It's a computer analyzer and breakout monitor hooked to your vehicle at the computer connector. It monitors signals from the computer to the transmission to see if the vehicle's computer is sending proper commands to the transmission.
This monitor is also capable of bypassing the computer and operating the transmission, thereby telling the technician if the transmission is working or not, and if the computer is sending the proper signals.
This scanner allows us to tap into the vehicle computer's memory to see if any trouble codes are present. These codes indicate that a malfunction is taking (or has taken) place, either now or sometime in the past. These codes narrow down the trouble area to make diagnosis easier.
In addition, the scanner is equipped with a 'troubleshooter' that indicates what to look for when certain codes or symptoms are present. It also allows the vehicle to be driven while monitoring the data that each sensor is sending to the computer.
These solvent flushers use air pressure and pulsating action to break out small contaminants that collect in the transmission cooler - a 'must do' on every job!
This is used to flush the transmission cooler with hot transmission fluid on extremely contaminated jobs. The radiator expands with heat, thereby dislodging any contaminants still in the cooler after the solvent/air pressure flush.
This flusher is used on jobs with light contamination to flush the converter. It uses pulsating air and solvent to dislodge particles in the converter's turbines. In most cases, the converter gets replaced.
