Torque converter clutch pulse solenoid
Ok DIYers, I need Help... 2000 buick century custom. Put car on quality scanner and receive a p1860b code. This is a torque converter clutch pulse width modulated solenoid. Symptoms: at speed, is like a miss or downshift feel. this was at first. now getting surges and jerks at start and at speed. It happens a lot but is not constant. Last night and this morning no problems at all. Do you think changing the solenoid will cure this problem.
