With its promising results, you might be wondering how to rebuild an auto transmission and if it’s something you can do yourself.

Why You May Need to Rebuild an Auto Transmission

Before diving into the specifics involved in how to rebuild an auto transmission, it’s essential to recognize the signs of transmission problems. Ignoring these indicators can lead to more severe issues and hefty repair bills. Here are some common signs that your transmission might need attention:

  • Strange Noises: Whining, clunking, or grinding noises when your vehicle is in gear can indicate transmission issues.
  • Slipping Gears: If your transmission slips in and out of gear unexpectedly, it’s a clear sign that something is amiss.

Rebuilding an auto transmission is a complex process that requires expertise and precision. Here’s a simplified step-by-step guide on how to rebuild an auto transmission:


Before starting the rebuilding process, our skilled technicians perform a thorough diagnosis. This involves assessing the extent of the damage and identifying the specific components that need attention.


The transmission is meticulously disassembled, with each part undergoing a thorough inspection to identify any signs of wear and tear.
