What Is a Transmission Rebuild?

Repair, rebuild, or replacement are usually your three options if you're experiencing issues with your car's transmission. Once a professional technician evaluates your vehicle and concludes that a fix is not enough, they typically recommend a transmission rebuild.

Examples of When a Repair May Not Work

  • When the extent of the damage is excessive: If more than a couple of parts are impacted and need to be removed and replaced, it may be better off for you to replace a portion of the entire transmission.
  • You are servicing your transmission more often: If you've had your transmission repaired multiple times in a short amount of time, it's a clue that you may need more than a simple fix. In some cases, the cost of those repairs may have already cost you more money than if you were to rebuild or replace the transmission.
  • You're hearing grinding noises: If you hear scary noises when shifting gears, it usually points to a problem with your transmission's gear synchronizers. When this happens, a new or rebuilt transmission is often needed.
  • The transmission is completely dead: When your transmission has entirely stopped working, a replacement or rebuild is the only option.

Why A Transmission Rebuilt Is More Cost-Efficient Than a Replacement

After you've figured that a simple repair isn't the most suitable choice for your vehicle, you must then decide whether to get a replacement or rebuild. You might think the newness of a replacement is always better, right? A replacement is not always the best option in every circumstance. 

Rebuilding your transmission includes disassembling the region, replacing old, damaged, or broken parts with new ones, and retaining the components that are still in good condition. Replacement transmissions are essentially rebuilt transmissions, remanufactured in a factory setting instead of a shop setting. A rebuild is a more cost-efficient route, and it enables the mechanic to swap out certain more up-to-date parts.
