Is It Better to Buy a Used Transmission or Rebuild a Transmission?

Your transmission is one of your car’s most important parts, as it ensures your wheels are getting the right amount of speed and power from the engine. 

But transmissions can wear down and stop working. If you notice that your car is slipping out of one gear into another, or you have started to notice a burning smell when driving your car, that may be a sign of transmission problems

If this is happening to you, it may be time to find a new transmission. Below we’ll go over the differences between used transmissions vs rebuilt transmissions in your vehicle. 


One of the main reasons for purchasing a used transmission instead of going through the rebuild process is because of the price. It’s true that buying a used transmission is generally cheaper compared to getting your transmission repaired. 

However, you get what you pay for. Often used transmissions are cheaper because they are less reliable. It’s hard to know the history of the transmission precisely, and you don’t want to get stuck with a transmission that wasn’t taken care of by the previous driver or has already been subject to shoddy repair work. 

Though the used transmission may be cheaper in the short term, if you have to repair it constantly because it isn’t in good condition, the long-term cost could end up being just as expensive or even more than a rebuild. 

Perfect Fit

When you rebuild your old transmission instead of replacing it with a used one, you are continuing to use a transmission explicitly designed to work with your car. It is perfectly tuned in to sync with your engine and your system in a way that a different transmission might not be. 

If you are rebuilding a transmission, you can still reap the benefits of having the right transmission for your car while taking care of your vehicle’s condition and performance.

Longevity and Resale Value

After driving on a transmission for too long, the wear and tear will mean that the number of miles left for your car to drive safely and comfortably is numbered. Getting a rebuild is a great way to counteract this and extend the life of your car. 

Because of this, a car with a rebuilt transmission will also have a higher resale value. Buyers are wary of a car whose transmission has hundreds of thousands of miles on it, but a rebuilt transmission means that your vehicle is in better shape and can earn you more money on the market down the road.
