Two Transmission Dynos.
Be Assured.

We installed a brand-new PowerTest dynamometer for our Caterpillar transmission line in our Gardner, IL shop earlier this year — one of the most capable CAT transmission dynos in the rebuild industry. Our second dyno handles the Volvo PT Series.

Every transmission we ship is run on a dyno under full load — no exceptions. If it doesn’t pass, it doesn’t ship.
