Typical transmission symptoms owners report

  • Automatic-transmission cars unexpectedly downshift into a low gear at highway speed, the RPM spikes past 4,000, and the vehicle loses power while the traction control light stays on.
  • Some vehicles will not upshift out of first gear after the sudden downshift, and the gear indicator on the dashboard goes blank.
  • Manual-transmission owners report the engine surging or lurching forward on its own when downshifting through a curve or turn, with RPM jumping between roughly 2,100 and 4,500.
  • Manual-transmission owners also describe grinding when shifting from first to second gear even with the clutch fully depressed.
  • Several drivers say the loss of power and forced low-gear condition happened repeatedly and could not be duplicated or diagnosed by a dealer technician.
