GM Transmissions & Difficult Shifting

Posted on by

The eight-speed automatic transmission found in certain 2015-2019 Chevrolet, Cadillac and GMC vehicles have a defect that makes the vehicle hesitate and jerk when accelerating or slowing down. Owners say that the 8L90 and 8L45 transmissions experience hard shifting and eventual engine damage.

According to a class action lawsuit filed last year, “Drivers attempting to accelerate or decelerate feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or ‘hard shift’ when the vehicle’s automatic transmission changes gears.” The shuddering, shaking, jerking and hesitation is believed to be related to friction within the transmission and/or torque converter causing metal shavings to be circulated throughout the transmission.

The vehicles affected by this problem include:

  • 2015-2019 Chevrolet Silverado
  • 2017-2019 Chevrolet Colorado
  • 2015-2019 Chevrolet Corvette
  • 2016-2019 Chevrolet Camaro
  • 2015-2017 Cadillac Escalade and Escalade ESV
  • 2016-2019 Cadillac ATS and ATS-V
  • 2016-2019 Cadillac CTS and CTS-V
  • 2016-2019 Cadillac CT6
  • 2015-2019 GMC Sierra
  • 2015-2019 GMC Yukon and Yukon XL
  • 2015-2017 GMC Yukon Denali and Denali XL
  • 2017-2019 GMC Canyon

Air conditioning problems are another common complaint affecting certain newer Chevrolet, Cadillac and GMC vehicles. Owners say the system is not strong enough to withstand the internal and external pressures. Leaks eventually occur causing damage to compressors and condensers and expensive repairs.

The vehicles affected include:

  • 2015-2017 Cadillac Escalade
  • 2014-2016 Chevrolet Silverado 1500
  • 2015-2017 Chevrolet Suburban
  • 2015-2017 Chevrolet Tahoe
  • 2014-2016 GMC Sierra 1500
  • 2015-2017 GMC Yukon

General Motors has decided that a defect relating to vehicle safety exists in certain 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 crew cab trucks.
