Transfer Case Operation 

Weber State University (WSU) - Automotive Technology Department - Transmission Lab. The operation and power flow of this part-time 4WD transfer case are very similar to other transfer cases manufactured by New Process, New Venture Gear, Borg-Warner, Magna Powertrain, etc. This transfer case is the Toyota JF1A Transfer Case. The JF1A is built by Aisin, a Toyota-owned company. This transfer case is typically used in 2007 through 2013 Toyota Tundra trucks. The 2014 Tundra uses a Borg-Warner transfer case.
