I apologize for the coughing during the video. I am not a smoker, I am not sick, I just took a drink of water before shooting the video and got some water down the wrong pipe. I was shooting a video for my students and I was in a hurry.
ABOUT US:
Weber State University (WSU) - Automotive Technology Department - Transmission Lab. This video demonstrates the operation of a typical manual transmission. See the parts of a manual transmission in operation. The information here applies to most manual transmissions and transaxles. This particular transmission is a 1995 Toyota "Truck" 5-speed Aisin R150 model. A version of this same transmission is used in some newer vehicles today. We teach current vehicle technologies to our automotive students at Weber State University and online. For more information visit: www.weber.edu/automotive
This video helps demonstrate part of the following NATEF Tasks:
A3.C.3 "Diagnose noise concerns through the application of transmission/transaxle power flow principles.", a priority 2 task.
A3.C.4 "Diagnose hard shifting and jumping out of gear concerns; determine necessary action.", a priority 2 task.
This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see www.weber.edu/automotive/J_Kel...
