OSC - Transmission DRIVE MODES: Notes
WARNING: This page is about a different car, the 2004 Lincoln Navigator. 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 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:
- GEAR - Commands the PCM to upshift or downshift.
- TCC - Commands the PCM to lock or unlock the torque converter clutch.
- EPC - Commands a high pressure value during an upshift or downshift.
