THE DRIVETRAIN DIAGNOSTIC TOOL

TestBox can directly diagnose transmission problems for on- and off-highway vehicles – and verify whether a transmission is performing properly – by measuring sensors and solenoids, displaying the results on an easy-to-read screen.

TestBox

If an issue is due to bad sensors, connectors, harnesses or solenoids, TestBox allows the operator to override the OEM controls to the transmission and move stalled heavy equipment off the road or to a nearby garage, saving time and money.

Testimonials

“We were very impressed by the TestBox and the 'get home' capability it offered that saved us a costly tow bill. I believe TestBox is a beneficial tool that has great potential to continue saving our city money.”

“With the TestBox, our non-operating truck was actually driven to a nearby crane shop, where they could fix it. TestBox was so helpful that we bought one in case it happens again.”
