TECHNICAL INFORMATION
βββββββββββββββββββββββββββββββββββββββ
The transmission solenoid is an electronically controlled hydraulic valve located inside the automatic transmission valve body.
Depending on the transmission application, this 77942 solenoid is used to control specific hydraulic circuits related to torque converter clutch operation, pulse-width modulation, or 3-2 downshift control.
In selected 4L60E applications, the 77942 solenoid may function as the 3-2 downshift solenoid or TCC / PWM solenoid depending on year and transmission configuration.
In selected 4T65E applications, this solenoid is commonly used in the TCC / PWM circuit.
The TCC / PWM system helps regulate torque converter clutch apply pressure and engagement.
Correct solenoid operation is important for:
β’ Torque converter clutch apply
β’ Torque converter clutch release
β’ Controlled TCC engagement
β’ Hydraulic pressure regulation
β’ Proper transmission operation
β’ Smooth converter clutch engagement
β’ Correct downshift control in applicable 4L60E units

COMMON FAILURE SYMPTOMS
βββββββββββββββββββββββββββββββββββββββ
Possible symptoms related to a TCC / PWM or 3-2 downshift solenoid problem may include:
β’ Torque converter clutch not engaging
β’ Torque converter clutch staying engaged
β’ Converter clutch slipping
β’ Harsh TCC engagement
β’ Delayed lock-up
β’ Transmission shudder
β’ Incorrect 3-2 downshift operation
β’ Harsh downshift
β’ Check Engine light
β’ Transmission diagnostic trouble codes
β’ Increased engine RPM at highway speed
β οΈ IMPORTANT:
A diagnostic trouble code does not automatically mean the solenoid itself is defective.
Similar symptoms may also be caused by:
β’ Internal wiring problems
β’ Damaged connectors
β’ Valve body wear
β’ TCC regulator valve wear
β’ Low hydraulic pressure
β’ Contaminated transmission fluid
β’ Torque converter problems
β’ Internal transmission damage
β’ PCM / TCM command issues
Professional diagnosis is recommended before installation.
