The SuperFlow SuperShifter tester/shifter combines years of transmission testing experience and state-of-the-art electronics into an easy-to-operate, handheld diagnostic tool. Designed for in-vehicle use, the SuperShifter automatically displays pressure and PRNDL switch status, temperature and speed sensor information. It displays solenoid names and impedances to help operators determine whether or not test results are within spec, and eliminates the need for an ohmmeter or pages of reference tables and data sheets.
