OSC - Drive Mode

The Drive Mode allows control of 2 transmission functions. Each OSC function has a unique set of vehicle operating requirements that the technician is required to meet before he/she is allowed to operate OSC. The recommended procedure, when using the Drive Mode, is to command one parameter at a time. The Drive Mode allows the technician to control the following OSC functions on the transmission:

• OSCGEAR - Directs the PCM to upshift or down shift.
• OSCTCC - Directs the PCM to engage or disengage the torque converter clutch.
