ATRA Certification Prep Guide

ATRA Certification Prep Guide PDF. This guide was developed to help you recognize any weaknesses in your technical understanding of automatic transmissions, so that you could focus your studies to help you pass the ATRA Certification program.

But even more than that, its ultimate goal is to help you improve your overall understanding of automatic transmissions, to help you do a better job where it counts: in the shop.

A look at the contents page might lead you to believe that this is a complete transmission training program. It isn’t. The information here is generally brief, and was created strictly to offer an overview on the subject matter. The idea was to help you recognize the issues considered important for diagnosing and repairing today’s transmissions. If you’re comfortable with your understanding of those issues, you should have no problem with the ATRA Certification Test, or with the day-to-day requirements of your work in the shop.

On the other hand, if you find yourself unfamiliar with some of the information here, you owe it to yourself to dig deeper, to learn more about that subject, until it’s a part of your basic understanding of transmission technology.
