OSC - Transmission DRIVE MODES
WARNING: This page is about a different car, the 2003 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The DRIVE MODE allows control of three transmission parameters. Each mode/parameter has a unique set of vehicle operating requirements that the technician is required to meet before being allowed to operate OSC. The recommended procedure, when using the DRIVE MODE, is to control one parameter at a time.
The DRIVE MODE allows the technician to carry out the following functions on the transmission:
- GR_CM - allows upshifts or downshifts.
- TCC - engages or disengages the torque converter clutch.
- EPC - increases/decreases EPC pressure.
