Electronic Cautions

performance Modes

he transmission control module (TCM) programming allows the driver to select among various modes for enhanced performance based upon driving conditions. he TCM itself has the capability to change modes automatically when speciic conditions are met. hese modes will alter shift feel, and could be confused with shift problems by the driver if they are unaware of the TCM programming.

•Economy Mode/Power Mode The transmission is programmed to start and operate in Economy Mode. This shift strategy sets the shift points to occur at a lower speed than Power Mode to maximize fuel economy. The TCM will automatically switch to Power Mode when the driver accelerates more aggressively (higher engine load), or at higher speed, maximizing performance.

•Winter Mode is activated by the driver by a switch on the shifter. This mode starts the vehicle in 3rd gear to reduce tire slip on icy/slippery roads. Once the vehicle is moving, the TCM will automatically shift to the appropriate gear. Shifting into manual 1st or 2nd will cancel Winter Mode.

•Neutral Control is automatically activated by the TCM if the vehicle is in Drive and comes to a stop for longer than 2 seconds with the brakes applied. This condition allows the C1 (forward clutch) to be disengaged, placing the vehicle in Neutral, for improved fuel economy. When the brake is released, the C1 clutch is automatically applied and the vehicle will take off in 1st gear.

•Hill Hold The TCM monitors vehicle speed to determine if the driver is coming to a stop on a hill. If so, the TCM will automatically apply the B1 (2/4 brake) to prevent vehicle rolling. Upon takeoff, the B1 brake is released, and the vehicle moves forward in 1st gear. The TCM will disable Neutral Control if Hill Hold is activated.

Solenoid

Solenoids

his 60-41SN unit uses ive solenoids (Figure 1).

•The S1 solenoid is an on/off style, operated by the TCM to control the 2-3 shift.

•The S2 solenoid is an on/off style, operated by the TCM to control the 1-2 and 3-4 shifts.

•The SN solenoid is an on/off style, operated by the TCM to operate Neutral Control.

•The SLU linear solenoid is pulse width modulated by the TCM to operate the converter clutch.

•The SLT linear solenoid is modulated by the TCM to regulate line pressure.
