Typical transmission symptoms owners report

  • Right rear axle seal leaks lubricant onto the brake rotor, caliper, and pads, sometimes described as a common problem leading dealers to replace the whole axle assembly.
  • Automatic transmission produces irregular or rough downshifts in lower gears, felt and heard while braking, sometimes with a forward surge that feels like being hit from behind.
  • Gear shifter fails to engage reverse, with the reverse and drive lights flashing on the shifter column instead of a warning light.
  • Owners report the vehicle losing motive power and stalling at highway speed, requiring a battery terminal adjustment to restart.
  • One owner described steering drift and shuddering ('death wobble') at higher speeds occurring alongside a leaking rear axle seal.
