General signs:
* Increased fuel consumption: A faulty lock-up solenoid can cause the torque converter to slip, which increases fuel consumption.
*Poor Gear Shifting: A faulty solenoid can cause difficulty shifting, especially into higher gears.
*Elevated Transmission Fluid Temperature: A faulty solenoid can cause the transmission fluid to overheat.
* Trouble Codes: A faulty solenoid can cause transmission related trouble codes.
Specific symptoms of a malfunctioning torque converter lock-up solenoid:
* Torque Converter Slip: A faulty solenoid may not engage the torque converter lockup, causing it to slip. This may feel like a slipping clutch or loss of power.
*Higher RPM on the Highway: If the solenoid is not locking the torque converter, the engine RPM on the highway will be higher than normal.
*Transmission Vibration: A faulty solenoid can cause transmission vibration, especially when driving at cruising speeds.
*Lock-Up Delay: The solenoid may not engage the torque converter lock-up immediately, resulting in a delay in shifting.
*No torque converter lockup: The solenoid may not engage the torque converter lockup at all.
