Stealth R/T Turbo V6-2972cc 3.0L DOHC Turbo (1996)
Control Module: Description and Operation
The Transmission Control Module (TCM) calculates transmission speed and gear ratio based upon input signals from Pulse Generators A and B.
The TCM controls the torque converter damper clutch based on the input operating conditions.
To prevent driveability problems, the TCM turns the damper clutch OFF under the following conditions:
First and reverse gears- To secure quick acceleration at start
Below approximately 800 RPM- To secure easy start
Large throttle opening at engine speeds of 2,000 RPM or less- To secure quick acceleration
Engine braking- To prevent deceleration shock
3-2 downshift- To secure shift feeling
Engine coolant temperature below 122°F (50°C)
If all operating conditions are correct, the TCM switches a signal ON to the Damper Clutch Control Solenoid Valve to engage the torque converter
