The SuperShifter® in-vehicle tester allows you to shift automatic transmissions in the same manner as the vehicle's computer. This durable unit is designed to handle day-in, day-out professional usage. All components are housed in robust, impact-resistant, environmentally protected enclosures. The SuperShifter® is a complete in-vehicle testing solution that can test 12 solenoids simultaneously. Source or sink each solenoid channel for up to three amps and configure for "highside" or "low-side" drive. Cable and test specifications kits are available for most modern transmissions to make it easy to set up tests. Many of the testing options are user-selectable so you can choose to run simple or comprehensive tests.
