Trans-Drive Mode

DRIVE MODE allows control of 3 transmission modes. Each mode has a unique set of vehicle operating requirements that must be met before being allowed to operate in OUTPUT STATE CONTROL. When performing DRIVE MODE, control one mode at a time. DRIVE MODE allows the following modes to be entered and performed on transmission:

1. GEAR MODE  - Allows upshifts or downshifts.
2. TCC MODE  - Engages or disengages TCC.
3. FIRM_SFT MODE  - Commands a higher control pressure during upshift.

PC solenoids are not directly controlled during DRIVE MODE testing. Pressures may be raised during an upshift in FIRM_SFT GEAR mode to test transmission shift operation. In DRIVE MODE, transmission can be commanded into any forward gear. Engine must be running and transmission gearshift lever in "D" or "D5" position. Vehicle speed must be more than 2 MPH and TCC solenoid must be OFF.
