For several months, my vehicle had been shaking while driving and when idle; felt as though the transmission was slipping. When reported to the dealership and after constantly having the vehicle serviced, no issue could be found. Recently the vehicle stalled while attempting to reverse. The vehicle had to be turned off and restarted before the gears could be switched properly. No indicator lights came on before or after the incident. The vehicle was taken to the dealership and diagnostics resulted in the following: ‘Torque converter shutter gears 4 & 5 slipping. Abnormal signals and solenoid. Metal debris found in fluid. Replacement of transmission suggested.’ The advisor stated that the vehicle is unsafe to drive until the transmission has been replaced.
