Borg Warner started manufacturing the T5 transmission in 1982. Since its inception, the transmission has been placed into various vehicles, including Ford and General Motors models. The five-speed transmissions fall into two categories: world class and non-world class. The T5 is credited as the only American-made manual transmission to be in production for more than 20 years. The Borg Warner T-10 also is a popular transmission, and both have identifying marks.
Finding the Identifiers
Locate the identification tag number. A quick way to confirm that your transmission is a Borg Warner and what vehicle it was designed for, is to locate the identification number stamped into the “metal tag bolted onto the tail housing,” according to 5speeds.com.
