Basic Knowledge Required

NOTICE: Lack of basic knowledge of this transmission when performing the diagnostic procedures could result in incorrect diagnostic results or damage to the transmission components. Do not, under any circumstances, attempt to diagnose a transmission problem without this basic knowledge.

You must be familiar with some of the basics of transmission operation and electrical diagnosis in order to use this section.
- Basic Electrical Circuits: You should understand basic electricity and know the meaning of voltage (volts), current (amps), and resistance (ohms). You should understand what happens in a circuit with an open or a shorted wire and you should be able to identify a shorted or open circuit by using a DVM. You should be able to read and understand a wiring diagram.
- Use Of Digital Voltmeter: You should be familiar with the Digital Voltmeter (DVM), particularly essential tool J 39200. You should be able to use the meter in order to measure voltage (volts), resistance (ohms), current (amps), capacitance (farads), intermittents (min/max) and frequency (Hertz).
- Use Of Special Tools: You should not use a test light in order to diagnose the transmission controls system unless specifically instructed to do so. You should know how to the use jumper wires in order to test the components and to allow the DVM readings without causing damage to the terminals. You should know how to use the Connector Test Adapter Kit, J 35616 whenever the diagnostic procedures call for front probing of any connector. You should be able to use a line pressure gauge set.
