Continuously Variable Transaxle (CVT) Operation
Weber State University (WSU) - Automotive Technology Department - Transmission Lab. GM Continuously Variable Transaxle (CVT) model VT25. How a belt-driven CVT Works. Ford, GM, Honda, Chrysler (JATCO), and Nissan CVTs are similar. CVTs allow the engine to operate at the RPM for peak efficiency while increasing and decreasing the transmission drive ratio to change vehicle speed. This video helps satisfy NATEF Task A2.C.23. "Describe the operational characteristics of a continuously variable transmission (CVT)", a priority 3 task. eCVTs are different and are demonstrated in another WeberAuto video.

CVT Transmission Pressure Tests
CVT Transmission Pressure Tests Get the book here: The procedures presented here are specific to the Jatco Nissan Sentra CVT transmission. However, these procedures can be effected on any CVT, with the difference being the pressure ports change. Any service manual, will show you the proper ports for the CVT you're working on. Your first tool of choice, is a high pressure gauge, or high pressure electronic transducer. You can also use an oscilloscope, or even better, a graphing multi meter to record the pressure waveforms. Finally, we'll also present a little known device, but with great usefulness. It is called, a duty cycle controller circuit. These duty cycle circuits are now sold at many electronic houses, and can be used to control any electrical solenoid. Most, but not all of them, have variable voltage settings. In our case, we'll use 12 volts. Assuming you'll be using a pressure gauge, use the diagrams seen here, to connect the gauge. Start the engine, and raise the vehicle up in the air, using a shop lift. If not using a lift, do not go under the car with the engine on. Remember that each time we change to a different pressure port, we have to turn the engine off, since the ports are ...
