The most expensive parts for most vehicles are the large drivetrain components like the engine, transmission, and differentials. If you are on a limited budget, you may want to consider a used transmission as an alternative to a new one if your car or truck needs a replacement, but there are some things you should look for before buying one.

Grease, Oil, And Dirt

Buying a used transmission for your vehicle is a good alternative if you can't find a new one or are working with a limited budget. When looking at used transmissions for sale, you may find some used transmissions that are extremely dirty or covered in oil and grease. Transmission in this conditioning may indicate that it has been leaking and is lacking service. 

A large amount of oil, grease, and dirt on the outside also makes it challenging to inspect the case of the transmission for damage like cracks or broken pieces. A reputable shop or salvage operator will power wash used transmissions they are selling before they put them out for customers to view. If you do not know the history of the transmission, and it is extremely dirty, you may want to skip it unless it is the only one you can find. 

Replacement Warranty

A used transmission for sale through a private party is always a gamble because they often are not going to offer a replacement warranty if the transmission does not function properly. However, if you purchase the transmission from a salvage yard or an automotive shop that sells used parts, ask about the warranty that comes with the unit. 

At a minimum, the shop or salvage yard should offer you a replacement guarantee in case the transmission doesn't work once installed in the vehicle. The warranty is often limited, and the seller may not know much about the vehicle it came from. However, they should be willing to replace the transmission if you get it installed only to find out there is a problem with it.

Rebuilt Transmissions

You can often find used transmissions that have been remanufactured or rebuilt prior to the sale. These units often come from transmission shops and will reuse the case and some of the internal parts from the original assembly. However, new bearings, seals, and other parts will ensure the transmission functions correctly in your vehicle.  

The cost of a rebuilt transmission is often higher because the shop needs to cover the cost of the parts and labor they have put into the unit. However, a rebuilt transmission is significantly more affordable than a new one, and if you have an older car with a rare transmission, a used transmission or a fresh rebuild may be the only option available.
