We maintain Southern California's largest inventory of exchange transmissions for Caterpillar applications. American Independent is located near the Port of Los Angeles, giving us the ability to service the global market.

Several things set American Independent apart. First is our attention to quality. Quality is built into every transmission that leaves our shop--from the over 100 years experience of our mechanics to our high standards relating to reusability. In addition, our custom built Transmission Dynos allow us to test and adjust before the unit is installed in your machine.

The American Independent Quoting System allows our customers to understand the transmission failure and make informed decisions regarding the replacement of critical components resulting in a rebuild that is right for their application and budget.

Many suppliers have Warranty policies that consist of pages of legal mumbo jumbo. We'll send you ours if you want. But what it comes down to is the integrity of the people in the business and their willingness to do what is right. Period. Simple.

The next time one of your CAT® machines needs work on a TRANSMISSION, TORQUE CONVERTER, DIFFERENTIAL, or FINAL DRIVE, please try American Independent. Give us a chance to earn your business.
