of or damage your replacement transmission.
