Welcome to the PTT Website

The Premium Tech Tool website covers important technical information for Mack Trucks, Prevost, UD and Volvo Trucks in North America.

Important News

The 2.5.65 update “What’s New” help file is not accurate for the North America vehicles.  Please disregard.   The correct information can be found in the March FAQ document.

Premium Tech Tool 2.03 is no longer supported and can only be used in offline mode.  Please update your Premium Tech Tool computers to avoid interruption.

Client update 2.04.87 is required when using Premium Tech Tool version 2.04. This required update is due to the expiration of the embedded licensed version of Java.  Click here for details  on “How to Update PTT using the Client Update Utility”

We strongly encourage all dealers and fleets to use the current version.

Tip of the Month:   I am having trouble connecting to the product with the Dearborn adapter.

If you are using the Dearborn 5, ensure that the “DGDPA5SA” driver is the ACTIVE one in the settings tab.  You can have both the DGDPA5MA and DGDPA5SA driver versions, but PTT works best with

the “Singe Application” version.
