A lot of people purchase a used car because they can save money and know that it will be just as good as new. You can expect the same benefits if you buy a used transmission for car. It is more affordable to buy used transmissions than new ones. This is a significant factor. You can often save hundreds of dollars in many cases. Many transmissions that are used are technically remanufactured. This means they have new parts and updated. A transmission could be almost identical to a brand new one.
