Transmission/Transaxle Controls
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2000 Nissan Xterra, 2000 Nissan Sentra, 2000 Nissan Quest, 2000 Nissan Pathfinder, and 2000 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
Some A/T models are equipped with an electronic Transmission Control Module (TCM). TCM receives input signals from ignition coil (RPM signal), idle switch (on-off signal), throttle position sensor (variable signal) and full throttle switch (on-off signal). Based on these values, TCM calculates optimum timing and duration to energize shift solenoids, overrun clutch solenoid and lock-up solenoid. TCM also indicates when Overdrive (OD) is engaged by illuminating OD indicator light.
